City Spin-out: City Technology Ltd

City Technology Ltd is a spin-out company from City, University of London. Based in Portsmouth, Bonn, Poole and Shanghai, the company now employs over 400 people globally. In March 2006 City Technology became part of Honeywell – a $26 billion diversified technology company employing 120,000 people in 95 countries around the world. City Technology is Honeywell's leading brand for gas sensors.

The Challenge

To develop a gas sensor for gas detection equipment used to protect people, property and the environment from the hazards of dangerous toxic and flammable gases.

The Solution

City Technology was founded in 1977 by four City scientists, John Finbow, Brian Hobbs, Tony Tantrum and Robert Chan Henry whose work focused on exploitation of novel oxygen sensing technology developed by City's Wolfson Institute for Electrochemical Technology.

The young company developed the galvanic oxygen sensor, the technology that can be used in industry to monitor potentially dangerous conditions arising from oxygen deficiency or excess.

City Technology now leads the global market in the development, design and manufacture of innovative gas sensors and sensing technology employed in safety critical gas detection equipment.

City Technology has won a host of prestigious prizes, including the coveted Queen’s Awards for Technological Achievement, Technology and Export Achievement.
