| This reduces replacement costs associated with electrochemical sensors. |
| The Charge Carrier Injection Sensor is a progressive development to improve upon the current ammonia refrigeration detection methods. With this technology the life of our sensor is no longer limited to the ammonia exposure levels. This reduces replacement costs associated with electrochemical sensors. The 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 transmitter is an advanced development to which all other ammonia transmitters will be compared. |
