Boveda One-Step 75% Hygrometer Calibration Kit for Cannabis and Hemp

Are you sure your cannabis hygrometer is telling the truth? Is your weed really between 58-62% RH? Hygrometers are finicky and must be calibrated to provide accurate readings.

If not, the RH could climb above 65% RH or plummet below 55% RH and you'd never know. The wrong RH puts cannabis at risk for moldy weed, overly-dry weed, terpene loss and trichome damage. Even hours outside the ideal RH range matter.

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

Calibrate a hygrometer more often if you struggle with:

• Low or high RH readings
• Blowing through Boveda in less than two months
• Maintaining steady RH in a cannabis container
