you can calibrate them at home its ez to do, its the digital ones that are junk most cases... if they cant be adjusted/calibrated then not worth a damn. You can take a 3.00 hygrometer and calibrate it as close to any certified 200.00 hygrometer in 1 day. Problem is ppl just toss them and dont realize how easy it is. The companies should put calibration instructions with the dial versions.
Thermometers are usually pretty close to accurate its the humidity that varies for some reason.
