Worked exactly as expected. Helped me ensure I had perfect antifreeze / water mixture.

The refractometer works well, It was zeroed properly when it arrived and seems to be accurate. (I say seems because I have no means to be certain beyond trying straight glycol and water). My only complaint is that I wish the refractometer had a built in light source as it can be tricky to use with a flashlight.

At first I was looking for a refractometer just to test the quality of DEF fluid before I put it into my truck and to troubleshoot any poor quality DEF messages. I didn't know they made 4 in 1 testers until I started searching on Amazon. After reading the reviews on several refractometers I decide to purchase this 4-in-1 tester. I like the fact that it reads in fahrenheit and not celsius. It automatically compensates for temperature between 50 and 86 deg F. and tests 4 different types of fluid. Ethylene glycol based antifreeze ( DEX Cool ) , Propylene based antifreeze, Battery fluid and Def Fluid. It also has an adjustable eye piece to adjust the focus when looking thru the unit. It comes with a pull string storage pouch, 4 plastic eye dropper tubes to sample fluids, a lens cleaning cloth, instruction pamphlet and a tiny screw driver to adjust the calibration. It is a compact unit, approx 6" long. Calibration is checked by using distilled water. I checked the calibration of my unit out of the box and the calibration was dead on. For the price this is a great tester. I recommend it.

Perfect for what I need, at a fraction of the price of the tool trucks. Seems to be well made, time will tell.

Fells very sturdy. Worked perfectly out of the box. No need to calibrate.

I keep buying these for our HVAC technicians to determine how much glycol is circulating in boiler systems for radiant heat and snow melt systems.They work really well, even for people with glasses. And since they are reasonably priced, I do not get too upset if a technician loses one or forgets it on the job site.

I have used it to test by ethylene Glycol and propylene glycol antifreeze and it gives very easy results. I also used it to test the water in the bilge of my boat to see if it was salt water from the ocean or fresh water from rain.

Je fais du Kombucha et je voulais savoir si il y avait beaucoup de sucre. Après avoir testé avec des boissons zéro sucres et boissons très sucrées, j'ai pu vérifier que ça fonctionne très bien. Et ça vient avec un petit tournevis pour régler la lecture et une pipette pour extraire et déposer le liquide sur la plaque de lecture. Excellent produit.

The scale of this refractometer shows brix% and not antifreeze concentration like what is advertised. One star for false advertising.

Did not include Glycol readings on the visible scale. Useless.
