  • Patent number: 11959814
    Abstract: A high temperature dry block temperature calibrator relates to the technical field of temperature calibration. The high temperature dry block temperature calibrator includes a high temperature furnace, a control board module, a system board module, a measuring board module, a lower support, and a housing. The high temperature furnace and the control board module are mounted on the lower support. The system board module and the measuring board module are mounted on the front side surface of the housing. The housing is clipped to the periphery of the lower support and the high temperature furnace and the control board module are accommodated in the housing. The modules are independent of each other and can be removed separately, thereby facilitating maintenance and replacement. The high temperature dry block temperature calibrator can be used for calibrating the temperature of a high temperature element to be measured.
