Description
Checking with an external standard thermometer
Weika standard thermometers are particularly suitable for use in industrial laboratories, making it easy to compare and verify in calibration tanks, tube furnaces and dry well calibrators.
It is recommended to use an external reference thermometer, especially when verifying shorter temperature sensors. This can greatly reduce the error caused by the axial and radial distribution of the temperature in the temperature adjustment unit.
CTR series of precision measuring instruments, especially the CTR3000 multi-function precision thermometer, is more suitable for use as a temperature measuring instrument.
When verifying, the device under test and the standard thermometer are at the same temperature in the temperature adjustment unit.
Once the temperature is stable, the system will read the temperature of the device under test or measure the output signal of the device under test (resistance, thermal voltage and standard signal, etc.), then measure the reading and standard thermometer Values ​​are compared. This comparison method not only considers the display of the temperature adjustment unit, but also considers many other factors, thus greatly reducing the measurement uncertainty.
