Wireless temperature, relative humidity and light probe
The KET-THL-300 room probe measures the main parameters useful to evaluate the microclimatic conditions that guarantee people's comfort. The precise measurement of temperature and relative humidity together with the double measurement of ambient brightness allow perfect adjustment of comfort and a simultaneous reduction in consumption.
The .DY version with display offers users a lot of information on the degree of thermal comfort present in the environment. The innovative zero-consumption e-ink display guarantees excellent readability and allows continuous display of the parameters.
The .TS version allows the user to set the desired degree of comfort.
Designed to easily integrate into supervision and energy management systems (BMS / BEMS) it provides a simple user interface that can be managed remotely. Designed for professional use, it supports firmware updating remotely or locally and rapid charging or battery replacement during service. Suitable for use in public environments supports keyboard lock and limitation of active functions.
