GCS515A AMMONIA DETECTOR

The GCS515A Ammonia Detector is based on Charged Carrier Injection cell, which is able to operate in a wide range of temperatures (-45°F to 140°F). The unit is also able to withstand wide humidity situations, from 0 – 99% relative humidity. Charged carrier injection, combining the advantages of electrochemical and chemosorption cells, also eliminates the possibility of false alarms associated with metal-oxide sensors when alcohol, cleaning agents, water, carbon monoxide, and many other interferences. This long-lasting cell is capable of lasting 4-5 years without replacement, twice as long as some other types of cells. The unit is capable of 0-200 ppm detection. The 4-20mA output signal can be connected to the dedicated GCS530/540 alarm displays or alternatively can be connected to GCS2xx digital display/controllers or to independent PLC systems.
