We perform ISO-17025 compliant calibrations of gas dividers, CFO kits as well as venturis and mass flow meters (MFC's). In addition to gas flow, our labs are also accredited for temperature and pressure sensors.
Our services range from a pure inspection to a so-called all-inclusive service, which covers necessary repairs in addition to calibration and maintenance. If the measured values are outside of the specified tolerances, an appropriate adjustment can be made.
A standard or ISO 17025 calibration certificate certifies that the calibrated device is working properly within the specified tolerances.
