Profile: Monroe Electronics, Inc. is a manufacturer of electrostatic measurement and ESD products. Our product line includes electrostatic voltmeters, fieldmeters, charge plate monitors and resistant meters. Our ISOPROBE® electrostatic voltmeter measures surface potential in the range of ±3000 volts without contacting the measured surface. The volmeter is featured with high-accuracy (0.1%), drift-free measurements that are almost fully independent of probe-to-surface separation. Our model 288B is the first charged-plate monitor offering on-board data storage to automate ionization system testing. Our system is equipped with all types of ionizers, automated testing reduces ionizer test time & data logging time and small ion collecting plates are available to permit measurements in confined spaces.
