Chell Instruments are the UK distributor for the 'SAES Pure Gas' range of gas purification equipment. These offer incredible purification performance over a huge range of gases and flow rates through the use of absorber, adsorber, catalyst, heated getter and palladium membrane purification technologies.
We also supply a range of gas handling solutions, from full, bespoke gas panels to high performance needle valves and regulators.
Chell offer a wide range of equipment for the measurement and control of gas pressure. This could be a very high-end primary pressure standard, benchtop calibrator, portable calibrator or simply a single transducer. We can also provide bespoke, automated pressure measurement systems tailored to your exact process requirements.
Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell supply a range of temperature scanners to complement the pressure scanners

The THI Mass Flow 300 Metaline Series meters and controllers are designed to accurately measure mass flow without corrections or compensations for gas pressure and temperature. They are accurate to better than ±0.75% of full-scale for .005 to 10 slm and ±1.0% of full-scale for 10 to 25 slm. THI mass flow instruments do not require any periodic maintenance under normal operating conditions with clean gases. No damage will occur from the use of moderate overpressures (~500 psi) or overflows. Instruments are normally calibrated with the appropriate standard calibration gas (nitrogen), then a gas conversion factor (GCF) is used to adjust the output for the intended gas. Special calibrations for other gases, such as oxygen, helium and argon, are available upon special order.
