In addition to low uncertainty measurements from Reference Standards and Industrial sensors, the milliK can control Isotech temperature sources, sequencing through a programmable list of temperature set points and log data to internal memory or a USB drive. The milliK forms the hub of a measurement system, reading SPRTs, RTDs, Thermistors, Thermocouples and 4 - 20mA current inputs with the option to control calibration baths and log readings.
