We recommend calibration of Mark-10 gauges about once per year. High usage may require more frequent calibrations. We are able to provide fast turnaround thanks to a fully equipped climate-controlled calibration laboratory . All calibrations include a NIST-traceable (National Institute of Standards and Technology) certificate.
QCSI certificates are ISO/IEC 17025 accredited and include 10 data points in each direction (tension/compression or clockwise/counter-clockwise).
