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.

What is the output signal range? Do these sensors need an amplifier?

Asked by: KM913
Thank you for your inquiry. Unfortunately, pH/ORP probes have too high of an impedance and requires a transmitter such as PHTX-100 to convert to a suitable or usable signal output as a 4 to 20 mA.

Is there a warranty on these probes?

Asked by: Lab Scientist
Thank you for your inquiry. There is a 1 year warranty for this pH probe and also, please note that the shelf for all pH probes is 6 to 12 months.
