Edwards High Vacuum International
 

Edwards High Vacuum International, a world leader in the design and manufacture of vacuum systems and components, has been supplying vacuum measuring instruments around the world for over 35 years.

The company's mission statement is; "to excel as the world's leading supplier of vacuum equipment by providing advanced technology and services of the highest quality which ensure long term customer satisfaction and acclaim". Certainly, Edwards has always been at the forefront of measuring instrument developments: in the mid 1980's the 1000 and 2000 series were launched, the first microprocessor based vacuum gauge controllers. In the last few years Edwards has led the way with probably the most significant advance in vacuum measurement yet with the introduction of a range of Active gauges, displays and controllers.

The acquisition of Datametrics Inc during the '80's broadened the Edwards range of vacuum measuring and controlling instruments. Edwards remains committed to research and development in the field of vacuum measurement and will continue to harness new technologies by creating innovative new products to meet the changing requirements of its customers.

Chell Instruments is the specialist distributor for these precision vacuum measurement and control products and provides full repair and calibration facilities in the UK.
