Company Profile

About us – Who are we? – Here’s the gang

STS is an English company, incorporated in 1991 specifically to develop and manufacture training simulators for ionising radiation monitoring instruments. We came from chemistry, engineering, finance and accountancy backgrounds – an ideal combination to allow development of sound business with an exciting range of instruments.

Our first range of simulators was aimed at surface contamination using a combination of chemistry and gas sensing. Instruments by Ludlum, Thermo Electron, Mini , Bichron and Rotem were all developed and substantial sales achieved. For example, the Thermo Electron Electra ( the STS Model 807) has been sold to most nuclear power stations in the UK.

This generated enquiries for survey instrument simulators, which resulted in a product using microwave technology, giving us a simulator which showed excellent Inverse Square Law and materials shielding properties. Saphymo, Thermo Electron, Mini and Bichron simulators as well as dosimeters from MGP and Siemens became popular with many training schools.

Other series of simulators followed, allowing Plumes exercises to be realistically staged and Chemical Warfare monitors to be produced.

Possibly starting as a mental exercise, we began considering unusual fluorescence measurement techniques which led to the SMF2 – the World's first portable spectrofluorimeter. This rapidly found uses in security printing, agricultural research and in very specific river water analysis. Next came the SMF 3, a whole body monitor with applications in the precise measurement of contamination on workers handling toxic chemicals such as pesticides, industrial chemicals and Chemical Warfare agents. The basic SMF 3 technology was licensed from the UK Health & Safety Laboratory.

To support the manufacture of gas detectors for our surface monitoring simulators, we have developed skills in forming, welding and soldering very thin- 10 micron - platinium wire and we now offer this as a service.

Away from work, we relax with scouting, choral singing, geology, hill walking and water colour painting; but even then we are thinking of ways to develop our existing products and how we research and design new ones.
