With the handy MZC-20E, short-circuit loop impedances in networks with various rated voltages can be precisely recorded. The device enables the testing of mains voltages up to 440 V. It is ideally suited for installers and measurement technicians in single- and multi-family houses, office buildings, industrial plants as well as other objects with low-voltage systems. Even during maintenance work on electrical systems, the Miernik MZC-20E demonstrates its reliability. Thanks to its robust housing, it is ready for use even in adverse weather conditions. Despite its compact size, it delivers fast and accurate measurement results and is thus a valuable aid wherever precise short-circuit measurements are required.
