UK Clairair infrared gas sensor - S509-CH4
High-precision measurement over a wide operating temperature range of -40°C to +70°C
The sensor automatically corrects drift and adjusts the zero point automatically.
Immune to toxic and harmful substances, with anti-poisoning capability.
It can operate in high-humidity environments.
It uses the non-dispersive infrared principle and has a long service life.
While the sensor is operating, it outputs both digital and analog signals simultaneously.
It features a standard interface output, and the peripheral circuit is simple to use.
