Introducing the microK
Isothermal Technology Ltd
microK Slide:1
What is the microK?
 A New Instrument providing
performance better than 1mK
 Manufactured by Isotech
 Designed Exclusively for Isotech
 Not a badged instrument
microK Slide:2
Why is it exciting?
 A great deal, it is the most accurate instrument
in its class, the only instrument to work at this
precision with platinum resistance
thermometers, thermistors and thermocouples.
 The core measurement technology was
developed in conjunction with the National
Physical Laboratory
 NPL and microK has the sole license for the use
of this technology for temperature
measurement.

The A to D
 Uses specially designed analogue to digital converter
used in conjunction with a digital signal processor
(DSP)
 Uses a unique adaptation of existing advanced
sigma-delta ADC techniques to achieve linearity
better than 0.4 ppm.
 A further major benefit of this ADC technique is its
low noise performance,
 reduced by a factor of 32 over conventional sigmadelta ADC circuits.
microK Slide:4
Accuracy
 The microK achieves 0.4ppm over the
whole range
 For SPRTs equivalent to 0.4mK
 For Voltage the specification is 250nV
at 20mV
 Equivalent to 0.01°C for a Gold Platinum
thermocouple at 1000 °C
microK Slide:5
Accuracy
 Resolution
 Resistance: 0.01ppm of range
 Voltage: 10nV on 125mV Range
 Stability Voltage
 3 ppm / year
microK Slide:6
Resistance AND Voltage
 microK supports
 SPRTs and IPRTs
 Thermistors
 Thermocouples
 Only instrument in its
class to do this
 A DVM with comparable
performance has a similar
cost to the microK alone
microK Slide:7
Zero Drift for Resistance
 The microK uses a “substitution
technique” in which the Device-Under-Test
and the Reference are successively
switched
 This means that the stability of resistance ratio
measurements is immeasurably small
microK Slide:8
Three Channel
 Three Input Channels
 Best Practise Ready
 Allows two standards and a device under test to
be connected simultaneously
microK Slide:9
Easy to Use
 Operated by
large touch
screen display
 Intuitive
 Can add
keyboard and
mouse
