About Fischer Messtechnik
Fischer & MAL Elektronik GmbH is a medium-sized company based in Mittenwalde near Berlin that has been engaged in measurement and testing technology since 1984. Its field of specialization is resistance measurement in the high- and low-ohm range. The portfolio includes precision resistance meters for surface, volume and leakage resistances, measuring electrodes (guard-ring electrodes, hand electrodes, textile electrodes, liquid and powder electrodes, Kelvin clamps, four-pole electrodes), high-ohm shielding chambers, glow-wire testing devices for GWFI/GWIT/GWT according to DIN EN 60695-2, tracking (CTI) testing devices according to DIN EN 60112 as well as calibration resistors and calibration boxes. In addition, the company offers calibration of measuring devices and electrodes in the high- and low-ohm range. The products are used in materials and materials research, material development, quality assurance, production, in laboratories and testing institutes, in the cable industry as well as in aerospace. Measuring electrodes are manufactured, among other things, from stainless steel (V2A) with gold-plated precision contacts; production takes place in Germany.
