## Overview

The Boveda One-Step Calibration Kit offers a patented, saltwater-based humidity pack that creates a stable 75% RH environment inside an airtight bag, enabling precise calibration of digital and analog hygrometers within 24 hours. Designed for mess-free, reusable use up to 3 months, it ensures your humidity sensors deliver accurate readings critical for maintaining premium cigar quality.

## 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.

Review: Works Well and Accurate - I use humidity sensors in terrariums. With high humidity sensors will raise the humidity as much as 10% in only a few months. For me accuracy is very important. The Boveda calibration kit worked very well for me bringing the calibration within 1% of the 75% target. I especially like the size as I can calibrate more than one sensor at a time. Depending on the size of your sensors they will fit 2 or more. This best part is the accuracy and ease of use.
Review: The Best Possible Way to Calibrate a Hygrometer. - Prior to becoming aware of Boveda products, I attempted to calibrate my three digital hygrometers (one Diamond Crown and two Xikars) using the 24 hour "salt test." I repeated this test on four different occasions and each hygrometer had a different reading after each one. I used the same sized ziplock bag and tried to create the same salt>water ratio each time but got different results despite this. This experience indicates to me that when performing the salt test at home with a ziplock bag, the humidity inside the bag varies depending on the ratio of salt to water in your particular mixture, which creates a different reading for each test and thus, no usable baseline for calibration. This is just a hypothesis based on my experience. After my lack of success with the salt test method I ran across the Boveda One-Step Hygrometer Calibration Kit and promptly ordered it. With this item there is no guesswork or struggle involved. Boveda has already done the work for you in creating a packet, which emits EXACTLY 75.5% humidity. All you have to do is stick your hygrometers in the bag, wait 24 hours and you have a precise result, which tells you definitively how accurate your hygrometer is. I didn't feel comfortable leaving my precious (and expensive) cigars inside my new humidor without knowing the humidity level inside. This is a great product and is infinitely preferable to the salt test; highly recommended. Thanks Boveda.

## 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

### ⭐⭐⭐⭐⭐ Work beautifully and cheap as dirt!
*by D***X on September 9, 2012*

I have been looking for a way to calibrate my various humidity meters and controls without spending $50 on the little calibration bottles that I always see. I finally ran across these and they work perfectly! The bag contains a packet that diffuses moisture to a specific level (75.5%) so you just put your device in there, wait 24-36 hours and check your reading. The one thing to note is that the included bag is quite small, about 5.5" square, and really doesn't fit anything bu the smallest devices. I decided to use a 1 quart Ziplok freezer bag instead which is just a bit larger and will hold any of my devices- Control3 humidity controllers, Wind and Weather stand-alone and remote sensors, etc. The bag is still small enough that the packet won't take forever to diffuse moisture into it. I had steady readings of 75-76% (which makes sense for a 75.5% packet) after 24 hours. All in all for the price this product is miraculous. The packet even claims to last 3 months once it's open. Heck, for the money I'm happy it lasts a week!
