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

We don’t buy measuring instruments, we purchase solutions for specific measurement problems. I like to buy from TTMS, given their knowledge of test solutions in power electronics. I hate sellers. TTMS helps us to make the right choice. They even come up with instrumentation from manufacturers they do not represent themselves. And always with the perfect service: they are not complicated and just arrange what is needed.

In my role within the calibration and quality lab, it is a continuous striving for quality for me. In order to ensure this, the right support from, amongst others, suppliers is essential. TTMS understands this like no other, and I have been doing business with them for years. If I need to describe the business relationship with TTMS, it would be that it’s both constructive and instinctive. The measurement instrumentation is reliable. In addition to this, TTMS’ expertise of test and measuring equipment complements the STCA.
