exhalation affects CO2 levels.
• Do not calibrate the meter in the air with
unknown CO2 concentration. Otherwise, it will
be calibrated as 400ppm by default and leads to
inaccurate measurements.

INTRODUCTION
Thank you for purchasing this portable CO2 meter. The
meter measures CO2 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 CO2 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. (Appendix)
The portable CO2 meter uses NDIR (non-dispersive
infrared) technology to ensure the reliability and long
term stability. It’s useful in verifying HVAC system
performance and air ventilation control
Features
• Triple displays of CO2 level, temp. and humidity.
• Stable NDIR sensor for CO2 detection.
• Statistics of weighted averages (TWA & STEL)
• Backlight for working in dark area
• Audile CO2 warning alarm
• Battery and adaptor power supply
• Easy manual calibration on CO2 and humidity
• USB PC connection

OPERATION
1. Press “POWER/SET” to turn instrument on and off.
At power up, it emits a short beep and performs
30 seconds countdown for meter warm up, then
enters normal mode.
2. 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 CO2 sensor and 30 minutes for RH.
3. Press “DP/WBT” to switch temperatures
display. The lower left display will cycle from air
temperature, dew point temp., and wet bulb
temp. (Fig.1)
Fig.1
4. Press “HOLD” to freeze the readings, “HOLD”
icon is displayed on the left top of LCD. All current
readings are kept unchanged, except STEL and
TWA. Press “HOLD” again to cancel data hold
function.
5. Hold down “MODE/p”for more than 1 second to
activate and cancel backlight.
6. Press “MAX/MIN” to see the minimum, maximum,
and weighted average readings. Each press of it
displays MIN, MAX, STEL, TWA in sequence and
returns to normal mode. In MIN and MAX modes,
it shows the minimum and maximum readings
of CO2 on main display, and of AIR/DP/WBT
temperatures and humidity on the lower displays.
