Product Details
Miniature Infrared Carbon Dioxide Sensor KGD-SRH-210
Product Introduction
The Miniature Infrared Carbon Dioxide Sensor KGD-SRH-210 is an
industrial-grade gas sensor used for real-time measurement of
changes in gas concentration. It adopts the infrared gas sensor
technology (NDIR). Compared with the thermal catalytic and
semiconductor principles, it has remarkable features and advantages
such as a good signal-to-noise ratio, strong selectivity, immunity
to cross-gas interference, high precision, excellent long-term
stability, and a long service life. It meets various usage
requirements in industrial sites, laboratory measurements, etc.
Product Features
- Ensures detection accuracy across the entire temperature and
concentration range
- Multiple measurement ranges are optional, full-range linearization,
and digital output
- Fast response, good stability, dustproof and waterproof with an
IP64 rating
- Abnormal alarm outputs such as high humidity alarms
- Meets the explosion-proof rating of Ex ia IIC T4 Ga, and the
explosion-proof certificate number is CITCEx21.0902U
