Wester Caliber III Hygro

Can these be calibrated? I got two of them used with a vino purchase and do not have the instructions.

They are not adjustable. You just have to add or subtract rh% when you salt test them. Mine are all within 2% either way.

Thanks, NCRadioMan. Mine are both sitting in a boveda calibration bag and reading 76%. Nice.

:tpd: I have been using mine for over 2 years and it is within 1%.

They can't be calibrated, but after salt test shouldn't be off more then 2%. I've got 5 of them and they are all within 1% or right on. Battery is easy to change as well. :tu

Mine are doing well so far. Thank you all for the advice!

In the FWIW category... The instructions tell you NOT to salt test, but I did anyway. Both of mine are now marked one at -1, the other at +2. Also FWIW, I prefer them by far to the adjustable ones which gave me fits trying to set...
