PORTABLE IAQ METER
CO2+RH+TEMP.
IAQ METER/LOGGER
INTRODUCTION
Thank you for purchasing this portable
IAQ meter. The meter measures CO
level, air temp., dew point, wet bulb temp.
and humidity and is an ideal instrument for
indoor air quality (IAQ) diagnosis.
Poor indoor air quality is considered
unhealthy because it causes tiredness,
loss of ability to concentrate, and even
illness(ex. Sick Building Syndrome). IAQ
monitoring and survey, especially on CO
level and air ventilation become widely
applied in public areas such as offices,
classrooms, factories, hospitals and
hotels. It is also suggested in regulations
of industrial hygiene in some countries.

The portable CO meter uses NDIR (non-
2
dispersive infrared) technology to ensure
the reliability and long term stability. It’s
useful in verifying HVAC system performance and air ventilation control.

POWER SUPPLY
The meter is powered by either 4 AA
batteries or a DC adaptor(5V/1A output).
Install the batteries into the battery
compartment on the bottom and make
sure they are in correct polarity and good
contact.
cut off the power supply from batteries.
The adaptor can’t be used as a battery
charger.
When battery voltage gets low,
appear on the LCD .
The CO sensor can’t work normally
under low voltage, please replace with
fresh b ies or connect with an
adaptor.
When an adaptor is used, it will

SET
At power up, it emits a short beep and
performs 30 seconds countdown(Fig.2)
for meter warm up, then enters normal
mode with current CO and real time
displayed (Fig.3). The real time display

Suggest to wait for 30 seconds warm up
time. For quick start, you may press

for 2 seconds to end the warm up
and entering normal display.
TAKING MEASUREMENT
The meter starts measurement when
power on and update readings every
second. In the condition of operating
environment change (ex. from high to
low temp.), it takes 30 sec to respond
for CO sensor and 30 minutes for RH.
