Gas Sensor with Display


Standard CO2 Sensor

The sensor design provides the foundation for gas detection systems that perform continuously with minimal maintenance. The sensors are rated for temperatures from -20  °C to + 40  °C and have excellent zero stability and high sensitivity. All sensors are close coupled to the transmitter for excellent noise immunity and the ability to transmit over long distances using two or three core shielded cable.Typical Oxygen Sensor Specification:
