Product Details
Greenhouse Gas Sensor KGD-GAS-212
Product Introduction
The Greenhouse Gas Sensor KGD-GAS-212 is based on the infrared gas
sensor technology (NDIR). It adopts a high-performance probe, a gas
chamber processed by a special technique, and a built-in constant
temperature treatment design. It has the characteristics of high
precision, small drift, and fast response, and can adapt to changes
in different temperatures. It is especially suitable for occasions
where the background gas for detection is complex and precise
detection is required.
Product Features
- High precision, with a linear error of less than 1%F.S.
- Constant temperature control to reduce the influence of ambient
temperature and with strong stability
- Optimally selected absorption peaks and interference compensation
algorithms, with little cross-interference
- Modular design, facilitating integration
