Product specification

With TRINITY wireless thermo-hygrometer, you can simultaneously monitor the room climate at the installation site and the temperature and humidity in the open air via the wireless transmitter.
The outdoor values are sent to the station and you’re always well-informed on the weather developments.
Controlling the indoor temperature and humidity through targeted heating and ventilation creates a comfortable and healthy living environment and even saves on heating costs. The ideal is a indoor temperature of 18 ° C to 22 ° C and a relative humidity of 40 to 60%.
Instead of the outdoor area, you can install the wireless transmitter in other distant rooms (nursery, basement, storage room, conservatory, greenhouse) and measure the indoor climate there as well.
In addition, this practical device displays the exact time in large format. The weekday is shown above the date.
