🚀 Elevate Your Diesel Game!
The DEF Refractometer is a portable, precision optical instrument designed for measuring the concentration of diesel exhaust fluid in diesel engines. It features automatic temperature compensation, requires only 2-3 drops of solution for accurate readings, and is both durable and easy to carry, making it an essential tool for efficient diesel management.

Works perfectly
Works really well. Says to use distilled water to calibrate it. Adjustable eyepiece means you don’t need your glasses to read. Very easy to read DEF percentage level.

Must have for diesel owners!
I check the DEF quality of all the DEF I put into my diesel truck to make sure I don't end up with costly repairs. Takes but a minute to check the DEF quality of your DEF source. Highly recommended for any modern diesel owner.

Works a lot better than than the floating disks type. The disk type showed def being bad.

Been using these all my career
I've been using these on batteries all my career so I know if calibrated properly they are accurate. this one read right on 32.5 just like it is supposed to. The floating disk thing I bought didn't read at all. So for a couple of bucks more you can have something accurate. I'll be checking the calibration as soon as I can get some distilled water.

MUST HAVE TOOL if you own a modern Diesel
I used this tool to test and identify counterfit / defective DEF that I bought from Wallmart. Yes, bad DEF is actually a thing. I wish I had known that before the $845 dealer repair bill, and that I had bought this tool and tested the DEF. My loss - your gain.
