KGD-WQ-528 High Precision Fast Response NDIR Gas Sensor for Multi-Gas Measurement in Exhaust Analysis
KGD - WQ - 528 Infrared Exhaust Gas Sensor Module
Product Introduction
The KGD - WQ - 528 Infrared Exhaust Gas Sensor Module is based on non - dispersive infrared technology for gas concentration detection, featuring high precision and fast response. The product uses a multi-element combined measurement method, enabling simultaneous measurement of multiple gases. It has optimized interference compensation internally to avoid mutual interference among the measured gases. Combined with a microcontroller for processing, it performs functions such as gas sampling signal processing, sensor zero - adjustment, calibration, and result output. It realizes fast and accurate measurement of gases with multiple combined concentrations, meeting the requirements of automated measurement systems.
Product Features
- Adopts high - precision infrared dual - beam sensor technology, capable of measuring CO, CO₂, and HC.
- Equipped with O₂ and NO measurement interfaces, enabling integration with other exhaust gas analysis equipment.
- Automatic constant - temperature heating, temperature, and pressure correction.
- Modular sensor design for easy integration.
- Long service life, low cost, and high cost - performance ratio.
