Want to buy a home temperature hygrometer, electronic and dial which is more accurate?RT what should be noted when choosing how to know whether the instrument is accurate?
Household level of temperature and humidity meter accuracy at + 1 C and + 5%RH, while the dial is basically a hair hygrometer, the accuracy is poor, the humidity is in the + 7%RH, the reading is obviously no electronic visualWhen you choose to look at the price, look at Taobao sales and evaluation,
The electron is more accurate than the dial, the electronic home temperature hygrometer uses the thermal resistance and the humidity sensitive resistor
Because there can be no calibration identification of professional equipment at home, so with a mercury thermometer compare to try it, more accurate measurement of humidity is the dry bulb temperature and humidity meter, but there are few places to sell, the price is expensive, usually the temperature relatively good accuracy, of course, temperature and humidity meter technology is now mature, basically do not have to worry about this problem
