The Extech CO260 monitors 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 CO260 also measures air temperature/relative humidity and calculates dew point/wet bulb temperatures. It can datalog manually up to 99 readings with internal memory or continously up to 32K readings with included software.
