## Description

3-in-1 Antifreeze Tester in Fahrenheit Scale for Checking Freezing Point and Concentration of Ethylene Glycol or Propylene Glycol Based Automobile Antifreeze Coolant, Also for Battery Acid Condition: desertcart.com: Industrial & Scientific

Review: Accurate and easy to use - It works great. I really need it because my chiller and equipment are placed outdoor. The temperature sometimes drops below 20 F in winter.
Review: Well Made and Very Useful - Using in my motorhome, not just for antifreeze, but especially the six 12-volt wet cell batteries. Tells me which cell might be failing. Seems accurate, well made, easy to use. Buy it.

## Features

- Function 1: Measuring freezing point temperture of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale range: ethylene glycol base: -84°F-32°F, propylene glycol based -60°F-32°F
- Function 2: Measuring concentration of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale Range: ethylene glycol base: 0-70% propylene glycol based 0-63%
- Function 3:Measuring specific gravity of battery acid and provide a quick reference of battery charge condition. Scale Range:1.100~1.400kg/l
- Features automatic temperature compensation: makes it more convenient to use in different temperature.
- Quick and easy: Just need 2-3 drops of solution and a few seconds, you can get accurate readings. And no battery needed.

### ⭐⭐⭐⭐⭐ Accurate and easy to use

### ⭐⭐⭐⭐⭐ Simple To Use and Accurate
*by Z***Z on August 19, 2025*

This is my first use of a refractometer style antifreeze checker and it was impressive. The instructions are clear and use is easy. I confirmed the factory calibration with distilled water which showed 32 deg freeze point / 0% antifreeze. A known 50 / 50 glycol mixture showed right at 50%. This gave me confidence that readings of unknows should be accurate at well. This wins hands down over the floating balls or arrow style antifreeze checkers. Very happy with the quality and performance for the price. The storage case and the included droppers were better than expected quality.
