Nice unit and makes me feel confident all is fine

I don’t know much about how refractors works but I changed coolant on 2 of our vehicles myself and during the process I flushed many times first with distilled water. When I added concentrated coolant I was concerned about making sure I had correct protection for the engine. I tested quickly with this refractor and it indicated I had adequate mixture. I then would test it with only water and it would calibrate down to 32 degrees as freeze point. I’m hopeful this is accurate but it seems very nice!

Pros

Easy to read the scale when held under light.

Cons

Some models may be bulky or heavy
