Refractometer

[tahoe98]

I just ordered a refractometer from you guys and wondered if it needed any kind of calibration before I start using it. It is the one for like $40 and it came with a little screwdriver. I didn't know if or how I calibrate it. Thanks.

get some RO/DI water and see if it reads 0...If not adjust to same.

There are more accurate ways of doing it, however the RO/DI water as mentioned above will work just fine for you.

If you want to make your own solution do a search in the chemistry forum. Randy Farley has the recipe in there. HTH

use distilled water. You can get it from gas stations.
