Wireless thermometer RATIO
Always in the know with the temperature – with the "RATIO" wireless thermometer from TFA.
A separate wireless transmitter determines the outdoor temperature at the location; an internal sensor measures the indoor temperature.
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 a reliable and important information for your home, garden, leisure and work.
In addition, the device has a memory for highest and lowest values and a display for the time.
Two more transmitters for temperature can be connected, thus allowing the monitoring of other rooms, e.g. in the nursery, bedroom, cellar or garage.
- Wireless transmission of outdoor temperature via transmitter (max. 3)
- Indication of indoor temperature
- Max.-min. function
