As Tensitron is the original manufacturer of its products, service and calibrations performed by Tensitron on its tension measurement instrumentation are in compliance with QS-9000 and ISO-9000 standards and requirements. Certification of Tensitron's calibration weights meets the requirements of ISO Guide 17025 and are directly traceable to N.I.S.T.

Per ISO-17025, calibration intervals for our certified weights are to be determined by Tensitron, the user. Upon the advice of the Measurements Standards Division of the State of Colorado Department of Agriculture, we have established this interval at five years from the date of the last inspection. Therefore our next scheduled recertification is to be completed by November 8, 2009.
