Analygas® Systems Model 22 is a wall mounted gas monitor for use in non-hazardous indoor locations.  It is housed in a rugged steel enclosure.

The electrochemical sensor in this instrument is specific to the target gas and minimizes the chance of false alarms from interfering gases or vapours.

The front panel digital display indicates gas concentration. Optionally, the display is available separately for remote mounting.

A 4-20mA output is included for data logging, computer processing, etc.

Dry contact relays are included to activate

ventilation fans or permit control of other auxiliary equipment.

Electronic timers delay the alarm action of relays which reduce unnecessary run times of exhaust fans. This cuts plant operating costs and reduces wear and tear on external controls.

This unit is ideal for use in ice rinks, small garages, chlorination rooms, ammonia plants, etc.
