KGD-WQ-529 Micro-flow Infrared Gas Sensor Module with Dual-gas-chamber Design for 0-4000ppm NO Detection
The KGD - WQ - 529 series micro - flow low - range infrared gas sensor module adopts micro - flow infrared dual - gas - chamber sensor technology. The gas chamber consists of a measured gas chamber and a reference gas chamber. After the infrared light source irradiates the measured gas and the reference gas respectively, the signal waveforms formed in the micro - flow infrared sensor are processed by the signal processing system, and the concentration of the measured gas is obtained through the ratio. The KGD - WQ - 529 adopts a dual - gas - chamber structure and a special filter, which solves problems such as environmental temperature instability and aging of electronic components. It improves the accuracy, stability, and anti - interference ability of measurement results, enabling ultra - low - range gas measurement.
- Micro - flow infrared sensor technology.
- The gas chamber adopts a dual - chamber design of measurement and reference, with high accuracy.
- Modular sensor design for easy integration.
- Automatic temperature and pressure compensation.
