DESCRIPTION:
The Extech CO260 is a handheld indoor air quality CO/CO datalogging meter engineered for comprehensive monitoring of indoor environments. It simultaneously measures carbon monoxide and carbon dioxide concentrations, ambient temperature, and relative humidity, and calculates dew point and wet bulb temperatures — all visible on a large backlit LCD with real-time clock. The CO260 includes a maintenance-free NDIR CO sensor, programmable CO warning with audible alarm, and USB interface with PC software for in-depth data analysis and continuous datalogging up to 32,000 readings. Users can manually store up to 99 readings in internal memory, and additional functions include MIN/MAX, data hold, auto power-off with disable, and pressure compensation for CO measurements at different altitudes.
