Since 1973 ESI has been involved in the development and commercialisation of environmental sensors and systems used in the precise monitoring of water, its presence and movement. The Company's early client base was in salt water (marine) applications. In 2004, ESI made a corporate decision to focus exclusively on fresh water management and applications. The Company is now meeting growing market demand and regulatory requirements for accurate, versatile technologies where water management is critical. ESI also provides sensors and systems on an OEM basis. ESI has adapted its core technology into an exciting new instrument for measuring the water cut in producing oil wells. This technology can be applied in many other applications in the oil and gas and process control industries.
