Each Charge Plate Monitor Offers High Accuracy and Flexibility in Plate Size and Capacitance, Ideal for ESD Applications

Trek Charge-Plate Monitors employ a revolutionary charge plate monitor design that utilizes an ultrahigh-impedance, high-voltage follower to monitor the ion collecting plate voltage. This technique provides very high accuracy and virtually infinite impedance loading of the plate, while allowing the ion collecting plate to be charged and monitored through the same small-diameter connection. This technique also makes the measurement capacitance independent of the physical size and shape of the ion plate. Therefore, the size and shape of an ion collecting plate, as well as the measurement capacitance, may be customer specified to match a particular ESD-sensitive device within a manufacturing process. Charge Plate Monitors can be used for ionizer testing, ionizer maintenance and other ESD applications.

Model 159HH Hand-Held Charge Plate Monitor

This small, lightweight, easy-to-use hand-held charge plate monitor offers highly accurate measurements within a compact design. It is used to evaluate ionizer performance for parameters such as ion balance, decay performance, rate of charge decay, and other decay characteristics. Data is stored on the internal memory but is accessible via USB port.
