ACL Staticide ACL 450B, Digital Static Field Meter
ACL Staticide ACL 450B — Digital Static Field Meter | Ionizer-Immune | ESD Survey
The ACL Staticide ACL 450B is a professional-grade digital static field meter (static locator) designed for determining the source and magnitude of electrostatic charges in electronics manufacturing and industrial environments. Its chopper-stabilized circuitry makes the ACL 450B uniquely immune to interference from ionizers — enabling accurate static measurements in ionized work areas where standard field meters give false readings. With a 0 ±20,000V measurement range, 3½-digit LCD display, polarity indication, and HOLD function, the ACL 450B is the go-to tool for ESD surveys, ionizer balance verification, and charge accumulation evaluation.
Includes traceable calibration certificate and carrying case. Requires one standard 9V battery.

Frequently Asked Questions
What makes the ACL 450B different from a standard static field meter?
The ACL 450B uses chopper-stabilized circuitry that makes it immune to interference from ionizers. Most standard field meters are affected by ionizer output and give inaccurate readings in ionized environments. The 450B delivers consistent, accurate measurements even in active ionized ESD workstations — making it the preferred meter for facilities running ionization as part of their ESD control program.
What does the pulsating bull’s-eye indicator do?
The pulsating bull’s-eye proximity indicator guides the operator to position the meter at the correct 1" measurement distance from the target surface. Accurate static field measurement requires a consistent, defined measurement distance — the bull’s-eye indicator makes it easy to achieve repeatable readings without guesswork.
Is a calibration certificate included?
Yes — the ACL 450B ships with a traceable calibration certificate. This is required by most quality management systems (ISO 9001, ANSI/ESD S20.20) that mandate calibrated test equipment. Recalibration services are available through ACL Staticide or an accredited calibration lab.
What is the measurement range and resolution of the ACL 450B?
The ACL 450B measures 0 ±20,000 volts at a 1" (25 mm) distance from the target surface, with a resolution of 100V increments on the 3½-digit LCD display. This range covers virtually all electrostatic charge levels encountered in electronics manufacturing and industrial static control applications.
Can the ACL 450B be used to verify ionizer balance and performance?
Yes — because its chopper-stabilized circuitry is immune to ionizer interference, the ACL 450B is well-suited for ionizer balance checks and performance verification. Proper ionizer balance (equal positive and negative ion output) is critical for effective ESD control, and the 450B’s polarity indication and HOLD function make it straightforward to perform these measurements per ANSI/ESD SP3.3 guidelines.
