一、供电电源对干电池供电的数字湿度计,应注意电池电量,若提示电量不足,应更换电池后再检定/校准,避免电量不足对测量结果产生影响。二、标准器及配套设备的选择检定/校准这类湿度计可选择的标准器有:精密露点仪和标准通风干湿表。由于通风干湿表的湿度除与温度、大气压力有关外,还受风速、水质及纱布等因素的影响,因此目前绝大多数实验室用精密露点仪作标准器。配套设备有温湿度检定箱和湿度发生器。
First, the power supply Dry battery-powered digital hygrometer, should pay attention to the battery power, if the battery power is not enough, should be replaced after the battery test / calibration, to avoid the lack of power have an impact on the measurement results. Second, the standard equipment and equipment selection test / calibration of these hygrometers can choose the standard equipment: precision dewpoint meter and standard ventilation table. As the ventilation humidity table in addition to humidity and temperature, atmospheric pressure, but also by the wind speed, water quality and gauze and other factors, so most of the current laboratory precision dew point instrument as a standard device. Supporting equipment temperature and humidity test box and humidity generator.
