CO2, TEMPERATURE AND HUMIDITY METER ST802
Our indoor air quality meters can measure at the same time the levels of (Carbon Dioxide CO2, Temperature ºC and Relative Humidity %RH). Highly reliable and accurate equipment, equipped with a NDIR detector (non-dispersive IR technology), compact and easy to use, in desktop or portable formats, with alarms when a set level is reached. Control CO2 levels in schools, offices, greenhouses, factories, hotels, hospitals, transport, etc... with total guarantee.
