PR320 Thermocouple Calibration Furnace is a horizontal, open-ended tube furnace temperature range of 300 °C to 1300 °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.
