Simco-Ion’s Model 280A Charged Plate Monitor (CPM) incorporates enhanced circuitry that enables it to more accurately measure the performance of high-frequency AC ionizers, as well as pulsed DC ionizers and steady-state DC ionizers. The Model 280A, built on the Model 280 platform, incorporates enhanced circuitry that enables it to more accurately measure the performance of high-frequency AC ionizers. The architecture of the Model 280A simplifies testing in open or enclosed environments. The detachable plate and programmable automated test sequencing offer remote testing capability, allowing multiple tests without opening an enclosure to reset the instrument.

The Model 280A can be used as a portable CPM and is capable for of up to 6 hours of operation on the internal battery before recharge. It has enough memory for storage of over 1000 tests and more than 100 individual test locations.
