Wanted to check the calibration of the relative humidity sensors on two items, Anemometer HoldPeak 866B and Miniature Digital Hygrometer. So I did the salt slurry test on both and a potassium hydroxide test on the cheap sensor. The quality control on the little display is not amazing, see location in description below, was there a shortage of solder.
