Urea and DEF Tester - Refractometer Digital Tester That Measures Accurately and Quickly - The Best Choice for Your Diesel Vehicle - Limited Time Offer

very easy to use works excellent

Sent me returned opened item.

It does work, but even following the instructions it needs to be calibrated constantly. Slightly annoying when it takes 5 minutes just to check one sample of fluid. Otherwise, works great.

I have now ordered two of these units and both arrived with batteries already installed, hmmm! The display has no plastic removable adhesive that protects it as new product or unused, to be removed later. The cut out foam slot in both product boxes was empty and would normally contain 2 brand new AAA wrapped batters TO BE Installed, NOT already installed. I will test the unit against OTC Refractor product, but I don't trust the products that I have received so far. I'm suspicious because of the installed batteries, and Empty foam battery cut out slots. A nice looking product, will have to see how it reads and compares to OTC.

I purchased the vehicle urea test meter from Amazon after doing many comparing. I have to say that I was not disappointed. The test meter is very easy to use and provides accurate results in a matter of minutes. It also has a clear display that makes it easy to read and interpret the results.

In one principle, there is no consistent teaching about the transformation of power in order to prove one's ability. , in all refraction measurements. perfectly worked

pesimo, mediciones incorrectas

I am a truck driver and I use urea solution to reduce the emissions from my diesel engine. Urea solution is expensive and sometimes hard to find, so I decided to buy this urea tester from Amazon. It was easy to set up and use, and it gave me accurate readings of the urea concentration in my solution. With this tester, I can make my own urea solution by mixing water and urea granules, which are much cheaper and easier to get. This way, I can save a lot of money and time, and also help the environment by using less plastic bottles. I am very happy with this product and I recommend it to anyone who needs to use urea solution for their vehicles. It is well worth the price and it works great.
