Hygrometer Calibration Kit (75% RH)

Easy to understand and worked perfectly

I am so happy to have calibrated relative humidity measurements finally-- it looks like all of my old ones were way off. Either way, this kit was very easy to understand and the equipment was simple to use. Thank you Boveda!

Hygrometer Calibration

Works great! One cannot rely on even a high end hygrometer to be accurate. This is an easy, foolproof way to achieve accuracy.

I’m Calibrated

I was having issues with my humidor/hygrometer and purchased the calibration kit which did the job just right. Turns out my hygrometer was working just fine. I also purchased the tune up kit for my older humidor.
