About this item
The charge carrier injection (CI 21) sensor is a progressive development to improve upon current ammonia refrigeration detection methods.
- Stable, long-life charge carrier injection sensor
- Sensor is unaffected by exposure to high concentrations of ammonia (NH₃) gas
- Low temperature operation –40 °F
- Compact design
- Low cross-sensitivity compared to MOS sensors
- Low cost of ownership
With CI 21 technology sensor life is no longer limited to ammonia exposure levels. It is unaffected by exposure to high gas concentrations. 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, long-term safety.
The CI 21 transmitter is an advanced development to which all other ammonia transmitters will be compared.
