Boveda One-Step 75% Hygrometer Calibration Kit

Inaccurate hygrometer readings put premium cigars at risk. Your cigars will smoke perfectly when you store them in a steady environment between 60 and 72% relative humidity (RH). So what’s the RH in your humidor?

Use this 75% RH Calibration Kit to:
Get an accurate RH reading in just 24 hours
Calibrate a new humidity sensor, digital hygrometer or analog hygrometer—even if it claims to be pre-calibrated, it will be inaccurate
Re-calibrate each hygrometer or sensor every six months
Replace the messy, inaccurate bottle cap salt test
You may need to calibrate your hygrometer if you struggle with:
Low RH readings
Blowing through Boveda in less than two months
Maintaining a wood humidor
