New Definitions for the International System of Units
It's official – on November 16th, 2018 scientists from around the world voted to revise the SI. This means that all SI units will now be defined in terms of constants. The definitions of the kilogram, ampere, kelvin and mole will formally change as of May 20, 2019.
The Kelvin will be defined in terms of the Boltzmann constant, rather than the water triple point. While there is a fundamental change in the definition of the kelvin, there will be no noticeable change in the magnitude of the kelvin or °C.
The new definition allows for improved temperature metrology as technology improves, though the value of the water triple point remains unchanged and the use of the International Temperature Scale (ITS-90) will continue with the same defined values and uncertainties.

Official Presentation of the Queen's Award for Enterprise
On Thursday, September 21, the Queen's Lord-Lieutenant, Mr. Mark Blundell, and the Deputy Lieutenant, Mr. John Flamson, OBE,DL, formally presented the Queen's Award for Enterprise to John Tavener, the Managing Director of Isotech. Following a tour of the offices, factory, and laboratory, there was a company celebration. The Lord-Lieutenant and Deputy Lieutenant attended. The Lord-Lieutenant said,
"The very innovative approach in the co-development of a new type of resistance bridge for use in the highest precision measurement applications, and establishing and dissemination of the International Temperature Scale has set the Innovation bar at a very high level. For this, you should feel justifiably proud. A remarkable example of a highly specialized product, which has made your company a world leader in its field."
2017 Queens Award for Enterprise
The award is for the co-development of the microK, recognizing both the innovation and commercial success of this precision Thermometry Bridge.
John Tavener, Isotech founder and President, says, "We are delighted that Her Majesty the Queen has approved the Prime Minister's recommendation that Isotech should receive a Queen's Award for Enterprise in the Innovation category this year... I recognised that the existing instruments used old technology and relied on obsolete components; cooperating with Metrosol Ltd we developed this new device, with better performance and lower cost than the older designs. Winning a Queen's Award for Enterprise; the highest honour that can be bestowed on a UK company is a real cause for celebration for everyone at Isotech."
About the Award
The Queen's Awards for Enterprise are awarded to businesses for outstanding achievement in four categories: International Trade, Innovation, Sustainable Development, and Promoting Opportunity, the last being to recognize businesses who promote social mobility. The award looks not just at innovation and commercial success, but also at the company and its role within the local community, environmental impact and the quality of its relationships with suppliers, partners, employees and customers.
National Conference for Standards and Laboratories
Isotech North America was represented at the National Conference for Standards and Laboratories in National Harbor, MD. This is one of the premier international events where Metrologists gather and share research and knowledge, as well as for manufacturers to present new instrumentation. Of course, Isotech temperature calibration equipment was featured at this event!
New UKAS Article on Benefits of Accreditation
Isotech’s UKAS accredited calibration laboratory was first established in 1983, and has grown into a full-scale laboratory providing calibration to the smallest of uncertainties. This not only ensures our customers receive the best possible calibration service, but also helps maintain Isotech’s position as a global leader in thermal metrology.
UKAS have written a case study illustrating the value of accreditation around Isotech's experience.

Isotech’s MicroK Primary Thermometers excel again in independent reports from National Labs
The MicroK range of primary thermometry bridges is continuing to receive international accolades. In the most recent report from The National Physical Lab (NPL), published in the International Journal of Thermophysics, 14 bridges from different manufacturers were evaluated on linearity and accuracy. All 4 Microks performed at least 4 times better than specification, whilst many other manufacturers barely met or failed published specifications. A strong endorsement of Isotech’s company tag line – Integrity in Calibration.

New MilliK Channel Expander
Following the success of the highly accurate milliK Precision Thermometer Isotech are pleased to introduce the "millisKanner" This eight channel device expands the milliK to create an innovative multi channel system that is unmatched in terms of accuracy and flexibility. Up to four millisKanners can be connected adding 32 expansion channels, each easily controlled from the milliK.
With accuracy to 3mK (0.003°C) and a resolution of 0.0001°C the system can be used with both laboratory and industrial types of standard thermometers, SPRT's, PRT's, Thermistors, Thermocouples. The milliK also supports 4-20mA Process Inputs, the ability to control Isotech Dry Blocks and Baths and virtually unlimited logging capacity.
This thermal metrology equipment is also suited for both calibration laboratories and high accuracy measurements in industrial and scientific applications.
New Resistance Thermometry Bridges Provide Greater Accuracy and Additional Features
for NMI Temperature Metrologists
microK Thermometry Bridges have quickly established an excellent reputation for both measuring performance and innovation.
Customers include National Measurement Institutes (NMIs), Research Organisations
and Accredited Temperature Calibration Laboratories.
The complete range now include a GPIB IEEE interface as well as the earlier serial
and USB interfaces, additionally the microK 70 and 125 have an Ethernet port and
to allow monitoring and control from across a network.
The microK 70 and 125 are ideal for Primary Laboratories with a ratio accuracy of <0.02ppm,
the microK 250 and 500 are ideal for Secondary Laboratory applications with an equivalent
temperature accuracy to 0.06mK, 0.00006C.
As well as Standard Resistance Thermometers the microK range can make high accuracy
measurements from Standard Thermocouples, measuring voltage to an accuracy of 250nV
Quite simply, no other Thermometry Bridge is available that can achieve such high
accuracy SPRT measurements and support laboratory standard thermocouples.
New Product: TTI-10 Thermometer
The new TTI-10 is a high accuracy handheld temperature indicator with two platinum
resistance thermometer inputs. The high precision makes the Isotech temperature calibration instrument particularly suitable as a portable reference thermometer to use alongside Isotech temperature calibrators such as the Fast-Cal, Isocal-6 and Dry Block ranges. It is also suited
for high accuracy measurements in industrial and scientific applications.
New Product: MilliK Secondary Thermometer
New Precision Thermometer for industrial calibration and measurement
- High Accuracy Measurement – to 0.003°C
SPRTs, PRTs, Thermistors, Thermocouples and 4 - 20mA Process Inputs
- Controls Calibration Baths
- Logs Data
Isotech are pleased to announce the milliK, a new Precision Thermometer€“ named
after the unit for one thousandth of a degree Celsius, 1mK, 0.001°C. The milliK
is accurate to 3mK (0.003°C) with a resolution of 0.0001°C.
It can be used with both laboratory and industrial types of standard thermometers:-
SPRTs, PRTs, Thermocouples, Thermistors and process inputs. In addition to high
accuracy measurement, the milliK logs data with virtually unlimited capacity and
can also be used to control Isotech Dry Blocks and temperature calibration baths.
Data can be logged to a USB Memory Drive or internal memory and opened directly
in Microsoft Excel„¢. The large colour display has both numeric and graphical display
modes and facilitates easy configuration of the instrument.
The milliK has three input channels, two for resistance thermometer or thermocouple
inputs and a third input for current transmitters. It is compatible with Isotech's
automatic calibration software and multiplexors.
The instrument can be programmed with a range of data to suit both ITS-90 (SPRT)
and IEC 751 (EN 60751) conversions and there is sufficient memory to store data
for an unlimited number of probes. To ease data entry, a keyboard can be attached
via the USB port.
The milliK is an ideal thermal metrology instrument for calibrating industrial temperature sensors with its ability to measure all sensor types, support Standard Thermometers and to interface with Isotech calibration baths. Other applications of this Isotech temperature thermometer include high accuracy measuring and logging in pharmaceutical, research, scientific, industrial and environmental monitoring.
