Measuring humidity in your humidor is dependent on the accuracy of your hygrometer. Calibrate a new digital hygrometer or humidity sensor before you use it, then re-calibrate it every six (6) months to get accurate readings to ensure the safety of your cigars. With Boveda, calibration is one-step easy. (Hygrometer not included.)

Information

DETAILS:

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:

  • Replace the messy, inaccurate bottle cap salt test
  • 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 (6) months

HOW TO USE:

  1. Place your hygrometer/sensor inside the kit and completely reclose the zipper.
  2. Allow the kit to sit for a minimum of 24 hours at a room temperature between 65 and 75°F.
  3. Check the reading of the hygrometer/sensor:
    - If the reading is 75% RH, this calibration is complete.
    - If the reading is higher or lower than 75% RH: Note the difference as the margin of error for future readings. Or manually adjust your settings to 75% RH and repeat the above three (3) steps.
  • Reclose the bag with the Boveda packet inside to reuse the kit within three (3) months. 
  • Recalibrate your hygrometer every six (6) months to keep it performing effectively.
  • DO NOT mix different RH (Relative Humidity) levels within the same humidor.
  • DO NOT use Boveda in the same humidor with other humidification products because they'll counteract each other, and reduce the efficiency of the Boveda.

PACKAGING:

The B75 Boveda (75% RH) is not individually wrapped inside the resealable high-barrier heavy-duty plastic bag, which has a zip closure. 

SPECIFICATIONS:

Please measure your hygrometer to make sure it will fit in the kit. Non-gusseted bag. 

5.5"/13.97 cm x 7"/17.78 cm

LIFESPAN:

  • Opened: Three (3) months
  • Unopened Kit: Up to two (2) years

ACCURACY:

Boveda maintains inside relative humidity (RH) of +/-2% when using the recommended number of packets. Factors that adversely affect the expected results include a drafty humidor and/or extreme dry ambient conditions.

INGREDIENTS:

Food-grade salt, purified water, and a food-grade thickening agent.

    I calibrated 4 of my hygrometers and I am pleased to announce that they were all at 75.

    Works like a charm

    Another great product from a great company. Not all hygrometers are alike so following instructions is important for best results.
