CO

/TEMP/RH METER
_____________________________________________________________________________________________
INTRODUCTION
Thank you for purchasing this portable CO
2
meter. The meter measures CO
2
level, air temp.,
dew point, wet bulb temp. and humidity(DP, WB, RH are for model GT1060-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,
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 CO
2
level, temp. and humidity (GT1060 RH).
• Stable NDIR sensor for CO
2
detection
•
Statistics of weighted averages
TWA
(8 hours weighted average)
STEL
(15 minutes weighted average)
• Backlight for working in dark area
•
Audile CO
2
warning alarm
• Battery and adaptor power supply
•
Easy manual calibration on CO
2
and humidity (RH for GT1060 RH only)

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 batteries. The adaptor can’t be used as a battery charger.
When battery voltage gets low,
and “Lob” will appear on the LCD (Fig.1). And beeper sounds.
The CO
2
sensor can’t work under low voltage, so it beeps to indicate failed CO
2
measurement
(press any key but
to stop the beeps) and the readings won’t be displayed. Please
replace with fresh batteries or connect with an adaptor.
