Clamp meter brand VOREL 81801.

Universal clamp meter is a digital measuring device designed for measurements of various electrical quantities. In the case of some measurement values, the meter can choose the range itself depending on the measurement result. The meter has been equipped with measuring clamps, which
allow you to measure the AC current in a single wire using the induction method. Thanks to this, it allows the measurement of much higher current intensity than in the case of conventional electric meters. It also allows you to measure the following parameters:

alternating voltage: U a.c. 0-450V
DC voltage: U d.c. 0-600V
alternating current: I a.c. 0-400
resistance: R 0-200 k
diode test: IF 1 mA
the audible signal allows easy verification of the continuity of the circuit
The clamps open up to 25mm and enable the measurement of a wire with a maximum diameter of 19mm.
