Features

Designed for real time detecting carbon dioxide, air quality, temperature or relative humidity in air ducts.
NDIR infrared CO2 sensor inside with special Self Calibration and up to 15 years’ lifetime. It makes CO2 measurement more accurate and reliable.
Mix gases sensor with high sensitivity for VOCs from new furnitures, wall coverings, office equipment, cleanser etc. and other pollutants from smoking and cocking etc.
Combined temperature and humidity digital sensor provides a high accuracy measurement in full range.
Provide up to 3 analog outputs (0~10VDC or 4~20mA or 0~5VDC) for CO2, air quality (VOC) and temperature or relative humidity.
Modbus RS485 interface with outputs for CO2, temperature, humidity and air quality (VOC).
With LCD or without LCD selectable
LCD display real-time measurements of CO2, air quality (VOC), temperature and relative humidity.
Simple and smart design and installation of sensor probe with a water-proof and porous film
Extendable probe meets more air duct systems
24VAC/VDC power supply.
EU standard and CE-approval.

Application

Residential houses, exhibition halls, restaurants, shopping malls, sports gymnasiums, conference rooms, etc.
Museums, theaters, offices, classrooms, train stataions, airports, etc.
