Refractometer

[noo2usa]

How do I calibrate my refractometer? It's brand new and I know it's reading high. Is there a solution or onother way to pin point the specific gravity so I can set it to read properly?

Just make sure you close it after every use, because any small amount of evaporation can throw off the solution.

Also it doesn't say in the description, but the solution is 35ppt, AKA 1.026

Are the $40 house brand refractometers as accurate and easy to read as the more expensive ones? Online Reviews vary.

Thats what I use. I calibrate it every 6 months but it has never been out of cal. I got mine from Bulk Reef Supply.
