Duo Digital Hygrometer Thermometer

This portable thermometer measures the humidity and temperature in the room. The indoor climate level is represented by a smiley icon next to the indoor temperature and humidity values. The temperature is indicated in °C or in Fahrenheit, according to your choice. On the back of the unit is a 3-position switch to select for °C, Fahrenheit or to. Switch off. Room temperature and humidity determine the drying time of the eyelash glue. The higher the humidity, the faster the eyelash glue usually dries. Here it depends on the properties of the adhesive. We recommend a temperature between 18 and 23° and an average humidity between 40 and 70%.
