MilliK Precision Thermometer


Colchester VT, USA / Southport, UK / Shanghai, P.R. China –?? 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 (4-20 mA) over the range -270 ??C to 1820 ??C.

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.

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

High Accuracy
< ??5ppm for PRTs, ??2??V for Thermocouples and ??1??A Transmitters

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

Designed to Benefit You
The milliK sets a new standard for value, versatility and accuracy. 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.

Built on World Leading Technology
In 2006 Isotech launched the microK range of thermometry bridges which quickly established themselves as the instrument of choice for National Metrology Institutes and Primary Laboratories with innovative features, accuracy and versatility.

In response to industry demands for greater accuracy, the milliK now brings the same design philosophy of the microK to those outside the Primary Laboratory.

Users calibrating industrial sensors in the laboratory, pharmaceutical plants, food and beverage plants, aerospace, power industries and service companies will welcome the milliK as a solution to increase measurement confidence, ensure high accuracy traceable calibration, improve quality as well as ensure safety and lower energy consumption.

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

The milliK is compatible with I-cal EASY and the Isotech range of PRT and Thermocouple Selector Switches, enabling users to build fully automatic calibration systems for up to 32 temperature sensors with the ability to calculate coefficients and print tables and certificates.

Like the award winning microK range, the milliK is all solid state. There are no mechanical relays, switches or potentiometers which would reduce reliability.

Input Connectors
No compromise design ruled out lower cost problematic connectors and the SPRT / PRT inputs are via the highest quality gold plated push / pull self latching circular connectors overcoming the problems seen elsewhere where thermometers have been designed to a budget.

Outstanding CJC Performance and Flexibility
Again, the no compromise design philosophy led to a specially developed rugged thermocouple connector made from alumina and incorporating the same type of platinum sensor as used in Isotech precision probes ensuring optimal cold junction accuracy.

Three CJC modes allow thermocouple operation with internal automatic compensations, external 0 ??C reference systems or the milliK can measure the junction with a probe on an unused channel, useful for automated systems.

Store Probe Data
There is sufficient memory for an almost unlimited number of standard probes, allowing the storing of calibration data for both resistance thermometers and thermocouples. The digital matching of probe data allows the instrument to show the true temperature. The instrument will warn if a probes calibration time has expired.

Data Logging
Older instruments are limited to a maximum number of logged data points, the milliK is limited only by storage space. The internal memory can store more than six months of data, and with a low cost USB Memory stick the milliK can log continuously for a lifetime

Data Management
Probe data and logged measurements can be exported to a USB Memory drive at the push of a button. Additionally the instrument is future proof with future software updates applied from a USB drive.

Connectivity and Communications
With USB host, two serial interfaces and Ethernet it is easy to communicate with the milliK whether it is on the bench next to a PC or remote by using a LAN or WAN connection. These interfaces are fitted as standard. The milliK includes a PC lead and Cal Notepad software.

Open Calibration
The milliK is readily calibrated against resistance and voltage standards. There are no internal adjustments and the calibration commands are simply sent via RS232 or from the front panel (password protected). The procedure is open and fully documented unlike some other instruments where there is no choice but to return to the manufacturer.
