Hydride Gas Monitor -- Model CM98-411
Ammonia Gas Monitor -- Model CM99-447

The Ammonia and Hydride Gas Monitor is a continuous duty, low cost stationary monitor for detection fo Hydride or Ammonia gas. The monitor has a green LED indicating the unit is on and in a safe condition. A red LED will light when the unit is in alarm. The 1 amp relay will activate when the gas concentration exceeds 5 ppm Silane or 50 ppm Ammonia. This relay is latching which means tha the relay will stay activated until it is reset with the switch on the side of the monitor.

The monitor is an aluminum enclosure that is suitable for most applicaitons. Test connections and adjustment controls are located on the outside of the enclosure and are easily accessible.

The CM98-411 is designed to monitor for Silane in the range of 1-50 ppm with an alarm setpoint at 5 ppm Silane.

The CM99-447 is designed to monitor for Ammonia in the range of 1-200 ppm with an alarm setpoint at 50 ppm Ammonia. the alarm used in this unit is an electrochemical gas sensor.
