Pfaudler - Model Type 40 -pH Probe

The pH sensor type 40 changes the nature of pH measurement by eliminating the need for internal electrolyte solutions and reference junctions. This design virtually eliminates the problems caused by ageing and pollution of the reference sensor. This pH-measurement principle is called relative pH-measurement.  The probes design and the rugged Pfaudler Glasteel™ surface allows them to be directly installed into the process (product flow), thus detecting the pH immediately and directly, without a protective cage.  The pH probe type 40 is available in a rod and a ring design. Alternatively, the smaller pH probe type 18 can be used.
