PR401 100 Degree to 600 Degree Industrial Temperature range dry block temperature calibrator

PR400 series portable dry block furnace is a portable temperature source which takes advantage of good heat dissipation and temperature uniformity of solid metal.

It adopts imported intelligent PID temperature control instrument with small size, light weight, fast speed and other features.

It keeps pace with the advanced technology of foreign countries in technology, and in the domestic leading level in temperature stability,

horizontal temperature field,and vertical temperature field and so on.

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. PANRAN products are widely used in military-industrial complex system ( including aviation, aerospace, weapons, nuclear energy, ship ), measurement and calibration institutions, rolling stock, machinery, metallurgy, electric power, petroleum, chemical industry, instruments and meters industry etc. 



Products' quality is the basis of surviving, and satisfying customers' requirements is our mission. Panran is young but very energetic, and our all staff warmly welcome you and your company to come to us for an co-operation in near future. Panran making is more accuracy! Thanks very much!
