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

Hypex Electronics

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.
