The New MicroK Precision Thermometer Offers Unrivalled Accuracy, Stability & Versatility

The microK family of precision thermometry bridges use a completely new measurement technique to achieve accuracies to better than 0.02ppm.

With four models to suit all levels of temperature metrology from National Measurement Institutes to those wanting a solution to make low uncertainty temperature measurements in a range of applications.

In addition to making the best resistance measurements the microK makes high accuracy thermocouple measurements with a voltage uncertainty of <0.25ěV. The microK can be used with all standard thermometer types including SPRTs, Standard Thermocouples, Industrial PRTS and thermistors.

First introduced in 2006 the microK has proven use at the world’s leading NMIs and many commercial laboratories. After years of experience and success we now introduce new models with even better performance and new features. All microK models now include IEEE-488 General Purpose Interface Bus as well as RS232 and USB. The microK 70 and microK 125 also feature an Ethernet port and can be monitored and controlled across a LAN.

The MicroK continues to receive international attention as another Isotech development that allowd temperature metrologists world wide to achieve better measurements easier!
 
 
Key Features Performance by Design MicrosKanner
 
What are the advantages
of the microK over

conventional ratio

bridges?

 

Can work with thermocouples

as well as resistance thermometers

 

Simple Touch Screen operation with easy to use interface and data logging options

 

Can connect USB Memory Stick, Keyboard, Mouse

 

Built in database for all your thermometers and reference resistors

 

The microK does not use tapped transformers restricting its measurement range

 

Wide range of resistance, 0 - 500 kΩ

 

No Moving Parts

 

Displays Temperature, Resistance and Ratio

 

Statistical Mode & Chart Display

 

Plug and Play Channel Expanders, control up to 92 channels from the touch screen

 

No PC needed, the display can show temperature and resistance in addition to ratio

 
“Performance by Design” was the
mantra and passion behind the

development of the microK. On Day

1 a decision was made, “ no tweak

pots” (such as used on AC Bridges

to correct for flux leakage), no

software adjustment, no “self calibration”

but performance by design.
 

The microK achieves its resistance

ratio accuracy by design, not

adjustment and is uniquely drift free.

 
To be clear, as a ratio bridge the

microK is drift free. This is a benefit

of the substitution topology used and

provides one of the microK’s most

exciting features, it is inherently drift

free.
 
The microK realizes its superior
linearity and low noise through a

number of novel approaches,

including a new noise reduction

technique, new solid state switching,

new guarding arrangements and a

sophisticated substitution topology

to achieve zero drift.

 
So perhaps it will be of no surprise

to learn it also uses a new type of

ADC, the concept for the core ADC

technology was licensed from NPL

(the UK’s national standards

laboratory) and operates under

NPL’s “Technology Applied”

scheme.

 
The MicrosKanner replicates the input

system of the microK for all 10 of its

input channels. Measurements made

with a microsKanner are therefore to

the same uncertainty as the microK

itself. A microK system can be

expanded to a maximum of 92

channels without losing

measurement performance.

 
The use of plug-and-play technology

means that the extra channels appear

automatically on the microK when you

connect it to a microsKanner.
