CO2 Display for Indoor Air Quality Monitoring


The CO2 Wall or Desktop Display is the latest development in a line of cost-effective instruments that simultaneously measure and record CO2, humidity and temperature. Equipped with the ROTRONIC HYGROMER® IN-1 sensing element, which has proven itself over many years, this measuring device offers an unrivaled price/performance ratio. The device can be configured directly via its side keys and the recorded data can be downloaded to a USB stick for analysis with the free software from ROTRONIC.
