Model 900A ESD Event DETECTOr

Electrostatic discharge (ESD) events are important indicators of excessive charge accumulation in environments where electrostatic charging is detrimental to manufacturing processes in the semiconductor or LCD industries.

Trek’s Model 900A is a diagnostic tool used to identify incidents or verify suspected areas of ESD activity. An ESD sensitive antenna on the unit can be positioned in ESD sensitive environments to detect problem areas of electrostatic discharges.

Trek’s Model 900A ESD Event Detector alerts and displays information concerning electrostatic discharges. Upon an ESD event detection, an audible buzzer automatically sounds for two seconds (or it can be switched OFF) while five (5) color coded LEDs visually depict the relative intensity level of the event.

Resetting the unit is either performed automatically or manually by the use of a front panel selector switch. The unit can be powered 5 to 7 hours from batteries or a power cube can be used for continuous AC line operation.

Trek’s Model 900 ESD Event Detector is CE compliant.
