The Simco-Ion 775 PVS is a handheld electrostatic fieldmeter system designed for precise surface voltage measurements in ESD-sensitive environments. This portable instrument measures electrostatic fields on surfaces and equipment, functioning as an alternative to charged plate monitors. The complete system includes the Model 775 fieldmeter, Model 775P detachable plate assembly, and Model 775C charger for ionizer verification.
