Introducing the micro. K Isothermal Technology Ltd micro. K Slide: 1

What is the micro. K? o o A New Instrument providing performance better than 1 m. K Manufactured by Isotech n n Designed Exclusively for Isotech Not a badged instrument micro. K Slide: 2

Why is it exciting? n n n 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 micro. K has the sole license for the use of this technology for temperature measurement. micro. K Slide: 3

The A to D o o o 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, n reduced by a factor of 32 over conventional sigmadelta ADC circuits. micro. K Slide: 4

Accuracy o The micro. K achieves 0. 4 ppm over the whole range n o For SPRTs equivalent to 0. 4 m. K For Voltage the specification is 250 n. V at 20 m. V n Equivalent to 0. 01°C for a Gold Platinum thermocouple at 1000 °C micro. K Slide: 5

Accuracy o Resolution n n o Resistance: 0. 01 ppm of range Voltage: 10 n. V on 125 m. V Range Stability Voltage n 3 ppm / year micro. K Slide: 6

Resistance AND Voltage o micro. K supports n n n SPRTs and IPRTs Thermistors Thermocouples o Only instrument in its class to do this o A DVM with comparable performance has a similar cost to the micro. K alone micro. K Slide: 7

Zero Drift for Resistance o The micro. K uses a “substitution technique” in which the Device-Under. Test and the Reference are successively switched n This means that the stability of resistance ratio measurements is immeasurably small micro. K Slide: 8

Three Channel o Three Input Channels n n Best Practise Ready Allows two standards and a device under test to be connected simultaneously micro. K Slide: 9

Easy to Use o Operated by large touch screen display n n Intuitive Can add keyboard and mouse micro. K Slide: 10

Easy to Use o Includes Graphing Facility n n Auto or Manual Scales Intuitive micro. K Slide: 11

Easy to Use o o Log Data to Internal Memory Or USB Pen Drive micro. K Slide: 12

Solid State - Reliable o o All Solid Sate Reliable n n No No potentiometers Dials Knobs Relays micro. K Slide: 13

micro. K o A new standard for secondary calibration laboratories micro. K Slide: 14 Accuracy - SPRT Better than 1 m. K Over Whole Range Channels Three Probes Supported SPRTs, Thermistors and Thermocouples Solid State Design All solid state NO relays or dials Stability 0 ppm / per year Measurement Time 1 Second PC Interface RS 232 and USB Units Ratio, V, °C, °F and K
