Product Description
M4 Knick Type 18 Differential pH Sensor
The Type 18 uses a differential measurement design and rugged Glasteel construction for aggressive liquids. It can measure pH or pH-compensated ORP, depending on configuration.
Unlike conventional reference-electrode designs, it does not require an internal electrolyte reservoir or a reference junction. This avoids maintenance associated with electrolyte depletion and junction fouling. The sensor can be installed in different orientations and calibrated at a single point in the process without removal.
