Extech CO260 C02 monitor


The Extech CO260 CO2 monitor measures indoor air quality for Carbon Monoxide (CO) and Carbon Dioxide (CO₂) levels.

The Extech CO260 CO2 monitor measures indoor air quality for Carbon Monoxide (CO) and Carbon Dioxide (CO₂) levels. In high concentrations these gases can affect the health and well-being of people and pets. Monitor CO₂ levels in schools, office buildings, greenhouses, factories, hotels, hospitals, transportation lines and anywhere that high levels of carbon dioxide are generated. Common areas to monitor CO levels include boiler rooms, warehouses that use propane and gasoline-powered for lifts, boats, planes, RVs, and manufacturing plants. The Extech CO260 CO2 monitor also measures air temperature/relative humidity and calculates dew point/wet bulb temperatures. The Extech CO260 CO2 monitor can data log manually up to 99 readings with internal memory or continuously up to 32K readings with included software.
