Ok, so I filled a soda pop lid with salt and got it a little wet, so I placed a papertowel on it to soak up the excess. I placed 3 hygrometers in it. One is a digital xikar hygrometer for humidors that when you calibrate it you hit the button and it sets that humidity level at 75% so you don't have to do the math. An accurite indoor/outdoor digital and cheapo reptile tank hygrometer. All of them say 60, 61, and 60. Soooo...it should be 75% its been 6 hours but since they all read the same. Should I assume they are all already accurate or that they are all about 15% off? If they differed in humidity I'd assume they all need to be calibrated. But they are all almost identical! Do I trust them and assume I did it wrong? *sigh
