OVERVIEW

Founded by the present directors in 1971, Stroud Instruments Ltd. designs, manufactures and supplies high quality measurement, control and display instrumentation for the process control industry.

We offer a wide range of competitively priced analogue and digital instrumentation for use wherever process variables require to be monitored, displayed, conditioned or controlled. Our products include digital indicators, signal conditioners, signal isolators, resistance transmitters, power supplies and trip amplifiers for installation front of panel, rear of panel and in the field.

The majority of our design activity is directed towards the development and improvement of the product range. However we are proud of our outstanding service in response and support of customer specified design requirements.

The aim of our company is to maintain and improve upon the high standards of quality and reliability of the products we provide and that are demanded by the industry. Stroud Instruments products are designed to comply with current EC directives and their associated national standards and regulations. Our development processes include testing to verify compliance, using outside test laboratories for confirmation where appropriate.

The quality and reliability of our products have assured our status as approved supplier to UK water companies, electricity generators, Environment Agency, etc. Other customers include the petrochemical, pharmaceutical, instrumentation engineers and companies who specialise in instrumentation and control cubicle construction, factory automation and systems installation.

We export world-wide, including to the Irish Republic, Portugal, Norway, Malaysia, Australia, Africa, the Middle East, the Far East, USA and Canada.
