The Isotech milliK Precision Thermometer sets a new standard for the high accuracy measurement and calibration of Platinum Resistance Thermometers, Thermistors, Thermocouple and Process Instrumentation (4-20mA) over the range -270°C to 1820°C.

In addition to low uncertainty measurements from Reference Standards and Industrial sensor measurement 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 accurately.
