Portable Charged Plate Monitor
Operation and Maintenance Instructions
Description
The Desco 19494 Portable Charged Plate Monitor (CPM) is a handheld meter designed to
check the offset voltage and discharge times of air ionizers per ANSI/ESD SP3.3 and ESD
TR53. The meter’s integrated timer measures decay rates from ±1000V to ±100V to determine
the ionizers’ ability to neutralize both positive and negative electrostatic charges within the
coverage area. The 180-degree rotary head with 2.75
ʺ
x 1.25
ʺ
plate allows the operator to
read the display at various angles. The Portable Charged Plate Monitor is calibrated to NIST
standards and include a certificate.
