## Overview

The Boveda One Step Hygrometer Calibration Kit delivers a patented, saltwater-based 75% RH environment inside a mess-free, airtight bag, enabling precise and effortless calibration of digital and analog hygrometers. Designed for professionals and enthusiasts, it ensures your humidity readings are accurate, reliable, and maintenance-free for up to one year, making it the essential tool for perfect humidity control.

## Description

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 the high and low RH readings of your hygrometer. Note: Do not mix different Boveda RH levels within the same humidor. And do not use Boveda in the same humidor with other humidification products because they will fight against each other and reduce the efficiency of Boveda.
