Boveda One Step Hygrometer Mess Free Calibration Kit Preloaded 75 RH 2Way Humidity Control Hygrometer Accuracy Precise Test for Digital and Analog Hygrometers and Humidity Sensors 1 Count

PRECISE HYGROMETER READINGS: Our on-step hygrometer calibration kt makes sure your hygrometer is giving accurate readings. Precisely calibrate digital and analog hygrometer and humidity sensors, so they give accurate relative humidity (RH) readings of what’s going on inside a wooden storage box. Even if your hygrometer says it doesn’t need to be calibrated, it does—every 6 months. A perfectly calibrated hygrometer will read 75% or 32% RH., EASY & MESS-FREE CALIBRATION: Simply place a hygrometer or humidity sensor in the airtight bag with the enclosed Boveda humidity pack. Zip closed and check back 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 calibration Kit. If your hygrometer reads above or below that number, adjust the calibration by the number of percentage points it is off from 75% or 32% RH, REUSABLE: 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. The One-Step Calibration Kit is a simple and surefire method to accurately calibrate any digital or analog hygrometer or humidity sensor., ULTIMATE SALT TEST: Inaccurate Hygrometer readings put premium sticks 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. Do-it-yourself calibration methods, like bottle cap salt tests, are imprecise and inaccurate. Good for three months after opening!, ABOUT US: Boveda devoted the past 23 years to the science of two-way humidity control, we know you will benefit from our commitment to precision. Becoming the global leader in any category does not happen overnight, but Boveda did this and continues to do so since 1997. Today, that persistence looks like millions of two-way humidity control packets getting shipped out each year to protect your finest rolls.
