Chell Instruments offer a wide range of high quality and reliable mass flow meters, controllers and systems suitable for use in a wide range of applications and industries.
With over 40 years of experience in flow measurement and control, we are extremely well placed to assist in specifying and supplying instumentation for your application, from single instruments to bespoke automated systems. Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
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
Chell Instruments offer a wide range of high quality and reliable vacuum measurement instrumentation for use in a huge variety of applications and industries.
With over 30 years of experience in vacuum measurement and control, we are extremely well placed to assist in specifying and supplying instrumentation for your application, from single instruments to bespoke automated systems.
Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell has created a range of precision needle valves capable of repeatably delivering precise flows. The valves range from 0-20sccm to 0-3slpm .
All feature stainless steel construction with Perlast® seals (other seal materials are available) and a variety of fitting/flange options.
The Mechanism range of stainless steel needle valves, developed by Chell Instruments, provide the finest gas flow control over typical ranges of 0-20, 0-1000 & 0-3000 std.cm3min-1 air at 1bar differential pressure. Designed for use in pressure or vacuum applications, they are ideal for use in gas analysers, chromatographs and mass spectrometers – in addition to any application where fine gas flow control is required.
The valve’s opening characteristics are extremely smooth, preventing bursts of gas which would disturb delicate or Ultra-High Vacuum instrumentation.
Construction is in Stainless Steel, with Perlast® perfluoroelastomer body seals and a Fluorosint® orifice seal, for the best corrosion resistance. Vacuum rated valves are leak tested on a helium mass spectrometer to
Valves are available with 1/16in single ferrule or 1/8in, 1/4in or 6mm twin ferrule compression fittings and additionally, vacuum models may be selected with NW10KF fittings. VCR fittings are also available and custom fitting types (including all welded) can also be accomodated.
The Mechanism Valve was developed specifically for mass spectrometry inlet service, probably the most critical application for such a valve but is eminently suitable for many other demanding applications where long-term stability is required
