Caliber 4R - Gold Digital Round Thermo-Hygrometer

Date Added: Monday 27 July, 2015 by Staff

Similar to what I mentioned about the Caliber IV hygrometer, the 4R works in the same way delivering accuracy and precision. Although what's noticeably different is the style as it retains the traditional looks of an analogue hygrometer, but with the benefits of the updated digital features. If you like the Digital hygrometer but like the retro feel, pick one of these up!
