The SPMK3000-6(A) Thermocouple Calibration Furnace boasts excellent performance, employing a separate design for the temperature controller and furnace body, resulting in a smaller size and lighter weight. It is suitable for various working environments such as instrument workshops, metrology rooms, and calibration laboratories. It primarily calibrates temperature elements (thermocouples, platinum resistance thermometers, thermometers), temperature transmitters (sensors), temperature switches, and temperature-related instruments, and is widely used in indial and mining enterprises, research institutions, universities, military industries, and metrology departments.
