DM502-O3 7-In-1  0-5PPM PM2.5 PM1.0 PM10 Temperature Humidity TVOC Air Quality Monitor Ozone Detectoror

 

Description:
DM502-O3 monitor is an intrinsically safe gas detector developed by our company for environments containing ozone gas. The detector uses natural diffusion. The gas is detected by an electrochemical gas sensor, which has excellent sensitivity and excellent repeatability.
 
This O3 detector is ideal for health, environmental, industrial and residential monitoring. Useful for detection of ozone residue after disinfection.

Our DM502-O3 is easy to use and maintain, and meets the requirements of industrial field safety monitoring for high reliability of the equipment. The shell is made of high-strength engineering plastic. It has high strength and good hand feel.

Features:
- Laser sensor for PM2.5 to detect dust Smog.
- Electrochemistry sensor for O3.
- Semiconductor sensor for TVOC.
- Temperature and Humidity sensor.
- AQI for Integrated air quality index.
- Support time and date, self-calibration function.

Application:
1. Air quality monitoring
2. Industrial safety
3. Air purification control
