how do you measure your Humidity accurately?

That’s a good question, one I looked at a while. I bought a flock of those little humidity/temperature instruments and wanted to check.

You can do a simple one point calibration involving a salt paste.

The Salt Test @BarrieButsers suggested doing a salt test with the new hygrometers to check their accuracy, hey, why not? Setup Basically a tablespoon and a teaspoon (15ml) of salt in a container plus a teaspoon (5ml) of water (any will do). Mix into a paste and place in a sealed container with the hygrometer and it should level out at 75%. My ambient RH is about 32% I went with a zip-lock sandwich bag. Two days later they have settled out at 63%. [DSCN3008] Thinking about it, I wondere…

Some of the hygrometers they use for cigar humidors can be calibrated and that’s how they do it.
