pH/ORP Sensor Part Numbers
Part Number Description:
First Location = Sensor type, i.e. P = pH, or O = ORP
Second Location = Monitor/controller model, i.e. 7 = 720II
Third location = Sensor size, i.e. 2 = 1/2” MNPT or 4 = 3/4” MNPT
Fourth location = Sensor option, i.e. S = Single Junction, D = Double Junction, LC = Low Conductivity, or F = Flat.
Size Single Junction Double Junction Low Conductivity Heavy Duty Flat Tip
