Model 158 includes color graphics display to permit viewing of discharge waveforms and offset voltage in time domain. It stores test data and waveforms from hundreds of ionizer tests on removable PCMCIA flash memory card. Unit is line or battery operated. Over-the-shoulder portability allows operator to move about facility unencumbered. Model 158 resolves 0.1 V plate voltage.



Original Press Release:


The New TREK Model 158 Charged-Plate Monitor Provides Dependable and Portable Ionization Monitoring


The TREK Model 158 Charged-Plate Monitor is the premier instrument to evaluate the performance of air ionization systems.

Unique among charged-plate monitors, the Model 158 features a color graphics display to permit viewing of discharge waveforms and offset voltage in the time domain, and the ability to store test data and waveforms from hundreds of ionizer tests.

The compactness and over-the-shoulder portability of the Model 158 permits the operator to move freely about the facility to evaluate ionizers, unencumbered by the need for auxiliary equipment such as computer or other collateral materials normally
needed to record test results.

The Model 158 is line or battery operated and is shipped with two battery packs. The battery pack is easily removed and replaced with a fresh pack to permit operation on the factory floor for extended periods of time.

Test data is stored on a removable PCMCIA flash memory card. The card containing test results is easily removed from the cleanroom facilities to office areas where the test results can be downloaded, evaluated and transferred to reports.

For those demanding very strict ion balance, the Model 158 resolves 0.1 V plate voltage.

The Model 158 uses the patented TREK voltage-follower technique to provide accuracy, stability, and bandwidth that is unavailable from charged-plate monitors which employ fieldmeter-based measurement methods.

Trek's voltage-follower technique provides virtually immeasurable loading effect of the ion collecting plate, while allowing the plate to be charged and monitored through the same, small diameter cable. The size and shape of the ion collecting plate and the plate's capacitance to ground may be optionally tailored to a particular application.
