Hygrometer Calibration Kit (75% RH)

Simple & Smart

Very easy to use, great quality zip pouch that could hold a good size Hygrometer, placed it in, I had 2 pouches, 1 for each and the results were amazing!

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!

Take the question of is my gadge correct

I used as directed. I marked correct %.
