The Desco 19494 Portable Charged Plate Monitor is a handheld device that checks the offset voltage and discharge times of air ionizers per ANSI/ESD SP3.3 and ESD TR53 standards. Its integrated timer measures decay rates from ±1000V to ±100V with a precision 180-degree rotary head and 2.75" x 1.25" plate that allows readings at any angle. Calibrated to NIST standards, this monitor delivers reliable and accurate results.
