Extech CO260 Indoor Air Quality Meter and Datalogger

The Extech CO260 Indoor Air Quality Meter and Datalogger delivers professional-grade monitoring of both carbon monoxide (CO) and carbon dioxide (CO2) in indoor environments. Engineered for HVAC specialists, environmental inspectors, and facility managers, this meter provides fast, accurate readings to help assess ventilation efficiency and overall air safety.

Featuring a bright backlit LCD with a real-time clock, the CO260 displays CO and CO2 levels alongside temperature, humidity, dew point, and wet bulb measurements. The NDIR sensor offers maintenance-free CO2 detection, while the electrochemical sensor ensures precise CO monitoring.

Built for data reliability, the CO260 allows you to manually store up to 99 readings or continuously log up to 32,000 data points. USB connectivity and PC software enable detailed post-analysis. The unit also calculates statistical safety metrics including TWA and STEL, enhancing compliance with occupational health standards.
