Description

The sensor consist of a probe to which is tted 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 sup-

plied 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 otation mounting assembly is

fully adjustable for sensor placement (P/N MHBF). Its ota-

tion 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 ac-

tion scrubbing is not required, an economical xed submer-

sion mounting assembly is available (P/N MHDS).
