Rotronic CL11 CO2 Gas Measurement Data Logger Instrument (Benchtop)

Rotronic CL11 CO2 gas meausrement data logger is a carbon dioxide measurement instrument and indoor air quality (IAQ) monitor capable of multi parameter measurement.

Equipped with the field tested Rotronic Hygromer IN-1, the CL11 simultaneously measures and records CO2, humidity and temperature.

Using the ROTRONIC software package SW21, the CL11 gas measurement data logger can be easily set to record as required and data can then be downloaded, saved and analysed.
