Ion's next-generation Charge Plate Monitor (CPM) Model 280 is an easy-to-use, self-contained instrument for precise testing of ionizer performance. The Model 280 ensures a consistent discharge time measurement for all plate sizes. All measurement parameters are progrrammable and the CPM is capable of 6 hours of operation on the internal battery before recharge. The Model 280 ough memory for storage of over 1000 tests and more than 100 individual test locations.
