The Model 511 is a high-quality, portable, chopper-stabilized, non-contacting electrostatic field meter designed for measuring and auditing electrostatic fields in ESD sensitive areas so that operators can find them before they become a problem.
The Model 511 can also be used for testing balance and ± decay capablilities of ionizers when the optional Ionizer Test kit （which includes the Model 511，the Model 511-CP charge plate and the Model 511-CH Charger）is ordered.
Available for use as a Field Meter and for testing balance and +/- decay capabilities of ionizers (with
the optional Ionizer Test Kit)
Push-button “auto-zero” feature removes any offset voltage
Compact, pocket size
Easy-to-read LED display
Distance ranging system utilizes LEDs to indicate a 1-inch spacing between the
instrument and the test target
Hold function allows the user to hold a display when a measurement is being
taken in a location where ready the display is difficult
Chopper-stabilized probe technology allows for use in ionized environments
