About Us

Chell Instruments

Industry-leaders in pressure, vacuum and gas flow measurement and control for five decades
Designed by engineers for engineers

Established in May 1976, Chell Instruments is a UK and global leader in gas measurement and control equipment.

Our technology is used at the cutting edge of both research and manufacturing, within industries including aerospace, motorsport, pharmaceuticals and energy.

In many instances, our unique product range has been developed in direct response to the needs of our clients. Our products are designed by engineers for engineers.

Some products have featured in our range for over 40 years – with continual development, innovation and improvement keeping them ahead of the curve.

Our commitment to multi point pressure scanning applications – particularly the aerodynamic testing of Formula 1 cars and development of gas turbines (jets) for aerospace – has resulted in our specialist data acquisition (DAQ) systems.

Our products are manufactured in our UK manufacturing operation using CNC machining, TIG welding, clean areas and helium leak testing to provide us with total control over quality and performance.

Many of our solutions incorporate components produced by partners with whom we have had very long-standing relationships.

Our ISO17025 accredited UKAS calibration facility has some of the lowest uncertainties available so that products purchased from us have the highest measurement integrity.

In 2020, we became part of SDI Group (formally Scientific Digital Imaging) which owns more than fifteen companies who design and manufacture products for use in imaging, sensing and control applications.
