CO2 – Measurement and Monitoring of Carbon Dioxide in Rooms

CO2 Display

The wall-mounted or bench-top CO2 display is the latest development of an inexpensive display unit that simultaneously measures and records CO2, humidity and temperature. Equipped with the field-tested ROTRONIC HYGROMER® IN-1 humidity sensor, this instrument offers unbeatable value for money. The instrument can be configured directly with buttons and stored data can be exported to a USB stick for analysis with the free ROTRONIC software package SW21.
