The temperature and humidity measurement unit is imported from Switzerland, ensuring accurate measurement;
 

PM2.5 and PM10 are collected simultaneously, with a range of 0-1000μg/m³ and a resolution of 1μg/m³. The unique dual-frequency data acquisition and automatic calibration technology ensures consistency of up to ±10%;
 

The gas unit uses an electrochemical sensor, which has excellent sensitivity and repeatability;
 

The air pressure range is a wide range of 0-120kPa, which can be applied to various altitudes;
 

The TVOC measurement unit adopts imported high-sensitivity gas detection probes from abroad, with mature technology, and uses high-performance signal acquisition circuits, ensuring stable signals and high accuracy.
