75% One-Step Calibration Kit, Verify Hygrometer Accuracy

Key features

• INACCURATE HYGROMETER READINGS PUT PREMIUM CIGARS AT RISK. Precisely calibrate digital and analog hygrometer and humidity sensors, so they give accurate relative humidity (RH) readings of what’s going on inside a humidor
• PATENTED SALTWATER-BASED BOVEDA is the ultimate salt test! Do-it-yourself calibration methods, like bottle cap salt tests are imprecise and inaccurate
• EASY, MESS-FREE CALIBRATION—Simply place a hygrometer or humidity sensor in the airtight high-density bag with the enclosed Boveda humidity pack. Zip closed and check back in a day
• GET PRECISE RH READING IN 24 HOURS—If a hygrometer doesn’t read 75% RH, adjust by the number of points it’s off, then re-test. For added accuracy, do a 2-point calibration with a 32% RH Boveda One-Step Calibration Kit (sold separately)
• REUSABLE FOR MULTIPLE HYGROMETERS/SENSORS—Good for 3 months after opening (2 years if unopened in original packaging). Re-calibrate a hygrometer or humidity sensor every 6 months to keep it performing effectively

Even if your hygrometer says it doesn’t need to be calibrated, it does—every 6 months. Find out if your hygrometer is giving accurate readings with the Boveda One-Step Calibration Kit, an easy-to-use, professional-level salt test. An uncalibrated hygrometer is like using no hygrometer. You’ll never get an accurate relative humidity (RH) reading from a hygrometer or humidity sensor until it’s precisely calibrated. A well-calibrated hygrometer gauges if your premium cigars are stored at proper RH. Chemists and lab professionals determine the accuracy of a hygrometer with a “salt” test. Unlike the bottle cap salt test, the Boveda One-Step Calibration Kit is precise, mess-free and ready-to-use. Just slip a hygrometer in the airtight, high-density bag preloaded with Boveda. The patented saltwater-based pack uses natural salts and pure water to achieve 75% RH inside the bag. After 24 hours, check the hygrometer’s reading. If it doesn’t read 75% RH, your hygrometer is off. Simply adjust it, zip it back in the bag with the Boveda and verify the reading the next day. For added accuracy, perform a 2-point calibration with the 32% RH Boveda One-Step Calibration Kit (sold separately) to check
