Static voltmeter "inno"

Demonstration meter for measuring high electrostatic voltages, unlike mechanical electroscopes, this instrument delivers exact and clear quantitative readings as well as the polarity of the charge, the value measured can be frozen using the hold switch, this instrument is easy to transport and can be mounted magnetically, the 26-mm LED display allows readings to be taken from a distance
