3KW Thermocouple Calibration Furnace
High Temperature Thermocouple Calibration Furnace
PANRAN TECHNOLOGY as a drafting unit of” JJF1184-2007 Testing Specification of Temperature Uniformity in the Thermocouple Calibration Furnaces”, PANRAN has long been committed to the research and production of thermocouple calibration furnace. Compared with KRJ series products, the PR320 series,as the latest generation calibration Furnace , has a wider temperature range and better long-term stability. Its core technology can ensure that the uniform temperature field width and other specifications exceed the relevant national verification regulations.

The PR322 series is equipped with a special power control cabinet:
1. Adopts patented multiple over-current protection, and is provided with power-on soft start, heating current limitation, freewheeling protection, automatic stop and other functions.
2. No manual voltage gear shift or meter adjustment is required for power-on and heating process.
3. Equipped with RS485 and RS232 dual-communication connections.
4. Configured with ZRJ series calibration system software, the functions of start/stop, real-time recording, parameter query setting, etc. can be achieved.
5. While protecting the safety of the equipment, the manual operation is greatly simplified.
