< p > 1 error value < / p > < p > according to the actual situation of temperature and humidity meter the production and use, to determine the maximum allowable temperature error: plus or minus 2 ℃.
Humidity as: of error of plus or minus 5% RH (
40% rh ~ 70% rh, 20℃)
、± 7%RH(
Above or below 40% RH to 70% RH, 20 ℃)
。
This is considering the following reasons: < / p > < p > a, the current domestic manufacturers of mechanical factory index of temperature and humidity meter is generally used in industry as: + / - 5% RH, plus or minus 1 ℃ ~ + 2 ℃.
< / p > < p > b, industrial environment humidity range, generally between 40% RH to 70% RH, temperature generally at about 18 ℃ to 25 ℃, the range of temperature and humidity requirements is higher.
< / p > < p > c, hair and other mechanical hygrometer are low-grade equipment, generally does not apply to low humidity and high temperature and high humidity and other special occasions.
< / p > < p > d, relative humidity of the parameters on the temperature dependence, so the technical index of the relative humidity should be presented under a certain temperature.
< / p > < p > 2 wet/temperature hysteresis error return difference < / p > < p > temperature return difference as: 0.
