Products | KET-THL-305

Wireless temperature, relative humidity and light probe

The KET-THL-305 environmental sensor is designed for the accurate measurement of key microclimatic parameters essential for environmental comfort and energy efficiency in buildings. Through the precise detection of temperature and relative humidity, along with the dual measurement of ambient light, the device enables optimal comfort regulation and a consequent reduction in energy consumption.

The KET-THL-305.DY version, equipped with a zero-power e-ink display, provides users with detailed information on the level of thermal comfort present in the environment, ensuring a clear and continuous reading of the detected parameters with minimal impact on energy consumption.

The KET-THL-305.TS version introduces the functionality to set the desired comfort level, offering personalized control over environmental conditions.

Designed for easy integration into building management and energy management systems (BMS / BEMS), the environmental sensor provides a simple user interface manageable remotely, optimizing the monitoring and control of environments. Designed for professional use, it supports remote or local firmware updates, ensuring its constant efficiency and functionality over time. For applications in public environments, it offers a keypad lock and limitation of active functions, ensuring controlled and safe use.
