Reviews
Find Best Price at Amazon"No real issues there, although I had to relocate it to get a better stream of air (the initial mounting location would not trigger the change, probably due to a lack of adequate pressure). So I deducted two stars since most people will need those detailed instructions, as they are not electricians or HVAC contractors."
"You cut the white wire and attach each end of the white wire to one of the posts on the switch."
"If you have any concern about low pressure differential to trip the switch in the duct work where you are installing this, pick a better location with a higher pressure differential- the switch is not reliably as sensitive as I had hoped it was."
"I want to add a booster fan for the kitchen exhaust as the fan from the microwave is not powerful and a pretty long distance to the outside wall with the 4" pipe."
"#2 black wire common from house direct to fan. #3 connect line to "open" on switch back to white wire on fan to make the loop. #4 connect earth to switch box and duct fan. Turns fan on immediately after furnace kicks on."
"Placement is important, I tried using it where the booster fan is ( has to be upstream from the Booster fan ) but the pressure change in the duct was too low so it didn't work."
"I placed the switch downwind of the 1st floor damper near where the branch duct with the booster fan takes off."
"I moved it 18' from the Tjernlund DBF2 Dryer Duct Booster Fan and was too sensitive."

I'd say it works reliably probably about 97% to 98% of the time, and the good thing about this, over the PIR sensors I've tried is it NEVER gives false alarms, so it is a great improvement over any PIR sensors I've tried... but I'm rating it only 3 stars because I'd expect this to work better since it's a broken beam system..."
"I have had the BBT-2500 sensors for a year now and this is what I have experienced: first, they are hard to "pair" until you realize that just because the power buttons light-up that doesn't mean the devices are turned on. I have an automatic gate nearby that has 12 volt power so I just ran wires to the transmitter and receiver to keep them charged through the dark winter months."
"Works well so far and I have had this for over 1 month."
"I have these installed across my driveway covering about 25 feet of frontage and along side a fairly busy road, maybe 4 feet off the shoulder."
"I have had to replace these 3 times now, The problem is not in the product but in the location of installation."
"Installed across our driveway and spaced about 40ft apart, and at a distance of about 100 yd to the receiver located just inside a window at the front of our house."
"Tried leaving them in the sun to charge assuming the batteries are dead, that did not help. There is nothing anywhere on the internet, or their web site accept very the very unhelpful, incomplete users guide."

"I was using it to fix an electrical box in a basement the other day, and the clip was invaluable for keeping the light where it needed to be."
"it is also very sensitive, i'm still getting used to it after a month, it's about as reliable as any other hot stick, but it looks pro, and the LED flashlight is nice and bright."
"Odds are it will get more use as a flashlight now that I have all the ceiling fans and lights installed, but it's still worth having around."
"Pros, It works great as a flashlight on the side of my hardhat with the bracket. It also clips nicely to the side of panels allowing free hands. This makes it a Con also because when your in a box with multiple circuits you cant tell which wires are hot and which aren't. With their outstanding reputation Fluke just doesn't cut it in this department."
"It has one function you press the on button and the LED flashlight is on and your suppose to be able to see the red indicator when voltage is present."

"This device is probably the best single purchase that I have made on Amazon in my three-plus years of Prime membership. It functions wonderfully as a distance thermometer, shining a tiny red dot on what I'm measuring and, based on comparison with a thermoscan camera at work, is pretty accurate across a range of temperatures from 0°F up to about 400°F. The button that turns on the device has a very soft click, barely perceptible, so it won't distract your faithful (or in the case of cats) persistent companions. *Probably won't reliably measure the temperature of flames at a safe enough distance, so don't get too close to fire."

So you'll need to find a very small #3 Phillips head screwdriver just to remove the batteries, and let's hope you don't have to do this at night or in the bush.

