P91 Dissolved Oxygen Probe

P91 Dissolved Oxygen Probe

The sensor consist of a probe to which is fitted a cartridge that contains a precisely stretched permeable membrane, electrodes and electrolyte (p/n P91D). The inexpensive cartridge will provide continuous service for 6 to 12 months and is the easily replaced in minutes. The cartridge is supplied hermetically sealed for longer shelf life. Featured in the system are optional mounting hardware assemblies that provide universal sensor mounting for all aeration basins. The unique flotation mounting assembly is fully adjustable for sensor placement (p/n MHBF). Its flotation ball design minimizes membrane fouling as the surface of the membrane is continuously scrubbed by wave action in the basin. For clean water applications where wave action scrubbing is not required, an economical fixed submersion mounting assembly is available (p/n MHDS).
