IET SCA Series Capacitance Standard
IET GenRad 1404 Series Primary Standard Capacitors
Ohm Labs 200 series standards including the 1Ω reference standard
TTMS has an extensive range of electrical standards and supported equipment for electrical metrology.
From Measurement International we have the highest level of resistance: the Quantum Hall system, which realizes the unit of resistance Ohm with an accuracy of <0.02 ppm, with which a direct transfer can be made up to 1 kΩ and 10 kΩ. In each country there is only one institute that uses this kind of standards. In other cases, a set of precision resistors is used to cover the various decades. Replacements of the Thomas 1 Ω with a stability <0.2 ppm/year serve very well as the primary standard for many industrial laboratories. TTMS has a wide range of standard resistors which are used worldwide at the highest metrological level up to practical working standards for secondary laboratories. The range we can cover is from 10µΩ to 10TΩ. Solutions come from Measurement International as well as from OhmLabs, a manufacturer that only focuses on resistors for standard resistors and current shunts. For transfer standards for resistors we also have solutions from IETLABS, which the ESI has taken care of. Besides resistance, there are also standards for capacitance and induction of IETLABS, which, as they say themselves, still develop and produce these in the same way in the GenRad tradition. To support the transfer of the electrical standards to other decades, various measuring bridges and scanners are available.

As an independent calibration laboratory of electrical/electronic temperature and geometric measuring equipment, we and our customers benefit from accurate measurement results and good traceability. This requires good and stable measurement and control equipment. To achieve this, a reliable partner is needed that offers high quality and thinks along with us, and TTMS is such a partner. We have been working in good collaboration with TTMS for many years. Technical problems are challenges for them and questions are answered quickly and adequately. TTMS is pro-active: they always think along with us. They are also customer-oriented, flexible, committed and reliable. They always live up their appointments. Also, they are experts, provide good advice and deliver the right equipment. In short, MetricControl likes to work with TTMS.

I have been doing business with TTMS for years. They offer us good advice, and have a wide range of products to choose from. Before we decide to purchase a product, TTMS allows us to use a demonstration model to experience for a few days whether the product meets our expectations. They think along with us and don't try to sell me just anything. Should it occur, for whatever reason, that there is a defect in the equipment of TTMS, they will follow up with the required service with regard to repair and, if necessary, a replacement. With its service, TTMS invests in a good and lasting customer relationship.
