With LED narrowband light source and fast response photodiode (PD), the IR-B series NDIR gas sensor uses its fast response characteristics to achieve ultra-low power consumption, and is especially suitable for battery-powered portable and wireless gas detection equipment.
1. Ultra-low power consumption
2. Hardware resistance to water vapor interference
3. Quick response
4. Wide temperature industrial grade design

*1.The above parameters are measured in the laboratory at 25°C.
*2.The response time is measured under the conditions of configuring a hydrophobic membrane, a gas flow rate of 500ML/MIN, and using a common calibration gas chamber. The better gas path design can reach 7S, and the natural diffusion test is 13S. The response time will be affected if the explosion-proof disc is added or the design of the fixed chamber of the sensor is different, and a reference design can be provided.
