CO2 Data Logger CL11

CO2 data logger, measurement of CO2, temperature and humidity in rooms, with display and alarms, for better air quality

Description

The CL11 benchtop display unit is an inexpensive multiple parameter data logger that simultaneously measures and records CO2, humidity and temperature. Using the software package SW21, it can be easily set to record as required and data can then be downloaded, saved and analyzed.

A value of 1 000 ppm is considered to be hygienically harmless whereas between 1 000 and 2 000 ppm, ventilation is recommended and over 2 000 ppm, ventilation is required. Of course, lower values should be aimed at, taking into account that the outside air already contains 350 ppm to 440 ppm of carbon dioxide.
