Featuring automatic temperature compensation and requiring only 2-3 drops of fluid, it delivers reliable results without batteries, making it an essential portable device for diesel engine maintenance professionals. ## Description Product description aichose is a professional brand of supplying various kinds of liquids measuring instruments. The refractometer series are based on the principle that the refractive indices of liquids change when the concentration change. It's portable, easy, quick and no battery required, easier and more accurate than a traditional hydrymeters, more affordable than a digital meter. It's a perfect tool for adult or young, home or professional use. It features high-quality optics with smooth focusing. Its main body is made of aluminum alloy. The internal optical lens with high refractive index make up the precision optical system.The instrument is resistant to abrasion and corrosion, can be used to measure the general corrosive liquid. (But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. ) Diesel Exhaust Fluid Concentration Refractometer EPA regulations require all diesel engines manufactured on or after January 1, 2010 to meet lowered NOX emissions standards. Most heavy duty engine (Class 7-8 trucks) manufacturers, have chosen to equip SCR, like Detroit Diesel (DD13, DD15, and DD16 models), Cummins (ISX line), PACCAR, and Volvo/Mack. SCR-equipped engines require the weekly addition of Diesel Exhaust Fluid (DEF, a kind of urea solution) to enable the process, and to ensure the SCR system work properly, operators must ensure the DEF concentration in their vehicle being at about 32.5 percentage. This refractometer is designed for measuring the Diesel Exhaust Fluid (DEF) concentration, makes it very quick and easy to test the quality of DEF, just need a few drops of the fluid and a few seconds, you can get the result. Measuring Scale Range:0%-40% Urea Concentration. - Product Features ATC FUNCTION The build-in Automatic Temperature Compensation feature makes it get consistently accurate reading, no need to control the liquids temperature deliberately, just make sure it's at roomtemperature ( during 0-25 ℃). EASY TO USE Just take a few drops of your liquids on the prism and hold the refractometer to the light, then look through the eyepiece, you can get the reading. No need lookup table and no waste! PORTABLE PACKAGE The refractometer comes with dropper, screwdriver, user manual and cleaning cloth, all included in a hard compact case, the item dimensions is 8"x3"x2", the item weight is only 8.8 ounces. makes it very portable and easy to carry.

When you put your sample to be tested on the daylight plate, make sure the liquid spreads across the entire surface of the prism without air bubbles or dry spots. Clean the instrument with a soft cloth after each use, keep the refractometer dry and clean, which will keep the instrument accurate and durable. Do not put the entire instrument into water to wash, this may lead it to be foggy or rusty inside. Please do not loose any connection part, and don’t dropping, colliding, shaking the instrument intensely.

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. ## Frequently Bought Together - DEF Refractometer for Measuring Diesel Exhaust Fluid Concentration of Diesel Engines - Performance Tool W16500 Professional DEF Tester (Disc Type DEF, Diesel Exhaust Fluid tester) - B3C Fuel Solutions DEF 7-040-9 Diesel-Exhaust-Fluid Contamination Test Strips (Pack of 100) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/77422768-def-refractometer](https://www.desertcart.com.ar/products/77422768-def-refractometer) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-06-03*
