The Charge Plate System, model 282CPS is an accessory for the model 282 Fieldmeter that permits the model 282 to measure ionizer performance. The 282CPS includes a charge plate attachment for the fieldmeter and a charging source to charge the plate attachment. The fieldmeter then measures the plate voltage during balance and decay tests.

• Lowest-cost test method for periodic verification of ionizers

• Correlates closely to charged-plate monitor test results

• Performs both positive and negative decay tests

• Also works with Model 281
