Introduction
mK High Precision Thermometer is a new generation of multi-channel super thermometer developed for the field of temperature measurement and calibration and precision temperature measurement. It integrates high-accuracy electrical measurement technology, intelligent interactive technology and industry needs to fully solve the measurement and calibration needs of laboratory and field temperature sensors.
mK high precision thermometer can measure thermal resistors, thermocouples, thermistors, temperature transmitters, DC current and DC resistance, and DC voltage signals. It supports ITS-90 temperature scale and IEC60751 standard, has built-in thermal conversion software, supports sensor parameter management and intelligent sensor management functions, and has a wide range of uses in power, petrochemical, measurement, metallurgy, biopharmaceuticals, scientific research and other work. It is an ideal choice in the field of temperature measurement and calibration.
