PR321 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 PR321 is the most accurate, reliable, and flexible furnace in its class, meeting the demanding requirements of high-temperature thermocouple calibration.
1. Application range：Calibrate S、R short thermocouple、short cheap metal thermocouple
2. Hearth size：φ40mm X 300mm
3. Temparature range：300-1200℃
4. Temperature field center：Deviate from the geometric center ≤10mm
5. Temperature field width：the temperature difference in 40mm ≤1℃
1.Wide temperature range spanning most high-temperature applications
2.Flexible configuration for calibrating a wide range of thermocouple types
3.Best-in-class temperature stability and uniformity for calibration accuracy
4.Automated setpoint control for improved lab productivity
5.Deep immersion depth to support most thermocouple calibrations
6.Calibrate most types of thermocouples up to 1200°C (2192°F).
It is used for comparison calibration of noble and base-metal thermocouples by secondary high-temperature labs and instrument shops in industries such as aerospace, automotive, energy, metals, and plastics.
