  • PDT-740B Static Decay Timer
    Measure decay times for ionizers and materials
    • Designed to measure the time required for a 1,000 volt charge to dissipate to less than 100, 50 or 10 volts in tenths of a second.
    • Used to evaluate the static decay capabilities of materials, personnel, equipment and other products.
    • Compatible with most portable CPM's and field meters having an analog output of ± 2 (10,000 volts equals 1 volt).
    • Used in conjunction with the PFM-711A Field Meter.
    • Can be used with the PGB-745 Decay Electrodes or PRF-911 Concentric Ring
    Measure Material Decay Time
    Measure Decay Time of Ionizers
    The PDT-740B Static Decay Timer is typical of Prostat’s innovative technology and support of Professional ESD Control Managers and Auditors.

    This unique accessory is designed to measure the decay time of ionizers from ±1,000 volts to less than 100 volts in accordance with ESD Association’s Ionization Standard ANSI/ESD STM3.1, and measure material decay time to less than 50 volts and less than 10 volts.

    Evaluate Footwear, Grounding, Production Aids
    Evaluate Ionizers and Packaging Materials
    Properly used, the PDT-740B provides decay time measurements for evaluating ionizers, packaging materials, footwear, personnel grounding, production aids, some equipment and many other ESD control products.

    Compatible with our Field Meter and Charge Plate Monitor
    Use it with the PFK-100 Field Meter Set
    The PDT-740B Static Decay Timer is used with Prostat’s precision portable Charge Plate Monitor kit components, including the PFM-711A Field Meter, CPM-720A Charge Plate Assembly and PCS-730 ±1kV Charging Source.
    Measure materials by using the PRF-911
    Measure materials by using the PGB-745
    For evaluating materials and other products, additional decay measurement accessories e.g., PGB-745 Decay Electrodes, or PRF-911 Concentric Ring fixtures are recommended.
