Digital-Charged-Plate-Monitor-Model-280A

Simco-Ion Digital Charged Plate Monitor Model 280A

Simco-Ion’s Model 280A 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 opened 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.
