## Description

Antifreeze Refractometer 4-in-1 Coolant Refractometer Antifreeze Tester for Automobile Antifreeze System Diesel Exhaust Fluid, Battery Acid and Windshield Washer Fluid: desertcart.com: Industrial & Scientific

Review: Nice having a definitive answer to the freeze point of coolant - I had the old Prestone squeeze bulb device that seems to have served me well for the last 30 or 35 years. However, on my last coolant exchange on on3 of my vehicles, it was telling me the freeze protection was only down to 20 below....even though I had mixed the concentrated antifreeze with 50% distilled water...which should protect down to about 34 below. I checked, double checked, and checked a couple of my other vehicles and it again said about 20 below. I started looking for other options, and this product popped up. Reviews looked good, and there are several others available through other companies,....but most read in Celsius, and this one reads in Fahrenheit....which is what I'm familiar with. It works great and showed me I was protected down to 34 below....which seems right given my 50/50 mix. Easy enough to use, but you do have to wipe it down when done. Comes with a nice padded case to store it in. I'm very happy!
Review: Quality - Works great! Priced right

## Features

- 4 IN 1 FUNCTION: ❄Antifreeze refractometers measure freezing point of automobile antifreeze basied on ethylene glycol or propylene glycol, and measuring rang:-50 to 0 ℃. ❄Measure Urea Concentration in automobile diesel exhauset fluid (DEF) 30% to 35%. ❄Measure specific gravity of battery acid 1.10 to 1.40Kg/L. ❄Windshield washer fluid based on ethanol or isopropyl alcohol -40 to 0 ℃
- Better Accuracy& Reliable: ATC antifreeze coolant testers can compensate temperature automatically when ambient temp changes, excellent eliminate the deviation, and ensure the measured readings more precise
- Quick & Easy Using: Just 2 or 3 drops of solution, wait for few seconds and towards light, then get the accurate reading. The affordable coolant refractometer needs less sample solution than tradistional hydrometer and less expensive then digital refractometer but bettery accuracy
- Durable & Portable - Antifreeze tester is made of non-staining aluminum and ABS rubber, anti-rust, sturdy and resistand to abrasion for long perfermance. Comes with durable plastic box, lightweight, and easy for storage and carry with
- Practical Tool: The optics antifreeze refractometer is great tool to help you check freezing point of automobile antifreeze system, quick reference of battery charge condition, monitor DEF and windshield water fluid status

### ⭐⭐⭐⭐⭐ Great little gadget!
*by J***F on February 4, 2026*

This is my first refractometer, so was a little aprehensive about using one at first. There was no need. SUPER easy to use, and this particular one seems great. Comes in a little plastic case with foam lining to keep it safe and secure. Includes a tiny screwdriver for adjusting the calibration. It can be focused to perfect clarity, even if you wear glasses (I myself wear progressive bifocals). One note on that "clarity" piece. If you look through it without any liquid on the glass, you'll probably need to point it at a very bright light to see the measuring scales. Do not fret. As soon as you put a few drops of applicable liquid on the glass and close the little plastic cover over it, the view will be bright and clear in ambient lighting. After getting everything into focus, the first thing to do is calibrate the unit. Place a few drops of distilled water on the glass and close the plastic cover. The water should completely cover the glass, with no gaps. Wipe off any overflow from around the edges. Look through the lens to see the line where the white meets the blue. That should be at 32 F (the freezing point of water). If it is not (mine was about 1 degree off), then you need to calibrate it. Pull the rubber cap off of the adjustment port on the top side of the device. Grab the little screwdriver, slot it into the screw head, and while looking through the lens at the scale, slowly turn the screwdriver one way or the other, until the line is exactly on 32 degrees. It is now calibrated and ready to use. Great little tool that is super easy to use!
