Rated 5 out of 5 by from An excellent pH controller This is a really nice pH controller. Very reliable, easy to use, great instructions, and many other cool features. I originally bought a pH controller from Cole-Parmer which really sucked. I decided to try this one and I'm very happy with my purchase! Thanks you Omega.

Rated 5 out of 5 by from Small, compact and accurate. I have a variety of Omega pH meters at my company. The quality is excellent. I have never been impressed with technical support though, at least in the pH meter area. The only downfall I see to this product is that there is not a dedicated, selectable option for one of the output relays for a failed pH probe like other, more expensive pH meters have.

Hi, My Name is Dee, our PH Controller is reading .8 lower than it should be. Do you have a document that shows how to re-calibrate our PH Controller Item# PHCN-37? Thank You Dee

Asked by: Dee4
We do have a full manual for the PHCN-37 pH controller that will assist you instead of the Quick Guide listed. Please email flow@omega.com and put in the subject line: PHCN-37 manual and can send that out quickly.
