KGD - WQ - 533 Series NDUV Ultraviolet Ultra - Low Range Gas Sensor Module

KGD - WQ - 533 Series NDUV Ultraviolet Ultra - low Range Gas Sensor Module

Product Introduction

The KGD - WQ - 533 series NDUV ultraviolet ultra - low range gas sensor module adopts the Non - Dispersive Ultraviolet Absorption (NDUV) technology. The ultraviolet light beam passes through the measuring gas chamber and is absorbed and attenuated. Then, the concentration of the measured gas is calculated based on the absorption relationship of the Lambert - Beer law. This product uses a highly stable ultraviolet light source and, through a unique optical path design, can directly measure NO₂ gas without a converter furnace, featuring high measurement accuracy, strong stability, and being unaffected by the conversion efficiency of the converter furnace.

Product Features

• Adopts a highly stable ultraviolet light source, with high precision and being unaffected by moisture.
• Directly measures NO₂, eliminating the need for an NOₓ converter.
• Automatic constant - temperature heating, with temperature and pressure correction.
• The sensor has a modular design, facilitating integration.
