ESD constant monitoring ensures that grounding systems at an ESD workstation are continuously verified rather than checked only once or twice per day with manual tests. The CM1800GZ and CM1600GZ are resistance-based ESD constant monitors that continuously confirm operator and workstation grounding integrity. The CM1800GZ provides advanced monitoring with integrated data logging for compliance tracking and audit support, while the CM1600GZ offers the same high-accuracy monitoring without data logging. Their resistance-based technology delivers far greater accuracy and reliability than capacitance-based ESD monitoring systems.
