Handheld battery operated fault loop impedance meter

Sonel MZC-20E is a straightforward and comfortable short circuit loop impedance meter.
The precise measurement of short circuit loop impedance in electrcial networks with various voltage ratings is possible with the tiny MZC-20E meter. This equipment allows measurement in electrical networks with voltages up to 440 V. Installers and test engineers working in single- and multi-family homes, office buildings, manufacturing facilities, and other structures with low-voltage electrical installations will find the gadget particularly helpful. Furthermore, the device is ideal for electrical maintenance services. For any application, it always ensures efficient operation and high accuracy of the measurement. Another benefit of this instrument is that, because to its extremely durable shell, it can function even in unfavorable weather circumstances. Despite its small size, the meter does its job perfectly and works well when instantaneous, precise measurements are needed.
