Model 775 Handheld Electrostatic Fieldmeter, 9 VDC
The pocket-sized Simco-Ion Model 775 Handheld Electrostatic Fieldmeter is designed to locate and measure static charge potentials on products, people, equipment, and packaging. The Model 775 Fieldmeter uses a non-contacting, chopper stabilized field sensor and a ranging light mechanism to ensure correct measurements of electrostatic fields in all areas, even using air ionization.
