Workstation and Wrist Strap  Monitoring

Continuously monitor your ground connection to  ensure ESDS products handled are safe

  • Are  continuous monitors a requirement of  S20.20?

  • Note: Work surface must have a conductive layer such as Dual Layer Rubber or Dissipative 3-Layer Vinyl or Micastat® Dissipative Laminate with conductive buried layers. Our Continuous Monitors are not recommended for use with homogeneous matting.

    • Control Unit LEDs indicate proper grounding of two mats and two operators; includes mounting
      Allows mounting Control Unit at eye level, not using any work surface area; illuminated LEDs continuously display grounding status
    • Two Satellite Remote Monitors include monitored wrist strap ground, parking stud, and unmonitored ground for guest or equipment
      Versatile design allowing placement where desired up to 7 feet from control unit. Red LED will illuminate, but audio alarm not sound when wrist strap coil cord is snapped on parking stud.
    • Audio alarm
      An audio alarm sounds continuously if the wrist strap coil cord is inserted into the ground jack and not parked
    • Wave Distortion Technology provides real-time monitoring
      Pays for itself - ensures ESD protected workstation, reducing catastrophic failures and latent defects
    • Utilizes reliable wave distortion technology
      Provides true 100% continuous monitoring. Not pulsed current that’s off over 90% of time
    • Can use with any brand of single-wire wrist strap and coil cord components.
      Life-cycle costs of monitor/wrist strap/cord are 66% lower than dual-wire approach
    • Miniscule electrical current required to generate waveform
      No reported case of skin irritation
    • Designed for use by 5 foot tall 90 pound to 6 foot 5 inch 250 pound person
      Individual adjustment for each operator is not necessary
    • Superior warranty
      See details of 5 year Limited Warranty
    • Provided with calibration to NIST traceable standards
      Important for users to maintain NIST calibration at their facility
    • Calibration unit available [See Desco EMIT item 50512]
      Simple and quick means to assure accurate performance and conform with ANSI/ESD S20.20 Paragragh 6.2.2.2. Provides lower calibration life cycle costs.
    • Made in America at our Chino CA facility
      Superior quality
    Note: Continuous Monitors pay for themselves improving quality, productivity, eliminating wrist strap daily testing and test result logging. Per ESD-S1.1 paragraph 6.1.3 Frequency of Functional Testing "The wrist strap system should be tested daily to ensure proper electrical value. Daily testing may be omitted if constant monitoring is used." Per ESD Handbook TR 20.20 paragraph 5.3.2.4.4 "Typical test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, and then continuous monitoring should be considered or even required."

    Note: Work surface must have a conductive layer such as Dual Layer Rubber or Dissipative 3 Layer Vinyl or Micastat® Dissipative Laminate with conductive buried layers. Desco EMIT Continuous Monitors are not recommended for use with homogeneous matting.
