How to Calibrate a Hygrometer

[dustbone]

After seeing a lot of confusion on how to perform the salt test, I made a video titled How to Calibrate a Hygrometer:

Hope you find it helpful. I literally created it because other videos on the topic seemed to miss some important points.

Thanks, that's the way I do mine too, is with salt.
Alot of folks use Bovedas as well.

Very well done !! Thank you. But I missed the part where you change the reading ?

[smoorman]

There is no changing the reading you just have to compensate for it per the example in the video. For example if yours says 71rh instead of 75 you would add 4 to your reading.

Thank you, Smoorman.
