Product specification

When it comes to temperature, the wireless thermometer TRIO from TFA informs you 3-fold:
A separate wireless transmitter determines the outdoor temperature at the location; an internal sensor measures the indoor temperature. A supplied radio transmitter can be used to determine the temperature outside or in another room. The second transmitter has a waterproof cable transmitter and it’s thus ideal for temperature control in the refrigerator, the aquarium, pool or pond. The maximum and minimum values are permanently displayed for all temperature values.
Controlling the room temperature is an important factor for the creation of a comfortable and healthy living environment and it helps save energy. Even one degree of temperature reduction can save up to 6% on heating costs.
With the outdoor temperature, you get reliable and important information for your home, garden, leisure and work.
Up to 8 transmitters can be connected to the device altogether.
