Introduction
Thank you for purchasing this portable CO
measures CO level, air temp., dew point, wet bulb temp. and
2
humidity (DP, WB, RH are for model version RH) 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, espe-
cially on CO level and air ventilation become widely applied in
2
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-dispersive infrared)
2
technology to ensure the reliability and long term stability. It's
useful in verifying HVAC system performance and air ventilation
control.

This package contains:
Meter, 4pcs AA batteries, Operation manual, Hard carrying case
Power supply
The meter is powered by either 4 AA batteries or a DC adaptor
(9V/1A output).
Install the batteries into the battery compartment on the rear
and make sure they are in correct polarity and good contact.
When an adaptor is used, it will cut off the power supply from
meter. The meter batteries. The adaptor can't be used as a battery charger.
