It works flawlessly!

Amazing! Just what I needed to ensure freeze protection in the winter for my difficult-to-drain Ford.

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.

J**.

Accurate, works as advertised.

Use this to test glycol on hot or chilled water systems. Costs 1/10th of the price of the name brand, works just as well.

Highly recommended

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.

Good Refractometer

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.

finally a fahrenheit readout

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.

Beats Prestones piece of crap

I’ve tested multiple cars and several gallons of concentrate that I had premixed 8 years ago. Easy to use and the instructions were easy to follow. Highly recommended.

Arrived broken

The tester works fine, but the blue case was broken, because Amazon doesn't care about packaging things properly. This is the second broken item I have received lately, both due to inadequate packaging.
