Use a standard thermocouple, check the product before use and verification numbering standard even numbered certificate are the same. 2, even when using the standard from the glass outer jacket pipe out into the quartz tube outer jacket can be measured. After use, re placed outside the glass protective tube for storage. 3, the use of second-class standard thermocouple industrial thermocouple WRPB-2 test, a standard reference junction thermocouple should be even and measured in at 0 ℃. Specific methods and procedures approved by Quality and Technical Supervision issued a "standard platinum and rhodium 10 - platinum thermocouple test procedures" (JJG75-95) performed. 4, using a standard even for precision temperature measurements, the temperature t is determined by the following formula :( In this equation omitted) Second standard thermocouple EMF stability by copper point change (the difference between the two thermoelectric power) decided, R platinum rhodium thermocouple manufacturer, thermocouple newly created second-class standard of no more than 5uV, the amount of change in the use of copper in the second standard thermocouple thermoelectric power point does not exceed the standard thermocouple 10uV often used, R-type platinum-rhodium thermocouple In order to ensure accurate and reliable measure, should carry out the necessary oversight of the check based on usage. Second supervisory standard thermocouple calibration standards are first-class or second-class standard thermocouple thermocouple infrequently used as a standard device, its qualified or not from the point on the measured copper and thermoelectric power measurement verification certificate given thermoelectric potential difference between the decision (the difference is not more than 7uV).
