Refractometer

[DavidC]

Anyone here using a refractometer to test anti freeze?. If so, which brand and how do you like it. I am thinking about getting one and there appears to be many around with prices I have seen from 19. 00 to at least 900. 00. Your thoughts please.

David,

Have a look at this thread, Bill R decided to order a refractometer to test his Cat Coolant.

I'm sure he will tell you where he got his. You can PM him or wait until he sees this thread.

Thanks Mike. I seem to remember at least one other post on these so I tried a search and came up dry for some reason so I figured I would just ask. After all I am not competing with the "whats the best oil threads". The post I remember I thought had this link

Refractometer - Best Means for Testing Ethylene Glycol & Propylene Glyc

Looks like 150. 00 and has temp compensation built in. I don't mind paying for a good test instrument but I would also like other peoples thoughts if they have/use one.

Got mine at ebay. Focus in the eyepiece and it works good. Note amount sold. Accurate enough for coolant/antifreeze testing.

Post Script: There are a bunch of the same model. You may be able to get it cheaper.

We use them in our business to measure specific gravity, you can buy them cheap as posted on e-bay. Calibrate with distilled or DI water first to be accurate
