Review: It works. - This is a wonderful little device. I have had mine for many years and it gives reliable readings of time, temperature and best of all, relative humidity - one of the few devices in this price range that does. Review: All the features I need! - I own another hygrometer by the same company and it worked great! I'm a lash extension technician, monitor the humidity level and temperature in my work space is extremely important for the adhesive we use to work smoothly and properly. Only problem is when getting busy I always have hard times keep track of time. I wanted a hygrometer that not only monitors the humidity level and temperature, but also display time so I'm able to keep everything in control with a glance. Such a device was surprisingly hard to find. I was so happy I found this one, and it's even better it's from a brand that I already know and trust:) ## Features - SIMULTANEOUS TRIPLE DISPLAY: View time, temperature, and humidity all at once on a crisp LCD screen.
