"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."
This refractometer is for measuring the sugar content of beer and includes an automatic temperature compensation of 10 - 30 degree Celsius. Ade Advanced Optics-Dual range refractometer measures the Brix and Specific Gravity of your Wort or wine..

After performing the calibration, it confirmed the Specific Gravity scale on the Refractometer was exact for Unfermented Wort. Then calibrate with unfermented wort you know the Specific Gravity (use a Hydrometer)."
"Monitoring the runnings of the mash and the progress of the boil were annoying before because I always had to get a pitcher and chill a sample down."
"I have compared it to my hydrometer reading and it is dead accurate."
"I'm thinking this may be due to temperature differences impacting the reading but I have yet to confirm. Also if you are measuring fermented beverages, remember not to use a refractometer in the presence of alcohol as it changes the reading."
"Upon opening the box, you get the refractometer, a user manual, one pipette, and a microfiber cloth to clean the glass plate. Then I decided to go ahead and get it calibrated for wort, so I mixed DME into 1200ml of water to equal out at exactly 1.040 SG."
"Made a functional check sugar solution, (not really a calibration standard, but good enough to instill confidence)."
"This thing is amazing."
"Very easy to read compared to a hygrometer, and the 3 drops are easy to cool down compared to the 6 ounces in my test jar."
Product feature This optical refractometer (honey meter) has 3 scales: 10 - 33 % for measurement of honey moisture, 58-90% for brix, 38 - 43 Be for Glucose Baume.

"Refractometer is well protected in a heavy plastic case that contains the instrument, screwdriver, pipettes, cleaning cloth and instructions."
"I tested two of my honey varieties (early summer and late summer), and readings were as expected."
"The user manual was obviously not written by an English writer."
"Works Great."
"worked well for our purposes, simple to use and not terribly expensive.."
"Easy to use."
"purchased this as a gift for an aspiring beekeeper--very nice--fast shipping."

I am not a Professional HVAC or auto mechanic but I do a lot of work myself on my home and vehicles.. An IR thermometer has many uses. I bought this as a homeowner to verify hot/cold spots around my home. I decided I would go with Etekcity Line IR thermometer based on Amazon Best seller Etekcity 774 (best seller most reviewed and priced very affordable at $16.88). After researching other Etekcity models I found many different options that offered different ranges, features, and spot/distance ratios up to 16:1 with 12:1 being the higher standard and what most higher end brands have.. spot/distance ratios range from 8:1 to 16:1 in this class of IR tool. I submitted a question to them through Amazon and Etekcity responded within the same day offering to call me , as I had a lot of questions..I was able to immediately open a chat conversation with Etekcity customer reps and they were VERY helpful in explaining to me the advantages / differences in all of their IR thermometers. Etekcity 1022D- $19.99 Etekcity Lasergrip 1022D Non-contact Digital Infrared Thermometer, Dual Laser, Blue. my first IR from Etekcity: I like the idea of Dual lasers & adjustable emissivity. Etekcity 800 Lasergrip - $25.98 Etekcity Lasergrip 800 Non-contact Digital Laser IR Infrared Thermometer Temperature Gun, Yellow/Black. Features: Single Laser. 16:1 distance to Spot ratio. Emissivity- FIXED at .95. Range: -58℉ - 1382℉. After a disappointing test of the Etekcity 1022D I read reviews and decided to look at the 800, It features better accuracy at range with a 16:1 distance spot ration. *** Etekcity 630 Dual Lasergrip - $29.99 Etekcity Lasergrip 630 Dual Laser Non-contact Digital Infrared Thermometer, Gray and Black. First impression was how it was packaged in a nice solid cardboard box ( unlike the plastic blister packs of the others including the Klein. The most features, options and in my tests most accurate ( accuracy is negligible between 800 & 630 both are well with in the +/- .5 to 2.0 tolerance). Features: Dual laser for better accuracy. 16:1 Distance to Spot Ratio. Emissivity: ADJUSTABLE. Range: -58℉~1076℉. Multi function menu options ( MAX/Min temp setting, AVG and Diff/ TD). I chose the 630 over the 800 mainly due to the extra menu options ( AVG, MAX, MIn , Diff) adjustable emissivity ,and dual laser aside form that the 800 & 630 perform identically. the 1022D and 774 are priced well at under $20.00 but for more features and higher specs I think one will not go wrong with the Etekcity 800 or Feature rich Etekcity 630."
"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."
"I bought this product because I thought my refrigerator was not cold enough, and I saw the tech that previously came out using a lazer thermometer to gauge the temps inside."
