Bronkhorst Calibration Centre

ISO/IEC 17025:2005 accredited

The Bronkhorst Calibration Centre is accredited ISO/IEC 17025:2005 by the Dutch Accreditation Council (RvA) under registration number K 127. Herewith is certified that our laboratory’s Quality Assurance system, calibration methods and technical competences have been inspected and audited and meet all necessary requirements.

See ISO/IEC 17025:2005 certificate

Gas flow meter / controller calibrations and adjustments

All Bronkhorst instruments are factory calibrated using highly accurate calibration devices, traceable to (inter)national standards. In addition, accredited calibrations may be required for various reasons, e.g. to meet specific demands from authorities, or for instruments that will be used as reference standards. With more than 30 years of calibration experience Bronkhorst decided to establish a calibration laboratory and apply for accreditation in the field of mass flow and volume flow gas calibration.

Upon accreditation in 2010, calibration services, including adjustments, can be offered in the range of 0.7 ml_n/min up to 6200 l_n/min for both new and existing Bronkhorst gas flow meters / controllers and gas flow calibration devices. In addition the calibration centre can also perform gas flow calibrations for volumetric type of flow meters and other brands of mass flow meters/controllers.
