The CI 21 transmitter is designed to provide low maintenance ammonia detection. With CI 21 technology, sensor life is no longer limited to ammonia exposure levels. This reduces replacement costs associated with electrochemical sensors. Features include: stable long-life charge-carrier injection sensor; sensor is unaffected by exposure to high gas concentrations; low temperature operation to -40°F; low cross-sensitivity; eliminates costly false alarms; and low cost of ownership.
