Multi IAQ Monitor Operating Instructions
Model: ZGkb201
1. General Introduction
Indoor Air Quality is used to measure for the quality of air in interiors; the
comfortable indoor environmental quality can make people feel fresh, work
effectively and it’s good for the health. The CO2concentration is the important
factor of good indoor air quality. People breath in oxygen and breath out CO2,
nowadays people often close the windows to avoid noise and enjoy the
comfortable living and working environment provided by air-conditioning
systems, which results in the fact that the indoor concentration of CO2is far
higher than the outdoor average’s. With the high CO2concentration and non-
proper ventilation, people will feel headaches, dull, fatigued, lose of
concentration and correspond to the high levels of dust, chemicals and
bacteria in the air.
2. ZGkb201 ------ Multi IAQ Monitor (CO2 / Temperature / Humidity)
ZGkb201 Multi IAQ monitor is a cost-effective, air quality indicator, the large
single digit LED display with three most critical parameters of indoor air quality,
the current CO2concentration, the ambient temperature and the relative
humidity.
CO2-----CO2concentration indicates the amount of fresh air ventilation being
introduced to a space.
Ambient temperature----The suitable ambient temperature brings the
comfortable space.
Relative humidity----The relative humidity in air indicates the amount of
moisture.
Features:
NDIR (Non-Dispersive-Infrared) technology is being used to measure CO2
concentration up to 3000 ppm (parts per million)
The Large single digit LED clearly displays the CO2concentration,
Relative humidity and ambient temperature
The various (blue, yellow and red) colors of LED’s show the indoor air
quality situation
The Reliable CO2sensor provides the long-term calibration stability
Dimmer Function can automatically adjust the display of single digit LED
to reach the power saving
Benefits:
Enjoy the more comfortable, hygienic and healthier Indoor Air Quality
Save energy, get the proper ventilation, the over-ventilation of the building
can be reduced.
Improve the IAQ satisfaction in public.
Application:
ZGkb201 has the widely application for classroom, kindergarten, meeting room,
office building, shopping mall, theater, exhibition, hospital, hotel, sports center,
gymnasium, railway station, bus station, airport and other public place where
the comfortable and healthy indoor air quality is important.
3. LED Display
There are three modes: CO2, RH, Temperature measure mode.
CO2, RH, Temperature measure mode:
When CO2concentration is below
800ppm, the green LED will light.
When CO2 concentration is between
800ppm and 1200ppm, the yellow
LED will light.
When CO2 concentration exceeds
1200 ppm, the red LED will light.
When CO2concentration exceeds
the CO2measurement range
(0-3,000ppm), the CO2display
area will display with “Hi”. It will
disappear when the CO2
concentration returns to the
measurement range.
When RH exceeds the RH
measurement range 20%, the
humidity display area will display
with “Lo”. It will disappear when the
RH returns to the measurement
range.
When RH exceeds the RH
measurement range 90%, the
humidity display area will display
with “Hi”. It will disappear when the
RH returns to the measurement
range.
