EVANS Analog Refractometer E2196 Designed to Accurately Test for Residual Water Content

I switched to Evans Waterless coolant and this is used to verify that you got all the water out. If you are going to switch from standard 50/50 coolant you should purchase this to test after the refill.

Works like it should to detect water in my Evans waterless coolant. Cost less than ordering from the Evans site.

I had to sent it to the company to get recalibrate. They did the calibration for free and sent it back. It works great now.

Quick and accurate.

It's a big help to have this tool when installing Evans coolant.

An absolutely necessary item if you're going to convert from normal coolant to this non water-based coolant from Evans. Worth the money to do it right. easy to follow instructions and it works very well.

Yes. This works great. I bought the more expensive "Evans" brand since I was using it to test their waterless coolant. It is actually the same brand sold elsewhere for much less, with an Evans sticker over the other brand name. The Evans sticker even has a clear background, so they aren't even trying to hide it.

Very easy to use and very helpful.
