PR293A temperature measuring instrument genaral descripion


The PR293 five-channel pyrometer is a portable electric measuring instrument for the temperature measurement industry. It has a 0.005-level accuracy and comparable display resolution to a seven-and-a-half-digit digital multimeter, which is enough to replace the traditional high-end digital multimeter.The rich temperature measurement function makes the temperature calibration and temperature measurement process easier.


Performance characteristics:

1. It meets the requirements of the AA grade platinum resistance for electrical measuring instruments, and the 0.005 level measurement accuracy can be achieved in the environment of 5 °C ~ 40 °C.
2. The independent temperature difference measurement mode makes it easy to calibrate various types of measuring thermostats and calibration furnaces.

3. It has five rear-mounted electrical measuring channels, supports a wide range of standard/working/industrial temperature sensors, and can trace the measurement results using certificate values/correction values. Ø In the inspection mode, data can be recorded on the inspection data through the U disk.

4. In addition to displaying the temperature profile, the statistics function performs maximum/minimum/average calculations on the data and performs a variety of temperature volatility calculations.
5. Built-in high-capacity lithium battery, low power design, can work continuously for more than 10 hours.

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.
