"I have this test pen for 3 months, just press the button to test your water quality, it can turn off automatically in about 5 minutes."
"The well is 780 feet deep and is pumping water, or sucking water through wet sand, this is not good, and makes the water hard."
"This is a good TDS meter!"
"Very good price, seems to be working well."
"!Just dip it into the water and if you can't see the digits there, press the hold button and pull it out."

"Very handy to have because I have various plants that require different levels of moisture and they cannot all be watered at the same time."
"Works fine and safe me dirty fingers , had one before but that walked away from me ( "with a friend ")!"
"I grow a lot of African Violets as well as other plants and this gadget is so handy, especially for those other plants that I have in pots on the deck outside."
"Bought 2 since we have been using them a lot for quite a long time and this is my favorite brand but one broke within 7 months."
"Not that accurate, not recommended to,leave it in the soil..must be removed after readings are taken and wiped clean..Would not buy again. I must add..The seller is fantastic and had made all things right, without my even asking!!"
"I am very happy with this purchase - I have tons of houseplants and the worst thing you can do is over water them and with this I don't."
"Sounds like several people had trouble with these not working, so until another moisture meter made of better quality comes along, guess we'll pass on this item."
Best Lab Spectrometers

Reviews
Find Best Price at Amazon"On the blue side of the spectrum mine was off 5nm, and in the middle of the spectrum (green) mine was off 3nm in the other direction. I calibrated mine in both the blue and green wavelengths, but don't have good way to calibrate the red end of the spectrum due to lack of a know wavelength source in that range. It takes time and effort to collect meaningful performance data and write a quality review -- If you found this review helpful please vote 'Yes!"
"This unit works extremely well."
"Also if the light source is not very bright then you might not be able to see the scale since it uses ambient light to make it visible."
"However, it is still useful for what I wanted -- checking the smoothness of the light from LED lamps and CFLs."
"Good for rating light color temps."
"This spectroscope is fun and easy to use."
"Works well, wish gradients were further defined."
"This item is also a useful photography accessory - if you plan on using a light, a quick check of the spectra can give you an idea of how good the colors will be."
Best Lab Multiparameter Meters
A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. The lower the TDS level, the purer the water, with 0 ppm being pure H2O. This TDS tester is ideal for all water purification applications, wastewater regulation, aquaculture, hydroponics, and colloidal silver.

"We received from a third party supplier Solutions that were calibrated for TDS to Micro siemens (μS)not ppm. When I bought the 342 ppm solution to confirm, I was reading 155 ppm. When I tried to adjust the meter with the adjustment screw, the highest I could get up to was 221 ppm."
"However, note that the picture Amazon provides is apparently the TDS-4TM, which is NOT what you'll receive if you select the "Ships and Sold by Amazon.com" option."
"We use it to check our tap water as well as drinking water we buy."
"We have a reverse osmosis water filter at home and this meter help us to monitore when to change filter cardiges, etc."
"Tried using this a few times but It gave inconsistent readings that didn't give me much confidence in."
"it tests minerals in my Zero pitcher and lets me know when to change filter."
"Says for more information about calibration and maintenance to go to a link that does not work."

"The refractometer comes with a nice zippered pouch, instruction booklet, small screwdriver for zeroing the unit as well as a small plastic siphon. I tested a store bought apple and discovered it was slightly above average."
"I would say works well for SAP not syrup, you need a refractometer with a higher brix scale for maple syrup, dont want anyone else to make the same mistake i did, but still good to know what your sugar content of the sap is and when the season is over for the noobs. it actually works for syrup if you dilute it in a 2-1 ratio water to syrup, you would be looking for 22-23%. 2 teaspoons of water to 1 teaspoon of maple syrup."
"It works quite well for the price and is the exact same model as the one my professor allows the students to borrow during lab."
"Normally I'd expect to pay over $100 for one of these - so finding a temperature-compensated refractometer for only $35 sounded like a gamble, but one worth taking."
"Yes, a hard case."
"I've been using it on tomatoes and I think it seems to be accurate."
"While I imagine it will do just fine, I chose this model instead of the 0-10% model because this model appeared to come with a plastic case."

"I've been testing my pool water with both of my kits just to verify the results of the ColorQ Pro."
"I tested my pool water with this as well as had the pool installer take a sample and test it. I am not saying I will not use strips for a quick test, but this is great for a once a week or every two week test for added accuracy."
"Compared to two different types of tests (liquid and strip test) in three different pools."
"Calibrate it, fill each container with a water sample, apply chemical per directions, insert into machine, press button and read the results. I changed the batteries and found some corrosion on some of the circuit board."
"This prevents wild swings in pool water quality as with test strips if you let something get too far out of the desired range, then have to apply massive amounts of someothing to get the water back to where you want it."
"I wish it had a method of measuring salt level though."
"I had a tough time discerning the colors with other kits."

The relative function, expanded display resolution, and temperature probe are all helpful in pinning down intermittents. Tested well within published specs when compared to 2 other DMM's, a function generator, tray of precision resistors, and several different capacitors. Handy for finding leaky PS filters, funky varactors, and borderline chip caps. You can't go wrong with any of their meters, but if you're planning to expand your hobby or upgrade your bench, give this model a look."
