Introduction
Thank you for selecting the Extech CO260 Meter. The CO260 measures CO
2
(Carbon Dioxide)
levels, CO (Carbon Monoxide) levels, air temperature, and relative humidity. The CO260 also
displays dew point and wet bulb temperatures, generated from calculations performed on
temperature and humidity measurements. The CO260 is an ideal instrument for indoor air
quality (IAQ) analysis.
This device is shipped fully tested and calibrated and, with proper use, will provide years of
reliable service. Please visit our website (www.extech.com) to check for the latest version and

Safety Information
IMPORTANT CARBON MONOXIDE (CO) SAFETY
NOTES
•
The CO260 Carbon Monoxide Monitor is intended for general purpose Air Quality monitoring
only, and has not been certified for use pursuant to any state or city safety Carbon Monoxide
Alarm or Monitoring requirements.
•
The CO260 Carbon Monoxide Monitor has not been tested by an independent lab to comply
with the UL 2034 or IAS 6-96 standard.
•
It is the responsibility of the customer to obtain and apply current local, state, and national
regulations with regard to CO alarms, monitoring and testing.
•
Electromagnetic (EMI) interference my cause erratic meter readings; do not place meter near
areas of high EMI when taking CO measurements.
•
Recovery time is required after the meter has been exposed to high levels of CO; the longer
the exposure, the longer the recovery time.
Carbon monoxide is life threatening even at relatively low concentrations; learn
and recognize the effects of CO poisoning (see Table below). Do not use this
meter as a personal safety-monitoring device.
