## Overview

The Boveda One-Step Hygrometer Calibration Kit offers a simple, maintenance-free method to calibrate any digital or analog hygrometer with a precise 75% relative humidity environment. Just place your device inside the airtight bag, wait 24 hours, and adjust your readings accordingly. Designed for repeated use over a year, this compact kit is trusted by professionals for reliable, lab-grade accuracy without the hassle of salt solutions or complex setups.

## Description

The Boveda One-Step Calibration Kit is a simple and surefire method to accurately calibrate any digital or analog hygrometer or humidity sensor. The One-Step Calibration Kit utilizes Boveda's 75.5% relative humidity standard, which is widely used and accepted by chemists and lab professionals to determine the accuracy of any hygrometer (also known as the \"salt test\"). Simply place your hygrometer inside the bag, close the zipper, and wait 24 hours. A perfectly-calibrated hygrometer will read 75% Rh. If your hygrometer reads above or below 75%, adjust the calibration by the number of percentage points it is off from 75%.

Review: Excellent - I'm in the process of designing a product that measures the temperature and humidity of beehives. There are plenty of temperature sensors on the market that are cheap and accurate, but humidity sensors are generally pretty expensive in comparison and, as I've discovered, wildly inaccurate. Having purchased a sensor that I had some confidence in, I needed to test it. I created my own testbed, with very accurate control of temperature, but I needed a way to accurately define a level of humidity. There are a plethora of YouTube vids on the subject demonstrating how this can be achieved using a home-made salt solution in a bottle cap, but even having purchased some lab-grade sodium chloride and distilled water my results were all over the place. It was while I was doing more research along these lines when I can across some adverts for Boveda products in relation to maintaining the humidity in humidors, a cupboard for cigars. Looking at the Boveda website I discovered that they produce larger product packs for cigars, but also produce smaller packs with high tolerance chemical solutions that can be used for hygrometer (an instrument used for measuring the amount of humidity and water vapour in the atmosphere) calibration and purchased a pack. The Boveda One-Step Hygrometer Calibration Kit allows a high degree of reliability, with a high degree of accuracy simply by placing the hygrometer, or in my case the sensor, in a small airtight container. The kit comes complete with an air-tight plastic bag and the Boveda humidity pack. To use it, you just put the device to be tested in the bad and let the humidity in the bag settle for 12 hours or so, it's as simple as that. In my case, I placed the sensor in a small bag, sealed the bag around the wires from the sensor and placed the whole pack into my chiller. At a consistent 21.5 DegC (+/- 0.3 DegC), I let the sensor soak for a day and then analysed the results. Long story short then, the results where excellent. Incredibly stable humidity results, at exactly the level I was expecting, well within the tolerances stated by Bovida and the sensor I was calibrating during my experiments. I certainly won't be mucking about with salt solutions any more. My only regret is that I've spent a fair amount of money of lab-grade chemicals and that my better half is getting peeved with the 1Kg of salt that's taking up cupboard space. Still, I guess I can use it on my fish & chips?
Review: Perfect Calibration for Small Hygrometers - This is a must have for anyone wanting to check and adjust a small hygrometer. Very easy to use and gives reliable results. Even if your hygrometer is not adjustable you can at least see if it is in error and mentally compensate to get a true RH reading.

## Features

- Simply place your hygrometer inside the bag, close the zipper, and wait 24 hours. A perfectly-calibrated hygrometer will read 75% RH. If your hygrometer reads above or below 75%, adjust the calibration by the number of percentage points it is off from 75%.
- Completely maintenance free - no activation required. Easy to use.
- Lasts approximately one year, good for multiple calibrations. Shelf life before opening is a minimum of 2 years.
- Produces an environment of 75-percent humidity
- Exterior Bag Dimensions: 5.5" x 7"
- Interior Bag Dimensions: Approx 4" x 4.5"

I got this to measure the humidity for a cigar humidor. Easy to connect to Bluetooth. I calibrated the humidity and it was spot on with no adjustments needed.
