NDUV Gas Sensor Module with 0-1000ppm NO₂ Range RS-232 Communication and T90 ≤ 4.5s Response Time
The KGD - YQ - 537 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 cell and is absorbed and attenuated. Then, the concentration of the measured gas is calculated according to the absorption relationship of Lambert - Beer's law. The 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 not being affected by the conversion efficiency of the converter furnace.
- Using a highly stable ultraviolet light source, with high precision and not affected by moisture.
- Directly measures NO₂ without the need for a NOₓ converter.
- Automatic constant - temperature heating, with temperature and pressure correction.
- Modular design of the sensor, easy for integration.
