1. Boveda


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

Boveda #ad - Ultimate salt test: inaccurate hygrometer readings put premium sticks at risk. Precise hygrometer readings: our on-step hygrometer calibration kt makes sure your hygrometer is giving accurate readings. For added accuracy, do a 2-point calibration with a 32% RH Boveda calibration Kit.

Even if your hygrometer says it doesn’t need to be calibrated, it does—every 6 months. 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. Reusable: good for 3 months after opening 2 years if unopened in original packaging. If your hygrometer reads above or below that number, adjust by the number of points it’s off, adjust the calibration by the number of percentage points it is off from 75% or 32% RH.

Do-it-yourself calibration methods, like bottle cap salt tests, are imprecise and inaccurate. Good for three months after opening! . If a hygrometer doesn’t read 75% RH, then re-test. Re-calibrate a hygrometer or humidity sensor every 6 months to keep it performing effectively. A perfectly calibrated hygrometer will read 75% or 32% RH. About us: boveda devoted the past 23 years to the science of two-way humidity control, but Boveda did this and continues to do so since 1997.
