Read and analyze the data using computer or cellphone. Achieve multi-parameter and all-direction
real-time monitoring and assessment of indoor air quality, and use it to control building ventilation and air conditioning system, etc.

Rigorous design, professional test and calibration for the commercial grade indoor air quality detector.
High performance with REST and WELL/LEAD Certificate, able to replace expensive professional instrument, coordinate well with data collection and analysis system, make multipoint real time monitoring placement easy to achiece
Sutiable for smart building, smart home system, air quality data collection system, green building evaluation system, ventilation system.

Features

24-hour online real-time detecting indoor air quality, upload measurment data.
The special and core mulit-sensor module is inside, which is designed for the commercial grade monitors. The whole sealed case aluminum structure ensures the stability of detection and improves the anti-jamming capability.
Unlike other particle sensors, with a built-in large flow bearing blower and the control technology of automatic constant flow, MSD has the much higer and long-term operation stability and life, of course more accuracy.
Providing multiple sensors such as PM2.5, PM10, CO2, TVOC, HCHO, temperature and humidity.
Using own patent technologies to minimize the influence form ambiance temperature and humidity to measured values.
Two power supply selectable: 18~2VDC or 100~240VAC
Communication interface is optional: RS485 Modbus, WIFI, RJ45 Ethernet.
Supply an extension TTL/RS485 port for preset or correction the measurements.
Three-colour ligh ring indicating different level of indoor air quality; the ligh ring can be turned off.
Ceiling munting and wall mounting with the tasteful appearance in different decoration styles.
Simple structure and installation, make even ceiling mounting easy and convenient.
RESET certified as the grade B monitor for Green Building Assessment and Certification.
Over 12-year experience in IAQ product design and production, abundantly applied in European and American market, mature technology, good manufacturing practie and high quality ensured.
