The Monroeᵀᴹ 288C is an easy-to-use, charge plate monitor for manual or automated testing. All test parameters are programmable, allowing tests to be optimized and not dictated by equipment limitations. Once programmed, the Monroeᵀᴹ 288C will perform a series of tests automatically: ± decays, balance, balance peaks, temperature, humidity, time/date are stored and may be reviewed via the display or downloaded to a PC. The included software permits the user to define and name ionizer locations, test setups, and sequences and upload them to the CPM. All of these features result in a flexible, easy-to-use instrument that facilitates audits while minimizing errors.
