Rated 5 out of 5 by from Great Gel Filled Electrode Bought this electrode for a replacement electrode for my 20 + year old PH meter no longer made. The electrode actually worked better than the original electrode when it was new with no span error from PH of 4 to PH of 7. Linearity was very good. Usually I had to tweak the cal pot a little on both ends of the range until the unit read both 4 and 7 PH but this was right on after initial adjustment.

Rated 4 out of 5 by from Helps our winemaking Just bought our third one. The previous one lasted 6 years. It only gets used for a couple of months each year. We have found it needs to be stored in a temperature controlled environment, or it will have a short life. Good results for the price.

Rated 5 out of 5 by from Great Price Great probe for the cost. I have been using these for several years now and they work & hold up well.
