mK Grade High - Precision Thermometer Readout

    The DTMC-mK301 is a new-generation, multi-channel, ultra-high-precision thermometer readout developed for temperature metrology and calibration. It integrates high-accuracy electrical measurement technology, intelligent interface design, and application-specific functions to fully meet the calibration needs of both laboratories and fieldwork. The DTMC-mK301 measures: standard and industrial RTDs, thermocouples, thermistors, temperature transmitters, humidity sensors, DC current, resistance, and voltage signals. It supports ITS-90 and IEC 60751 standards and features built-in thermophysical conversion tools, intelligent sensor management, and broad compatibility across industries such as power, petrochemical, metrology, metallurgy, biotechnology, pharmaceuticals, and scientific research.
