Window open or closed? Heating on or off? Finding the optimal indoor climate is often not that easy. A practical aid is the TWIN PLUS wireless thermo-hygrometer from TFA.

Internal sensors measure the indoor temperature and humidity. Monitoring the indoor climate ensures a pleasant living environment and also helps prevent mold formation.

The outdoor temperature and humidity are measured via a separate transmitter, providing important information for home, garden, leisure, and work. Daily high and low values are continuously displayed and automatically reset.

With the comfort icon, the values are evaluated directly, and a temperature and humidity alarm can be freely set. When temperatures are likely to drop below freezing, a frost symbol appears on the display.