Basically, you can work on most panel boards / switch gear and anything down stream of them (i.e. - feeders, outlets, hard wired equipment, and anything plugged into them.). CATIV is the only rating higher and it adds service drops to the list as well as underground installations. So basically CATIII is the MINIMUM rating you want on your meter and you can't probe the main drop from the power company. I love the sturdiness of this meter, it a Fluke, so it's the brick crap house of DMMs. The rubber holster offers excellent 5 side protection and it feels good in the hand. Most people fail to realize just how much force 10A can carry; this meter uses a single high quality ceramic HRC fuse and all of the standard additional suppression devices to give the user maximum protection. The case is designed with a deep lip / blast shield as well to protect against debris being blown out the sides in the event of truly catastrophic failure. This is a low impedance voltage test that operates on something close to a 3,ooo Ohm resistance. Flipping to the low impedance mode allows this ghost voltage to “dissipate” and read what's really on the line (which should be less than half a volt on a circuit that’s de-energized.). The resistance on a PCB in electronics circuit can often be much higher than 3,000 Ohms...you could short out that segment of your board by allowing current to flow through the meter as apposed in parallel to it. This is why traditional meters use mega ohm class resistors to test voltage, and most of the time that's fine. So always start out in "normal" volts AC or DC then if ghost voltages are suspect, then switch to the LoZ range. It's a latched system which means you get a positive tone every time a circuit is completed. The "Volt Alert" is a non-contact voltage detector that functions the same as those pen style testers that have been on the market for years. It's nice to test walls for live electrical lines prior to drilling or nailing into them. It features high and low sensitivity modes for different wall thicknesses. However in my opinion the amperage range is quite useful for a general purpose meter and perfectly geared for electricians or homeowners. It's written in 9 languages but it's still simple and easy to understand while at the same time giving the user all the information and data that they could possibly need about this meter. So it drops a digit every factor of 10 up to 600.0 (i.e - 6.000, 60.00, 600.0) Now having said all of that, the accuracy isn't reflected in the screen's numeric resolution. Basically, you look at the reading on the display (we'll imagine measuring against a precision voltage reference of 1.000V) The first step is to add AND subtract half of a percent to get a range (in our example 0.995V & 1.005V) then you add and subtract 2 counts. Honestly for precision testing that could be quite a bit, which is why high accuracy bench top meters costs hundreds or even thousands of dollars, however for general purpose measurments, this is actually is really good accuracy. This would leave my other hand free to hold the meter and push the button. Just mark the price up another 2 bucks and give us a pouch for our meters here Fluke! A set of alligator clips would've been nice, but alas nope... Sold separately. Honestly, I have a few Fluke products and a disappointing lack of accessories is actually a common problem. If you find a Fluke Kit for the meter you're interested in at a reasonable price...GET IT! Sure Fluke has a "market" and therefore a "price" in mind, but they build their units to a "standard" first. At the end of the day, they know that these units have been tested rigorously and "proven" so that when they need quality and survivability, as well as maximum personal protection these meters will perform."
"Best meter I have!"
"It does what it is meant to do."
"Awesome Voltage meter at a really good price."
"I especially like the Lo-Z setting, which pays no attention to the ghost voltage one otherwise sees in mains power (120V 60Hz) because of voltage induced from other lines in the vicinity of those in the circuit your measuring."
"You can't go wrong with Fluke."
"The NCV checker is a great little extra just to quickly check if a panel is really dead."
"I use it to trouble shoot access control and alarm security systems."

Most of us are carrying around super high quality video monitors in our pockets, so I decided to give this device a try. Also those more expensive units have the cable connected to the screen which is usually mounted to some kind of handle. I have a magnet attached to the back of my phone and it just stuck right up to the pan on the bottom of the transmission. As to durability, I have only had it a week or so and it's holding up so far, although I can envision some problems over time with repeated flexing of the cable. The view you get with it is just like with your phone camera, meaning if you rotate the scope clockwise, the image will also turn which can be disorienting. I got the camera in the right orientation and then bent a "W" shape in the cable a few feet back from the end of the scope. The app allows you to show a mirror image of what you are scoping and you can get rid of the icons on the screen so they don't interfere with what you are trying to look at with the camera. Pros: Price, image quality for live video, stills and captured video, long cable length, WiFi connectivity. Cons: Cheap WiFi box, barebones app, resolution not really changeable."
"I bought this inspection camera for my Dillon XL650 bullet press to be able to inspect brass bullet cartridges while reloading them."
"Really impressed with the Depstech Wifi Endiscope."
"For the price it is fine, but if you're looking to use it for serious inspection inside of things, be sure you have a light to chine into the item or run in separately."
"I purchased this endoscope because I didn't want to take all my kids to the dr when they are already not feeling well, making them more vulnerable to other illnesses, just for their doctor to say "it's a virus, just let it run its course" I wanted to be able to look in their ears and see if they might have an ear infection on top of a virus."
"Focus range is extremely limited: 1.2" to 2.4" (3 cm - 4 cm-- same as what the company website says). I'm quite surprised that something with such a tiny sensor would have such a minimum depth of field (focus) (Technically these are different terms, but bottomline is: is it sharp enough to tell what it is? The blurry results from my ear nixed any ideas of DIY colonoscopies.... the other areas it was pretty useless. In the past I've needed a device like this to examine a sewer line, look under tight spaces. I would suggest buying a lower resolution, USB connected endoscope, with a greater depth of field (focus range)."

"Update: As mentioned above, we purchased this because we were experiencing issues with our duct work and wanted to record the differences in wall/ceiling temps in the area where we believed there was a leak. We realized though that they reused some old ducts in our hallway and at the end of the hall was where the energy audit, and this temperature gun, were recording temps several degrees higher than the walls and ceilings just a couple of feet away. When we tore out the sheetrock, we found that at some point one of the duct branches had been changed and, instead of sealing it off, the end was left open and was blowing heated air into the chase, the attic, and my closet!"
"DUAL lasers in a pattern that crosses with one another. The meat in the middle of my freezer was -5 degrees and the icecream on the top shelf was 17 degrees.. That explains the frost/freezer burn my icecream was suffering from!"
"These readings are at the bottom and you can read those from your previous use but the temp at top in your bold numbers will now read the rooms temp as it apparently samples you room temp once it turns itself off? When it goes to sleep mode hit trigger once and release and it will wake up after about a second and you can read the previous readings you took using the small digits at the bottom, and you can scroll through the high, low, and average reading you had taken before with the mode button."
