All HI-Q Calibrations Performed Per ISO/IEC 17025:2017 (ANSI/NCSL Z540-1-1994)
HI-Q Environmental Products Company offers a calibration and re-certification service for air flow calibrators and air sampling instrumentation.
Standard protocol requires recalibrating air flow measurement devices once or twice per year depending on use and sampling environment. HI-Q calibrates and certifies units against a N.I.S.T. traceable laminar flow element and furnishes a certification of accuracy with each unit.
Re-Calibration service charges vary depending upon the complexity of the service. The table below describes the recertification service ordering information for functioning air flow measurement units. Repair services are also available.
