Factory calibration at GTE Industrieelektronik

Your KMG device is in the best hands with us: In our laboratory, the force 

gauges are loaded and calibrated with a defined reference force curve. Our 

reference sensors are regularly traceable calibrated in accredited calibration 

laboratories and meet the highest quality standards. As a manufacturer, we 

know every detail. We calibrate your instrument carefully and accurately. Of 

course, you will receive a factory calibration certificate for each calibration.

An order form is included in the scope of delivery of your KMG-Lite. To place 

an order, send us the completed order form together with your device. GTE 

offers the regular calibration also as a subscription with many advantages.
