How to calibrate your Case Elegance hygrometer - Digital and Analog

Calibrate Your Case Elegance Hygrometer - Digital & Analog instructions

A note about calibration - in our digital humidor models (Renzo glass top, carbon fiber, and cherry, but not the octodor) purchased prior to mid-january 2020 - the front gauge will read from 5 - 8% lower than the inside where your cigars sit. This is due to where the sensor is placed, as well as holes in the hygrometer allowing air to pass through easily to the sensor. To fix this - we have additional hygrometers available free of charge that is adjusted +4% and with better interior silicone sealing to prevent as much passthrough.

Longer term we are working on placing the sensor in the rear of the humidor as this is the most accurate place we've found to measure humidity in the box. When we release this new hygrometer it will also be available free of charge to any effected customers.

Most of the time customers who complain about "calibration" are complaining about this difference - so our recommended solution is to request a new hygrometer from us at for free, then take the old hygrometer and place inside the humidor where your cigars sit - to get the most complete picture of your cigars humidity.

  1. Place a teaspoon of salt in a bottle cap or small cup and dampen it with a few drops of water (without dissolving it).

  2. Carefully place the wet salt and the hygrometer inside a see-through container and close tightly. You can use a zip lock bag provided it seals well and you leave some air inside as well.

  3. Let it sit for at least 6 hours and note the reading on the hygrometer without opening the container. The hygrometer should read 75%. The difference is how much your hygrometer is off. For example, if your hygrometer reads 70% during the salt method test this means that to obtain the real humidity level you should add 5 points.

  4. If you have an analog hygrometer, you can correct the reading. Simply make a mark on the reading immediately after pulling from the bag with the salt solution. For instance, if the hygrometer reads 60%, then take a sharpie and mark the 60% line. This is now 75% and when you read your hygrometer and it's reading 60%, then you will know it's actually at 75%.

    IMPORTANT: YOU MUST FOLLOW THE ABOVE INSTRUCTIONS (put salt and hygrometer inside ziploc) BEFORE HOLDING THE BUTTON ON THE BACK - FAILURE TO DO SO WILL UNCALIBRATE A LIKELY CALIBRATED HYGROMETER. If you have a digital hygrometer (built into the front), you can hold the button the back of the unit for 5 seconds to calibrate it to 75%.

    If you have a round digital hygrometer, you can turn the knob on the front - 1 turn equals 1%.

  5. Your hygrometer is now ready to be placed back inside your humidor.
