For this purpose, the esz AG cooperates with the renowned microphone manufacturer Microtech Gefell GmbH.

With over 200 accredited measurands from all technical fields, the esz AG is one of the largest independent metrology laboratories in Europe. The calibration service provider from Eichenau near Munich is continuously developing this portfolio.

In order to be able to offer its customers further measurement quantities, the esz AG is breaking new ground and cooperating with the microphone manufacturer Microtech Gefell.

Microtech Gefell manufactures high-quality microphone capsules and condenser microphones for audio and measurement applications.

The beginnings of measurement applications date back to 1937, when the Rel mph 9 Tz 20 capsule, also known as the "railway capsule", was manufactured for a Siemens & Halske measurement microphone.

Today’s services include not only microphone production but also the calibration of microphones in the company’s own DAkks-laboratory.

The company is accredited for acoustic measurands as well as for the mechanical measurand "acceleration" according to DIN EN ISO/IEC 17025:2018.

The cooperation between esz AG calibration & metrology and Microtech Gefell provides for accredited calibrations of these measurands to be carried out at Microtech in Gefell, on behalf of esz AG.

The two cooperation partners want to examine how they can use the esz software solution "calibration expert" for this purpose. This would ensure seamless integration and documentation in esz AG’s quality management. The esz software "calibration expert "supports calibration technicians, engineers and metrologists in the calibration and creation or handling of calibration certificates.

"We are looking forward to the cooperation with Microtech Gefell GmbH," explains Daniel Herrmann, Managing Director Sales & Marketing. "The cooperations enable us to offer our customers additional calibrations for the areas of sound level measurement, acceleration sensors and microphones. With Microtech Gefell, we have been able to gain a strong partner for this, who, like esz AG, stands for first-class quality, highest precision and outstanding service."
