Description We have the solution to your problem, an ideal indoor climate not only has a positive effect on our well-being, it is also beneficial for our health. The two decisive values that determine the indoor climate are temperature and relative humidity. For example, too low humidity does not only cause burning eyes and brittle lips. It also leads to a dry nasal mucosa, which then no longer offers protection against inhaled pathogens. However, if the humidity is too high, there is a risk of mould formation. You can also prevent this thanks to the indicator. This is a combination of thermometer and hygrometer for indoor and outdoor use. The Mini Thermo/Hygrometers have a large, easy-to-read LCD display, which displays both the current temperature (C) and the humidity (%) . With the symbolic form, you can quickly recognize whether the values are in the recommended range, or if there is a need for action. A practical and useful device. Thanks to the compact design, the thermo/hygrometers can be used almost anywhere. The thermo-hygrometers are operated with a CR 2032 button cell , which is included in the scope of delivery.
