有些计量检定人员利用数字仪表反应速度快、操作简便,对使用环境要求不高的优点,在检定工业用热电偶时,把数字式温度计当作检测设备,替代了直流电位差计,取得了一些成功经验。但是用数字式温度计测得的数值与检定热电偶时测得的数值有很大的差别。检定热电偶是温度量值的传递,
Some metrological verification personnel use digital instrumentation reaction speed, ease of operation, the use of the environment less demanding advantages in the verification of industrial thermocouple, the digital thermometer as a testing equipment, instead of the DC potentiometer, made some success experience. However, the values measured with a digital thermometer differ greatly from those measured with a thermocouple. Test thermocouple is the transfer of the temperature value,
