PH4P
PH4P Polymer Electrolyte pH Sensor
- Allows pH measurement under severe conditions, such as where the process fluid is heavily contaminated or contains sulfide.
- With polymer used as the inner solution, the liquid junction is large (1.0 mm to 1.5 mm), and there are 2 single pores, which prevent clogging.
Specifications
