1. This compact dust detector, with its small size and excellent precision detection capability, has become your reliable choice for maintaining air quality. It uses an advanced laser sensor to accurately measure the concentration of PM2.5 particles and dust in the air. Easy to operate with a simple interface, it starts with one press to display real-time PM2.5, temperature, and humidity data, allowing you to track air quality changes. Once exceeding the standard is detected, the device immediately alerts you to take prompt action to avoid risks. 2. Product dimensions: 70 x 70 x 32 mm 3. Product weight: 120 g 4.
