Opus 20 Datalogger TCO
Datalogger for Temperature, RH, and CO2.

Lufft offers a variety of models with internal or external sensors for recording humidity, temperature, pressure and CO2.

For climate monitoring and recording in buildings, air conditioning units, laboratory, cleanroom, storerooms and museums, alarm indication (current or historical since the last data transmission), conversion of the display from %RH to absolute humidity or dewpoint with SmartGraph professional software.

A high level of CO2 in the air within a room causes headaches, tiredness and lack of concentration. The regulation on CO2 concentration was established in order to evaluate IAQ (Indoor Air Quality). As a guideline for school rooms in the USA the limit of 1,000 ppm applies; for workplaces the occupational exposure limit is 5,000 ppm.
