Digital Hygrometer Thermometer and Humidity

Room temperature and, above all, humidity directly affect how eyelash extension glue cures. This mini digital thermometer and hygrometer shows both readings at a glance, so you know the conditions you are working in every day and can adapt your adhesive or your room.

Features

• 2-in-1: temperature and relative humidity (%) on one LCD screen.
• Compact round design: about 45 mm in diameter and 15.5 mm deep, according to the photos.
• Button on the back to switch between °C and °F.
• Runs on a button cell battery housed in a rear compartment (see photos).
• Colours: white or black.

How to use

• Place it close to your working area, at the height of the treatment bed.
• Keep it away from direct sunlight and from heat or air sources, which distort the reading.
• Check the readings before each appointment and compare them with the range recommended by your glue manufacturer.
