Charged plate monitor, CPM35

The CPM35 is a handheld, fully automatic instrument designed for testing and verifying ionizers in ESD-protected areas. It quickly measures positive and negative decay times as well as offset voltages to ensure ionizers comply with international ESD standards. The device also supports Walking Tests, allowing easy evaluation of body charge generated during movement. CPM35 includes two modes: Decay mode, measuring discharge time from ±250 V to ±100 V while checking that offset remains below 35 V, and Offset/BVT mode, which displays maximum offset values and enables simple body voltage testing through a touch electrode. Its portable design makes the CPM35 ideal for both production use and field inspections.
