STATICO's S2001PVSK, the Periodic Verification System Kit, is a hand-held alternative to a charged plate monitor. It consists of four components- an Electrostatic Fieldmeter, Model S2001, a Detachable Plate, and a Charger- for measuring static charge and verifying ionizer performance. Used alone, the Fieldmeter measures electrostatic fields on any surface. Ranging lights ensure accurate and repeatable measurements by enabling users to determine the exact distance at which the voltage reading is correct. NIST Certified.
