The Differential Difference
Do you ever tire of always replacing your pH sensor? Well there is an option for you: the differential pH sensor!
Differential measurement technology uses two glass electrodes to make the measurement differentially with respect to a third metal electrode. The resulting true differential measurement has several advantages over conventional sensors: ground loop problems are virtually eliminated and the sensor can be restored to factory condition at modest cost by replacing the salt bridge and reference solution.
The replaceable salt bridge is SIMPLE – no special tools are required! Just grab a #3 Philips screwdriver or 1/2” wrench and rejuvenate your sensor in seconds.
The probe lasts for years, not months!
