Rotronic CL11 Indoor Air Quality Data Logger

The Rotronic CL11 benchtop display unit is the latest development of an inexpensive multimeter which simultaneously measures and records CO2, humidity and temperature. It is equipped with the field-tested Rotronic Hygromer® IN-1 humidity sensor. Using the Rotronic software package SW2.x (supplied/downloadable), it can easily be set to record as required and data can then be downloaded, saved and analyzed. Power supply is by AA (x4) batteries.

Rotronic Instruments Data Logger

The Rotronic Instruments C11 data logger evaluates air quality with the combined measurements of CO2, humidity, and temperature. A high concentration of carbon dioxide can develop quickly when closed rooms with insufficient ventilation are filled with people. Carbon dioxide (CO2) is a colourless and odourless gas that exists in the earth’s atmosphere and which is dangerous in high concentrations. The proportion of CO2 in natural ambient air is about 0.04 % or 400 ppm. Exhaled air contains approximately 3.8 % by volume CO2, which quickly mixes with the ambient air. When closed rooms are insufficiently ventilated, the levels of CO2 increase quickly leading to fatigue and loss of concentration for the room's occupants. To initiate improvements to the air quality, for example by increasing the supply of fresh air, it is important to measure the key parameters of indoor air quality. These parameters are CO2, humidity, and temperature.
It has ROTRONIC HYGROMER® IN-1 humidity sensor that gives calibration at 35/80 %RH. This logger includes software for configuration and data download.
