Description

2211004 CI 21 Fixed Gas Transmitter with Internal Sensor, Ammonia (NH3), 0 to 200 ppm by GfG

The charge carrier injection (CI 21) sensor is a progressive development to improve upon current ammonia refrigeration detection methods. With CI 21 technology sensor life is no longer limited to ammonia exposure levels. This reduces replacement costs associated with electrochemical sensors.

Charge carrier injection technology also eliminates false alarms frequently associated with metal oxide sensing (MOS). These, along with other features, provide reliable, cost effective, longterm safety.

The CI 21 transmitter is an advanced development to which all other ammonia transmitters will be compared.

Stable long-life charge-carrierinjection sensor
Sensor is unaffected by exposure to high gas concentrations
Low temperature operation to -40oF
Low cross-sensitivity
Eliminates costly false alarms
Low cost of ownership
