HUMLOG20
The HUMLOG20 facilitates exact and professional recordings for cli-
matic measurements of humidity, temperature, air pressure and CO
2
concentration.
The long battery life and large memory allow for continuous data
recording over long periods of time. The configuration of the data logger
and the evaluation of the measurement data are simple and straightfor-
ward using SmartGraph3 software, which is included in the scope of
supply. The built-in Ethernet interface makes the HUMLOG20 Network
capable, and ensures maximum reliability in data transmission.
For various requirements in the application, the four models THI, THIP,
TCO and E are available. The Model E offers the highest flexibility with
analog and digital interface for external sensors.
