 *PANRAN Calibrator PR320C Armoured Thermocouple Calibrator oven with Nickel-Chromium-Silicon temperature controlling module

Armoured Thermocouple Calibrator  furnace General description

PR320 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.

Panran Measurement and Control Science and Technology Co.Ltd(Changsha Panran Commerce and Trade Co., Ltd is the foreign trade office) is the member of Chinese national temperature measurement technology committee. Panran is the most professional manufacturer in temperature and pressure measurement tools and instruments' calibration field in China. We own temperature and pressure calibration instruments production line, and research developing laboratories, and experienced soft-wares writers, besides, we also authorized to international manufacturing.



We are participated in many national measurement technical specification drafting, such as "JJF 1098-2003 Calibration Specification for Auto-Measure System of Thermocouples and Resistance Thermometers", "JJF ll71-2007 Calibration Specification for Temperature Itinerant Detecting Instrument" and "JJF ll84-2007 Testing Specification of Temperature Uniformity in Thermocouple Calibration Furnaces" and so on. We have established some big temperature and pressure research laboratories to improve the temperature and pressure accurancy in many cities of China. Panran passed ISO9001:2015 Quality Management Certificate. We are High-Tech Enterprice certificated and get the sponsored funds from Chinese official office. Some products passed CE and SGS certificates and enter the international market. We win high reputation in China and many other countries, such as Poland, Brazil, Iran, Egypt, Vietnam, Russia,Sri Lanka, Colombia, Malaysia, Indonesia, Saudi Arabia, Pakistan, Philippines



Panran main products are temperature calibration instruments, presure calibration instruments and automatic calibration system sofewares. Our "ZRJ intelligent thermotechnic instrument calibration system", "KRJ wide temperature field thermocouple calibration furnace" and "PR600 series heat pipe thermostatic bath" etc. are independently developed by us, and they are keeping first lever technical position in China.
