NEWS

	2010-01-05 ISO/IEC 17025:2005 Polycontrols calibration lab recently achieved ISO/IEC 17025:2005 accreditation. An international standard for evaluating the competence of calibration laboratories. This breakthrough achievement makes Polycontrols the first, and currently the only organization in Canada, to provide ISO/IEC 17025:2005 accredited calibration for gas flow measurement. ISO/IEC 17025 is considered by the calibration industry as the ultimate recognition of competence. This standard encompasses the entire calibration system and produces metrics for the calibration rig co ... mponents, administrative systems for process operations, personnel proficiency, documentation supporting the traceability and total measurement uncertainty for the entire calibration facility. ISO/IEC 17025 standards ensure the highest level of confidence in accuracy and repeatability. Read more Archives

Standards & Uncertainties

Information

Standards & Uncertainties

Our laboratories are equipped with the most recent technologies and allow us to calibrate each instrument under its own specific operating conditions over the following ranges:

Gas calibrations within a range of 5 sccm to 6000 slpm, air or nitrogen equivalent
Liquid calibrations within a range of 0.378 kg/min to 189.27 kg/min

To ensure the highest possible accuracy, our installations are equipped with the following calibration fluids:

Standard calibration gases include: Air, N₂, Ar, He and H₂
Standard calibration fluids include: Water, MIL-C-7024 T2 and Oil (BP 2380)
