The PR322 series high-temperature thermocouple calibration furnaces operate in the temperature range of 800℃～1600℃. They are mainly used as temperature sources for calibrating secondary standard Type B thermocouples and various working Type B thermocouples. Their temperature field indicators meet the requirements of the current JJF 1184-2024 Testing Specification for Temperature Uniformity in Thermocouple Calibration Furnaces.
The PR322A high-temperature thermocouple calibration furnace is used in conjunction with the PR354 series high-temperature furnace control cabinet. The control cabinet features high-precision temperature measurement, a dedicated intelligent constant temperature algorithm, and multiple protection functions (including power-on slow start, upper limit restrictions on heating power and heating current, self-locking tripping of the main heating circuit, freewheeling protection, etc.). It has excellent power supply voltage adaptability, eliminating the need for an additional high-power AC regulated power supply for the high-temperature furnace. It can be used with the ZRJ series calibration software to realize functions such as remote start/stop, real-time recording, and parameter query and setting.
