Embodiment Construction
[0039] When carrying out mercury or alcohol thermometer verification, selected one group of verification temperature is generally the temperature value represented by the long scale line, for a certain selected verification temperature, the automatic verification method of the present invention is as follows: figure 1 shown, including the following steps:
[0040]Step 1: Place the verified standard thermometer and the verified thermometer in a constant temperature bath together, adjust the temperature of the constant temperature bath to the approximate verification temperature, and the approximate verification temperature is approximately equal to or equal to the selected verification temperature. temperature; here, since the computer figure 2 The shown temperature control unit 3 adjusts the temperature of the constant temperature tank, and the computer outputs the verification temperature, and compares it with the real-time temperature of the constant temperature tank fed ba...
