The Isotech 4000 Series Portable Temperature Calibrators

The Isotech 4000 series Dry Blocks and Multi-Function Calibrators have recently been renewed. The portable units are suitable for use at different measuring locations or in the calibration lab. Temperature baths are essential for temperature metrology.

Calibration of SPRT’s, thermocouples and other temperature sensors requires a temperature source, such as a liquid bath, a fixed point cell, a blackbody, a temperature oven, a dry block or a specific surface source. Then, using this heat source and a reference temperature meter, a calibration can be performed. The Unit Under Test (UUT) to be measured is compared to the reference meter by comparing both in the same source.

It is important that this source has a uniform distribution, both horizontally and vertically. And in order to carry out an accurate measurement, also an excellent short term stability. Isotech provides baths for both the primary and secondary lab as well as for on-site calibrations.

The uniqueness of an Isocal-6 calibration system is that by using different inserts the function changes. By standard we use a metal insert (dry block calibrator), but there is also a liquid bath insert, a blackbody insert for infrared thermometers, an insert for surface sensors or an insert for ITS-90 fixed points. This gives you a multifunctional temperature calibrator for all your temperature sensors.

Traceable calibration certificates are included with the 4000 series as standard. If required, the standard can be equipped with an optional UKAS accredited certificate. A transport case and calibration software for controlling the 4000 series calibrators and reading of the UUT and reference sensor (advanced series) are optional.

"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."

“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.”
