Air Monitoring
Ultra Compact Mass Flow Meter and Controller Modules with RS485 Interface
The ultra compact mass flow controller MFC 2000 Series modules from Axetris (Switzerland) are now also available with RS485 interface. This allows OEMs to build extreme compact, multi-channel gas mixers, splitters, or even more complex systems.
Due to the extremely high turndown ratio of 1000:1 and more, a very large flow range can be measured and controlled with one single module. Regular mass flow controllers cover a range up from 100:1.
All modules are multi-gas, multi-range capable. The high accuracy and repeatability, as well as the fast response time of platinum- based MEMS sensor allows a very precise control of the gas flow.
The modules are available with calibrations for the following gases: Air, N2, O2, Ar, CO2, He, H2 (more to come) and with ranges 10-3000 sccm (N2 equivalent).
The products of the MFC 2000 series are now used by customers in the following applications: gas chromatography, mass
spectroscopy, thermal analysis, ion mobility spectrometry, leakage measurement, CO2 laser, bioreactors, plasma treatment and thin film coating. In almost all applications, customers could achieve significant performance gains with Axetris MFC solutions. Specific optimised calibration parameters are available for a wide variety of applications.

25479pr@reply-direct.com UKAS Accreditation Maintained
Following technical assessments at their Speciality Gases production sites at Immingham and Morden, BOC (UK) is delighted to announce that they have retained their United Kingdom Accreditation Service (UKAS) accreditation to ISO/IEC 17025 and ISO Guide 34.
BOC has a longstanding accreditation to ISO/IEC 17025 for a wide range of gas calibration mixtures and has progressively extended the scope of accreditation to cover a range of gaseous hydrocarbon mixtures to enable the production and certification of synthetic natural gas and petrochemicals mixtures.
BOC has a longstanding accreditation to ISO/IEC 17025 for a wide range of gas calibration mixtures and has progressively extended the scope of accreditation to cover a range of gaseous hydrocarbon mixtures to enable the production and certification of synthetic natural gas and petrochemicals mixtures.
BOC has also recently gained ISO/IEC 17025 accreditation as a Testing Laboratory demonstrating our focus on quality and development and ‘continuous improvement’.
ISO Guide 34 includes explicit requirements for Request, Tender and Contract reviews, Production Planning and Control, Material handling and storage, Material processing, Metrological traceability and the assessment of homogeneity and stability. ISO Guide 34 enables BOC to specify and include a shelf life period on the accredited Certificates of Analysis for all of our ISO/IEC 17025 gas calibration mixtures.
BOC's UKAS accreditation covers a wide range of products including evidential breath-| analyser mixtures for the UK and Irish police forces, binary mixtures for continuous emissions monitoring systems, MOT exhaust gas mixtures, petrochemical mixtures and natural gas mixtures for fiscal measurements.
