Industrial calibration

Industrial quantities

Electrical instruments and test equipment can be found in almost every industrial manufacturing or working company. The Industrial Calibration department at esz AG calibrates most quantities and calibration objects in the DC and low-frequency range.

Multifunction calibrators for current, voltage and resistance, oscilloscope calibration stations, counters, signal generators and, of course, high-resolution multimeters are used for this purpose. Our measuring stations for standard electrical quantities and standard electrical technology  enable precise calibration of the most common instruments used in industrial measurement technology.

Electrical calibrations have been an integral part of the esz AG laboratory since 1980. At that time, as a service laboratory still specialising in the calibration of repaired devices, the company worked very early on with high-end calibration techniques and the first AC/DC calibrators, the use of which had previously only been reserved for the military, aviation and medical technology.
