We can trace our roots back over 150 years to 1852. Originally known as Negretti and Zambra, the company founders pioneered research into the relationship of barometric pressure and height above sea level using hot air balloons.

Renowned as leading developers of scientific instruments Negretti & Zambra produced barometers, cameras, binoculars, thermometers and meterological instruments often found in antique shops today.

Since the early 1960s we have produced Altimeters, Airspeed Indicators, Airspeed Accelerometers and Indicators, using traditional electro-mechanical technology. This experience enabled us in recent years to focus considerable engineering invention and resource into the development of our current range of avionics products. These innovative designs have received wide acclaim within the industry and have made a significant contribution to the evolution of the modern cockpit.

The current product range harnesses 'Cutting Edge' advanced digital processing and display techniques and calls on our unrivalled qualifications as a supplier of solid-state instrumentation. Individual equipment items have been developed to meet customer driven requirements that fall within our specialist area. To date, this has included: -

	Secondary Flight Display™
