Modern design and clear high-resolution LCD display. Don't give mold a chance to grow. Recognize room humidity immediately and act quickly. Our digital thermo-hygrometers are suitable for indoor and outdoor use. Humidity is measured from 10% to 99% and displayed immediately. Temperatures from - 50 to +70 Free CR 2032 button cell battery included. an ideal indoor climate not only has a positive effect on our well-being, it is also beneficial for our health. The two key values that determine the indoor climate are temperature and relative humidity. For example, too little humidity not only causes burning eyes and chapped lips. It also leads to a dry nasal mucosa, which then no longer offers protection against inhaled pathogens. If the humidity is too high, however, there is a risk of mold growth. 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 that shows both the current temperature (C) and the humidity (%). With the symbolic form, you can quickly see whether the values are in the recommended range or whether there is a need for action. A practical and useful device. Thanks to the compact design, the thermo/hygrometer can be used almost anywhere. The thermo-hygrometer is operated with a CR 2032 button cell, which is included in the scope of delivery. Reduce your heating costs through unnecessary ventilation. Create the perfect room temperature and don't give mold a chance to grow by controlling the humidity in your rooms and regulating it with ventilation. Our recommendation is to have a thermo/hygrometer in every bathroom/bedroom/living room/workroom to create a perfect humidity level in your entire living and working area.
