Description
The HUMLOG20 facilitates exact and professional recordings for climatic measurements of humidity, temperature, and CO2 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 straightforward 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.
