Calibrating Your Hygrometer

To calibrate a hygrometer you will need:

  • 1/2 cup table salt
  • Approximately 1/4 cup water
  • Coffee cup
  • Large resealable freezer bag
  • Hygrometer
  1. Place 1/2 cup of salt in the coffee cup, and add the water. Stir for a bit to totally saturate the salt (the salt won't dissolve, it will be more like really wet sand).
  2. Place the cup of salt/water mix in a resealable plastic bag, along with the hygrometer, and seal the bag. Make sure none of the salt/water mix comes in direct contact with the hygrometer.
  3. Let this bag aside at room temperature for 8-12 hours, in a location where the temperature is fairly constant.
  4. After 8-12 hours, check the reading of the hygrometer. It is best to read it while still in the bag. The relative humidity in the sealed bag with the salt/water mix should be 75 percent (our test read about 72 percent).

For adjustable hygrometers, adjust to read 75 percent. You will have to do this very quickly, or remember how much you need to adjust the setting (e.g. our test read 72 percent rather than 75 percent, so I would need to adjust the dial up 3 percentage points). If yours is not adjustable , simply make a note of how "off" your hygrometer reads. If it reads below 75 percent, you will need to add the difference to your actual readings. If your hygrometer read above 75 percent on the calibration, you will need to subtract the difference from your actual reading.

Our test: After sitting in the bag, our hygrometer read 72 percent, when it should have read 75 percent, a difference of 3 percent. I now add 3 percent to the readings I take on the hygrometer (e.g. in a tank) to get the actual relative humidity.

Remember: Always give a hygrometer about 2 hours to stabilize before taking a reading, as changes in the relative humidity may take a while to register accurately on a hygrometer.
