Infrared Gas Sensor Module KGD - YQ - 531

Product Introduction

The KGD - YQ - 531 is a high - performance infrared gas analysis sensor module independently developed. Based on the principle of non - dispersive infrared (NDIR) technology, the product adopts the gas filter correlation infrared (GFC) absorption method. By comparing the absorption degrees of the sample gas and the reference gas, it calculates the concentration of the measured gas according to the absorption relationship of Lambert - Beer's law, and effectively eliminates the detection error caused by gas interference through the reference gas cell.

The product uses a reliable and stable light source, a high - performance detector, and a precise signal processing circuit, and has the advantages of high measurement accuracy, strong anti - interference ability, and long - term stable use. It is especially suitable for working conditions where the gas concentration is low, the absorption is weak, and long - term monitoring is required.

Product Features

Suitable for measuring ultra - low concentration gases, and can detect CO gas below 0 - 50ppm.

The energy difference received by the detector is only related to the concentration of the measured gas, with good anti - interference performance.

Long - life light source and reliable filter gas sealing technology can meet the requirement of long - term stable operation.

Less affected by the external environment, no need for frequent calibration.

Constant temperature control, with small drift and high stability.

Independent gas detection module, easy for integration and application.
