Croydon Precision Instrument Company (Cropico) started with a small assortment of standard resistors, resistor banks, and a voltage ratio bank, in 1952. In the 60s, Cropico expanded its product portfolio, with new products such as the RH9A-4 high resistance decade bank. This was the immediate start of Cropico products’ worldwide export. Steady growth continued throughout the 70s, 80s, and 90s of the twentieth century. Cropico stuck with Croydon during this time, while simultaneously extending their activities through the set-up of engineering design and product development services in Norwich.

One of the developments was an entirely new production platform: accurate measurement of low resistance. The DO4, DO4000, and DO5000 milli ohm and micro ohmmeters series were introduced. In 2006, Cropico was acquired by the Seaward Group, as Seaward was looking for ways to expand its test and measurement industry expertise. Seaward’s continued support for new product development will ensure that the Cropico brand is strengthened, while retaining the leading position as a high-performance technology supplier for industries ranging from automotive and aerospace, to defense and utilities companies.

The current product portfolio includes:
– Resistance Standards & Decades
– Milliohmmeters & Microhmmeter
– Temperature Measurement

WHAT OUR CUSTOMERS SAY

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."

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.”
