Medium temperature thermocouple comparison calibration device KT-F311H
horizontal furnace(Japan Only)

The KT-F311H is a thermocouple comparison calibrator that supports up to 1250°C.
They are used in semiconductor processes, aerospace and other fields where high accuracy temperature control is required.
Three-zone split control maintains uniform temperature distribution in the furnace for extended stability.
In addition, in combination with the standard R thermocouple C800-35 or the dedicated measurement unit (sold separately),
Build a traceable calibration system.

  • Thermocouple comparison calibration up to 1250°C: Effective for maintaining the accuracy of thermocouples in the semiconductor, aerospace and defense, and automotive markets
  • High stability: 3-zone division control ensures uniform temperature distribution and long-term stability
  • RS-485 communication allows monitoring of load status

    Application Examples

    This is an example of a temperature calibration system configuration for calibrating general thermocouples.
    The reference temperature sensor and the sensor to be calibrated are maintained at the same temperature in a horizontal comparison calibration furnace, and their indicated value are compared.

    The signal from the sensor is processed by a high accuracy temperature converter and sent to a computer as digital temperature data.
    The temperature calibration software can automatically record data and output a report for each sensor.

    Furthermore, by combining external data recording equipment,
    It also records equipment operating information such as furnace temperature and heater voltage and current values, allowing for more detailed management and analyzing.
