Re: Yet another Shilala question.....
Micheal's site "Says" that the hygrometers should be calibrated out of the box, but it also says that shipping and such can mess up the readings on a hygrometer.
Sooo.... You should calibrate your hygrometer. I ordered one of the calibration packs with my hygrometer, it was only a dollar. I would trust the pack over the salt test anyday.
