Indoor Air Quality 

Monitor & Data Logger

 

M9-IAQS

M9-IAQS

 is an indoor air quality controller with screen provides customers with visual indoor air quality readings, 

such as PM2.5, CO2, temperature, humidity, etc.; It can control the HVAC system directly. For example: Adjust the 
fan speed, control air supply / exhaust

set mode and other functions. It is widely used in residential, commercial 

and  industrial  applications,  and  can  effectively  improve  air  quality  and  create  a  healthy,  comfortable, 
efficient, environmentally friendly, energy-saving living and working environment. 

Compatible with embedded and wall-mounted fixing methods;

Compatible with push-button and touch-screen operation;

Using standard 86 box size, thickness <24mm;

PM2.5, CO2, RH&T etc., multiple sensors can be optionally selected.

With fresh air control function, three level speed of wind can be adjusted, four working modes: intelligent,

manual, mute, and periods.

Customizable filter alert function.

 

The  built-in  dust  sensor  uses  the  principle  of  laser  scattering  technology  to  detect  the  indoor  PM2.5  mass

concentration in real time

μg/m³

;

The built-in carbon dioxide sensor uses the principle of NDIR technology to detect indoor CO2 concentration in real

time (ppm);

The RH&T sensor use capacitor resistance material to detect the indoor temperature (° C) and humidity (%) in real

time.

Applications 

Residential ventilation system

Business ventilation system

Industrial ventilation system
