Abstract In the process of thermocouple calibration, there are some problems such as temperature control lag, long constant temperature time, electric leakage and furnace tube bending caused by using the traditional thermostatic block for calibration furnace. Therefore, a calibration furnace with multiple calorifiers which can meet the requirements of relevant specifications without the temperature uniformity of the thermostatic block has been developed to improve the calibration efficiency. Firstly, according to JJF 1184-2007 Testing Specifications for Temperature Uniformity in Thermocouple Calibration Furnaces, the temperature uniformity of the traditional calibration furnace with single calorifier equipped with the thermostatic block and the calibration furnace with multiple calorifiers without the thermostatic block are tested respectively. Secondly, the two kinds of temperature uniformity are compared and verified by thermocouple indication error test. The results show that in the temperature range of 400～1000℃, the calibration furnace with multiple calorifiers without the thermostatic block is superior to the traditional calibration furnace with single calorifier equipped with the thermostatic block in the axial temperature uniformity, radial temperature uniformity, thermocouple indication error and other tests.

Key words： metrology thermocouple calibration furnace thermostatic block multiple calorifier temperature uniformity
