PR320A Thermocouple Calibration Furnace is a horizontal, open-ended tube furnace with a temperature range of 300 °C to 1200 °C. the temperature setting will be ultimately controlled type probe "N" by Czaki from Raszyn, the probe measures the temperature inside the furnace and working in the loop temperature controller, diameter of the heating tube is 40 mm. length 600 mm. The PR320  is the most accurate, reliable, and flexible furnace in its class, meeting the demanding requirements of high-temperature thermocouple calibration.  

Tube furnace configuration (without isothermal block): Base-metal thermocouples are often sheathed in formable materials such as braided fiberglass or PTFE. During calibration, they are bundled around a reference thermometer, held together with fiberglass cord or tape, and inserted into a tube furnace.
