Transcription de la présentation

  1. Introducing the microK Isothermal Technology Ltd microK Slide:1

  2. 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

  3. 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. microK Slide:3

  4. 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 sigma-delta ADC circuits. microK Slide:4

  5. 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

  6. Accuracy • Resolution • Resistance: 0.01ppm of range • Voltage: 10nV on 125mV Range • Stability Voltage • 3 ppm / year microK Slide:6

  7. 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

  8. 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

  9. Three Channel • Three Input Channels • Best Practise Ready • Allows two standards and a device under test to be connected simultaneously microK Slide:9

  10. Easy to Use • Operated by large touch screen display • Intuitive • Can add keyboard and mouse microK Slide:10

  11. Easy to Use • Includes Graphing Facility • Auto or Manual Scales • Intuitive microK Slide:11

  12. Easy to Use • Log Data to Internal Memory • Or USB Pen Drive microK Slide:12

  13. Solid State - Reliable • All Solid Sate • Reliable • No potentiometers • No Dials • No Knobs • No Relays microK Slide:13

  14. microK • A new standard for secondary calibration laboratories microK Slide:14

  15. microK – Further Information • Http://www.isotech.co.uk/microk • Data Sheet • Technical Articles • Article From Cal Lab Magazine • Latest News microK Slide:15

  16. microK • A new standard for secondary calibration laboratories microK Slide:16
