The Isotech Rugged Dry Block Calibrators are designed for US Navy requirements and meet stringent military standards. The design withstands demanding environments, and is drop and water resistant. The series consists of two models.

Low and High temperature units

The Isotech Low Temperature Rugged Calibrator 786 and the Isotech High Temperature Rugged Calibrator 787. Unlike other calibrators that cannot be used in extreme cold, Isotech’s Low Temperature Rugged Calibrator 786 features an environmental control system, which is specially tuned for calibrations in cold rooms and freezers down to -29°C. The Isotech Low Temperature Rugged Calibrator 786 has a range of -40°C to +140°C. Conversely, the Isotech High Temperature Rugged Calibrator 787 can again be used in warm environments from 0°C to 50°C. This unit has a temperature range of 35°C to 660°C.


Both models are configurable in a Basic, Site or Advanced model.
The Basic model for quick and easy testing using an external reference temperature gauge.It can then be chosen, for example, to do this with a TTI-10, TTi-22, milliK or microK from Isotech.The Site model comes with a built-in reference temperature meter and an optional reference temperature probe.
The Advanced model comes with an extended controller and three additional temperature measurement channels. This unit is equipped with a LAN interface and can also run a sequence of temperature settings where temperature measurements can be stored in internal memory or a USB memory stick. Testing temperature switches is also possible with this unit.

For detailed specifications, please refer to the datasheet of the 786 and 787.

"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.”
