Features

·         Single Station Continuous Monitor for Operator, ESD Work Surface, and the Operator’s Electrical Ground Continuously monitors ground integrity of a single operator, ESD workstation and the electrical ground that the monitor is connected to. Eliminates the need for periodic testing and record keeping.

·         Wave Distortion Technology Provides Real-Time Continuous Monitoring for Operator Path to Ground and Presence of 1 Meg Resistor True continuous monitoring (versus pulsed or intermittent) of wrist strap functionality and operator safety according to accepted industry standards.

·         Park Delay Feature Allows operator to disconnect wrist strap cord when normally leaving the workstation without audible (false) alarm sounding.

·         Dual Status LEDs and Audible Alarm for Operator and Workstation Monitoring LEDs illuminate (Green) when operator, work surface, and electrical grounds are functioning correctly. visual alarms activate instantly when a failure occurs, alerting user and supervisor of problem, allowing immediate corrective action.

·         Alarm Signal Use with an external relay (see relay box item 50547) to control access to equipment or other accessories.

·         Use with Single-Wire Wrist Straps. Includes Desco Wrist Strap 09070

·         Calibration Unit Available for Accurate Performance and Conformity Testing in the Field. See Desco Item 98220

·         NIST Calibrated with Certificate Calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology. For more information on calibration of Desco products, see Calibration

·         Made in the United States of America
