Isothermal Technology Limited (Isotech) has introduced a new type of precision thermometer, which will be the new world standard for accuracy and stability. Designed for a wide range of highly accurate industrial and scientific calibration applications, the instrument uses a completely new measurement technique to achieve accuracies better than 0.1 parts per million (ppm) – equivalent to 0.0001°C – when used with a standards platinum resistance thermometer (SPRT).

The MicroK is believed to be the only instrument of its type in the world which will work to this precision with all three commonly used sensors, platinum resistance thermometers (PRTs), thermocouples and thermistors. In terms of long term stability, the MicroK achieves literally zero drift for resistance ratio measurements and an annual drift of only 3 ppm for voltage measurements. While utilising sophisticated software and specially developed circuitry, the MicroK is easy to use and has a comprehensive range of built-in features. It utilises on a 6.4-inch VGA colour touch screen as the main user interface, providing a number of graphically presented user options and controls. The underlying operating system is Microsoft Windows CE™ facilitating direct reading of temperature for all sensor types, data logging, export of data into Microsoft Excel™ applications and graphing facilities.

Measurement ‘Best Practice’ guidelines recommend the use of two separate reference thermometers when carrying out temperature calibrations. For that reason the designers of the MicroK have incorporated three channels, enabling users to achieve best practice without having to invest in additional multiplexers. The instrument also includes ‘keep-warm’ current sources to maintain the power in a PRT when it is not being measured. This feature effectively eliminates uncertainty resulting from power coefficients.

WHAT OUR CUSTOMERS SAY

Arnold Memelink

ABB

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

Sasan Rafii-Tabrizi

University of Luxembourg

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
