Humidity meters are a useful device to ensure that your home or workplace is kept at a reasonable humidity to avoid problems caused by dampness or extreme dry conditions.
Here's a look at how you can check their accuracy and how they work.

Awesome video! Thank you so much.
i have the same unit it used to read 75 and then the battery started to run down I changes it and it now reads 78 with 2 new batteries, I don't know how to change it, I suppose i assume it's +3 as my Bovida packs are 75
Failed condom……
Great job. Thorough and even authoritative
Thanks for showing us how to test the accuracy i was a bit worried about that and now i have something to help me out!
I know that this is an old video, but still relavent. I recently bought five of these on ebay. They were cheap, but I expected them to be fairly accurate. However two had an error of -7% and one of -8%. As they work on resistance, do you think that they could be recalibrated by soldering a resistor across them? I have quite a few around so I wouldn't cost me anything. But before I start it would be nice to know if someone has done this and what values to add. This would only work if the voltage needed to be lowered. I don't know of any way to increase the voltage if that is required. I need to raise the displayed value by 7%. (I think that the resistance will decreace with an increase in humidity, so adding a high value resistor in parallel has a chance of working and raising the displayed value.)
At some point the work surface got more board marks. 6 years ago it was pristine!
I have these things all through the house,all acceptably accurate. Any discrepancy I just take the average. Very useful little devices.
That accent, awesome!
what humidity level is bad for storing electronics? not powered on, but would like to know if I pull the plugs on sth like speakers or a tv and only have them powered on for a short time over a day is bad if its sth like 70-80%? I plan to store stuff in the attic and got it boarded up with osb but there will always be parts that leak to the outside.
I learned so much in 7 mins thank my good sir..
Are these little units resettable? After you bring them to 75%, is there a reset button than allows you to make it read correctly? I could not tell if there was a reset button when you took it apart. Enjoyed your video. Thanks
Boveda brand sells salt packs with different humidity settings including a 75% and 33% humidity for calibrating humidity meters…
Man, that is amazing. Humidity cal for cheap meters. Thank you so much for this!
A great fan of your videos. Please make a video about the humidity sensors that comes with common xh-m452 temperature humidity controller used in egg incubators.
Currently most use this "asair am2120" and it doesn't works for more then 2 weeks.
