This antifreeze tester is exactly what I needed to check the freezing point of my coolant before winter hits. It’s super simple to use, and the Fahrenheit scale is perfect for my needs. It gives an accurate, reliable reading every time. I love how compact it is, so it’s easy to store in my toolbox. A must-have for anyone who wants to make sure their vehicle is ready for cold weather.

Impressed, needed something to test antifreeze and wanted something better than the old style floating ball tester. Very easy to use. Appears to be very good quality and nice case.

Accurate scales for both ethylene and propylene glycol, easy to adjust focus, and quality build. Recommended!Other reviews say it is hard to read... if the coolant is dirty, polluted or pH is extreme then the line will be fuzzy or more of a gradient. This is normal for all refractometers, if you doubt your readings then try it with new coolant and you'll see a well defined line.Concentration (freeze temp) is only one important coolant parameter, the other is pH. Coolant pH is generally considered ok when between 8.5pH and 10pH, slightly alkaline - it prevents corrosion. When the pH is out of range either way it's time to flush and replace. Especially if it starts becoming acidic (lower than 7pH) because it can cause damage to engine components and hoses. Test strips are really cheap insurance when used alongside the refractometer.This refractometer is a good product and a good value.

This is perfect for me. I test coolant on all kinds of engines daily. Case is nice and sturdy. Easy to calibrate and will keep its calibration as long as you’re not dropping it or throwing it in your tool box. I recommend this purchase.
