Play it safe
Measuring instruments used in quality-related applications must be calibrated at regular intervals. Even minimum measuring errors can have a dramatic impact on the safety of plants or systems and on the quality of manufactured products. Numerous standards and directives in a vast variety of industries require quality assurance systems which include regular monitoring and calibration of portable measuring equipment. Product liability legislation also requires perfectly operating measurement equipment for quality-related measurement tasks. Only systematic monitoring, regular calibration and complete documentation helps to protect you against liability claims.
In most cases, "ISI calibration" is sufficient to meet the requirements of the standards and audits (such as ISO 9001).
