CO & NO2 Sensor TG Series

CO & NO2 Sensor

 

The Senva TG CO & NO2 Sensor Series can be ordered as individual CO or NO2 sensors or as a combination CO/NO2 sensor in a shared enclosure. Sensor features 2 outputs that support daisy chain wiring. The unit can act as a stand along controller, utilizing the relay for exhaust fan operation or the output for direct control or a VFD. Multiple sensors may be used in a parallel sequence (0-10V) for cost effective coverage of large areas.. Kele is the leading supplier of building automation products. When you need the right product, right now, count on Kele.
