Reach 1600 Degree C High Temperature Furnace Thermocouple
Calibration
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.
