Description

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.
Detection Focus
? Carbon Dioxide (CO2)
Indoor CO2 level is a universal accepted parameter for the condition of indoor ventilation and air quality.
A time period can be preset from 1 to 24 hours, e.g. 5 hours, then the monitor can display CO2 average level during
this period, which provides an objective and true data for the measurement of the air quality in a certain space.
? Non-dispersive infrared (NDIR) CO2 sensor with more than 10-year lifetime
? ABC self-calibration technology guarantees reliable CO2 measurement
? CO2 range: 0~2000ppm/0~5000ppm optional
? Rapid response, high stability and consistency
Air Quality (VOC)
The air quality sensor is a mix gases sensor with high sensitivity for VOC (kinds of volatile pollutant gases) such as ammonia, toluene, formaldehyde and cigarette smoke, alcohol, H2S, and carbon monoxide. So it is very suitable
