GMC-I Messtechnik GmbH  27
During recalibration* in an accredited calibration laboratory 
(DIN EN ISO/IEC 17025) the deviations of your instrument in relation to 
traceable standards are measured and documented. The deviations 
determined in the process are used for correction of the readings dur-
ing subsequent application.
We are pleased to perform DKD or factory calibrations for you in our 
calibration laboratory. Please visit our website at

By having your measuring instrument calibrated regularly, you fulfill the 
requirements of a quality management system per DIN EN ISO 9001.
