Very easy to use highly recommend
I bought it to check my DEF fluid and it worked great. I first tested with distilled water and it read 0, so no adjustments were needed. Tested the DEF and it was what is was supposed to be (32.5). Would recommend it you need to test anything.

THIS CAN SAVE YOU $$$$
Diesel engine owners know that this is a must have. This device can save you $$$$ in repairs. Bad DEF will ruin someone's day and pocket. This little device is awesome! This device will tell you if the DEF is good or bad with just one drop of DEF. Can't get easier than that. I've been using this device for 7 years.
