Bespoke Test and Calibration systems

Pressure | Vacuum | Gas Flow | Electrical | Temperature

At Chell Instruments, we have over 40 years’ experience designing and building
high-integrity test and calibration systems for a range of applications.

Our team of mechanical, electronic and software engineers can design and build solutions for your R&D, production testing and calibration.

From building National Audit Standards for gas flow – to measuring the diffusivity and permeability of graphite – there’s almost no challenge we cannot help tackle.

We’ve developed leak rate testers for the nuclear industry and employed materials and surface treatments to allow pressure measurement of extremely hot gas turbines.


Whole-life support of our systems is provided through cross-calibrations with the standards in both our ISO/IEC17025:2017 accredited UKAS calibration laboratory and our UKAS accredited on-site calibration service. As such, downtime is reduced to an absolute minimum.

We deliver:

  • Automated product test and calibration solutions
  • Design and build in accordance with ISO9001:2015
  • Calibration standards to ISO/IEC17025:2017
  • Vacuum calibration systems to ISO3567:2011

Gas Meter Calibration & Production Tools

Since 2017, we’ve developed a range of instruments and systems to assist in the production and calibration of gas meters.

We have developed a variety of production-ready calibration systems – from primary standard through to transfer standard and high-throughput.

Our systems enable the user to demonstrate a clear path of uncertainty for the calibration of their gas meters.

Calibration & Custom Systems

Chell Instruments have produced a range of calibration systems for pressure, vacuum or flow – ranging from multi-application systems bespoke systems for highly specific customer applications.

We have supplied industries including fuel gas meter manufacturers, nuclear energy, pharmaceuticals, gas turbine (jet engine) research and transducer manufacture.

Whatever your calibration requirement, we can help.

Gas Panels

We manufacture gas panels for a wide variety of applications.

We can deliver a range of support from complete designs and drawings, to prototyping and sub-contracted manufacturing – in any quantity or complexity.

Typical manifold technologies include:

  • Fully orbitally welded UHP
  • Welded ‘Microfit’ assemblies
  • Compression fittings
  • Face Seal fittings
