• Single Workstation Continuous Monitor
  Continuously monitors the path-to-ground integrity of one operator, one ESD worksurface and the electrical ground of the electrical receptacle used to power the monitor
• Desco Wave Distortion Technology
  Provides stable continuous monitoring (versus pulsed or intermittent) of the wrist strap’s path-to-ground* and the presence of its 1 megohm safety resistor
• Park Snap
  Allows the operator to disconnect (and park) a wrist strap when leaving the workstation without creating a false alarm
• Single-Wire Impedance Design
  Meets ANSI/ESD S20.20 in accordance with ESD TR1.0-01-0
• 1.2 Volt Operator Test Voltage
  Reduces the risk of electrical overstress (EOS) for the handling of sensitive components
• <50 Millisecond Alarm Response Time
  Identifies failures and intermittencies that inferior technologies miss
• Continuous Visual and Audible Alarms
  Illuminates green to indicate proper grounding; illuminates red and sounds audible alarm when intermittent or failed connection occurs
• Relay Box Accessory
  Pairs with the 50547 Relay Box to control external light towers
• Calibration Verification
  Use the Desco 98221 Wave Distortion Monitor Verification Tester to check the test limits of Wave Distortion Monitors without removing them from their workstations
• NIST Calibrated with Certificate Included
  Calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology. For more information on the calibration of Desco products, see Calibration.
• 220VAC Input Rating with UK Power Cord
• Works with standard electrical systems in the United Kingdom and Asia
• Made in the United States of America

*The ESDA Wrist Strap standard is ANSI/ESD S1.1. The Wrist Strap System required limit per ANSI/ESD S20.20 Table 3 is 0.8 to 1.2 x 10⁶ ohms with product qualification testing per ANSI/ESD S1.1. The test range of the monitored circuit is 500 kilohms to 10 megohms.
