White ABS mini 3-in-1 air quality detector-PM2.5/real-time monitoring of temperature and humidity ｜Laser sensor + three-color over-standard alarm｜0-999µg/m3 range

Designed for home health!This white ABS mini 3-in-1 air quality detector integrates PM2.5, temperature and humidity monitoring. It is equipped with a high-precision laser sensor and an intelligent alarm system for wide-area measurement of 0-999µg/m3 to protect breathing safety in real time.The compact body + three-color dynamic display, the air quality is clear at a glance, and the standard is immediately warned to help you easily create a fresh living environment.

• 【Three-in-one accurate monitoring】
  
  
  Simultaneous detection of PM2.5 particulate matter concentration (0-999µg/m3), ambient temperature and humidity, the data is displayed on the same screen, and it is suitable for multiple scenes of home/office/travel.
• 【Laser sensing + active cycle】
  
  
  Built-in laser dust sensor and silent fan, active air circulation sampling, strong anti-interference, detection accuracy increased by 30%* (*Laboratory data).
• Three-color dynamic early warning system】
  
  
  The green/yellow/red three-color light ring changes with the PM2.5 concentration, intuitively feedback the air level; support custom alarm threshold (default 75µg/m3 trigger), sound and light dual reminders for more peace of mind.
• 【Portable design + long battery life】
  
  
  The mini body (palm size) is equipped with ABS fireproof material, anti-fall and wear-resistant; built-in rechargeable lithium battery, with a battery life of 8-12 hours at full charge, and can be used at will without restraint.
• 【Intelligent calibration + data lock】
  
  
  Automatically calibrate and return to zero at boot time to avoid errors; press and hold the HOLD button to freeze the current data for easy recording and comparative analysis.
