Home » Products » Ohm Labs 2000 low resistance standards
The Ohm Labs 2000 low resistance standards are designed as primary laboratory references for maintaining the unit of resistance below 1 ohm. Based on recent progress in material processing, these standards have been developed to ensure good long-term stability. Models 2000, 2001 and 2002 (1 ohm, 0.1 ohm and 0.01 ohm) have a nickel alloy element. With careful heat treatment low temperature coefficients can be realized. The standards are placed in a hermetically sealed housing to be relatively immune to changes of ambient temperature and relative humidity.
You can use these models in oil at a constant temperature of 25°C or in air at 23°C. Models 2003, 2004 and 2005 (1 milli-Ohm to 10 micro-ohm) are made with Manganin alloy elements. They are fixed in a perforated jug for better heat dissipation. These models are recommended for use in stirred oil at 25 °C. All models are supplied with ISO 17025 accredited calibration including temperature coefficient data. The 2000 series are available for intermediate values by special order.

"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.”
