Digital Humidity Temperature
Are electronic thermometer/hydrometers really more accurate?
I threw out my Oregon Scientific weather kit because whenever i tested it by placing the main thing next to the wireless sensor, there was always a difference in reading by up to two or three degrees in temperature and by 10-15 percent on the humidity.
I was wondering if that was normal because im thinking about picking up another digital one but maybe this time i'll go for something cheaper.
No, both alcohol and digital thermometers have to be calibrated and how well it is done tells how accurate it will be. The same is valid for a hygrometer and, for the matter, a barometer. Usually, the more expensive the instrument, the more accurate it is because the calibration is better done. For example, the top range of a barometer is simply the aviation altimeter that must go through quality assurance that satisfies the aviation authorities and that's not easy, ask me, I am a pilot and aircraftft home builder!
This being said, you will always see a variation in a thermometer depending on where you place it. If it is on a dark wall of your home, don't expect to have the same temperature as the ground, after a cloudless night when much heat radiates back into space. You may see frost on the ground and yet, a few meters above it, on the wall of your home, it shows several degrees above freezing point.
Good luck with your purchase.
