The milliK Precision Thermometer from Isotech 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.
The milliK has two input channels for sensors and a third channel for current. It can be expanded to become a measuring system with up to 33 channels reading SPRTs,RTDs, Thermistors, or Thermocouples with the option to control calibration baths and log readings accurately.

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.

Wide Range of Sensors 
SPRTs, PRTs, Thermistors, Thermocouple and 4 - 20mA 

High Accuracy 
< ±5ppm for PRTs, ±2μV for Thermocouples and ±1μA Transmitters 

Logs – Controls Isotech Temperature Sources 
Massive logging capacity – controls Dry Blocks and Liquid Baths 

Benefiting You 
The milliK sets a new standard for value, versatility and accuracy - < ±5ppm over range for PRTs, ±2μV for Thermocouples and ±1μA for current transmitters, see Data Sheet.

Supporting a wide range of sensors and functions it replaces individual devices making a cost effective calibration solution. 
A robust design and operation from AC or DC power allows the milliK to be used in the laboratory, test room or out in the field.

The milliK can display in °C, °F, K, Ohms, mV and mA with numeric and graphical display modes. The large back lit display makes configuring the instrument and setting the scrolling strip charts intuitive. The USB port allows for the use of a mouse, keyboard or USB Drive.

No Compromise Design 
The design team have considered industrial users and applications in order to avoid measurement errors and problems encountered in some instruments from other manufacturers: 

Eliminates Thermal EMF Errors in PRTS 
Fast current reversal technology and solid state switching eliminate thermal EMF effects avoiding the errors that occur with fixed DC instruments. 

Lead Wire Correction 
PRT lead wire errors are eliminated for up to 30m of four core screened cable. 

Galvanic Isolation 
Not only are the two sensor channels galvanically isolated, the 4 - 20mA input is also separately isolated. The benefits of the advance design are no ground loops, improved safety and noise immunity. 

High Resolution 
The display resolution is 0.0001°C (0.1mK) made possible by using a powerful Sigma Delta Analogue to Digital converter to achieve a true measuring resolution of just 28μΩ equivalent to 0.00007°C (0.07mK) for PRT inputs.
