Do you have to calibrate a digital hygrometer?
Digital hygrometers are more precise than analog hygrometers but still most are accurate + or – 5 points. They are calibrated in the factory. We recommend that you check the calibration of your digital hygrometer using the salt method so that you know exactly the margin of error of your instrument.
How do you calibrate a digital hygrometer on Boveda?

How do I know if my hydrometer is accurate?
So, to check if your hydrometer accurately measures the specific gravity of water, simply float it in pure water (distilled or reverse osmosis water) at the correct temperature. Spin the hydrometer to dislodge any bubbles that may be clinging to it and bring the test jar up to eye level.
How do you know if a hygrometer is accurate?
How to Test a Hygrometer
- Gather supplies. To test your hygrometer using salt, you just need a few household supplies.
- Fill the cap with salt and add enough water to make a thick slurry.
- Put the cap and the hygrometer inside the baggie.
- Wait 6 hours.

How many times can I use the Boveda calibration kit?
Answer: Yes, these kits can be used multiple times as long as the Boveda pack is soft and you keep the seal closed tight during and in between calibrating hygrometers.
How can I make my hydrometer more accurate?
To do this, take a sample of distilled water at the temperature of the hydrometer’s calibration. If the hydrometer reading is 1.000, your instrument is correctly calibrated. If it is too high, you can use a file to shave off some of the glass from the bottom of the hydrometer until it hits 1.000.
