⚠ This Product Has Been Discontinued
The Warmbier CPM74 Charge Plate Monitor (7100.CPM74) is no longer available. It has been replaced by the newer Warmbier CPM54 Charge Plate Monitor, which offers improved features including a color display, selectable start/stop voltages, body voltage measurement up to 2000V, and full ANSI ESD2020 compliance.
Warmbier CPM74 Charge Plate Monitor (Discontinued)
The Warmbier CPM74 was a simple-to-use portable device for measuring ESD air ionizer performance. It tested ionizer decay times and offset voltage (balance) per ANSI ESD2020 and IEC 61340-2-1.
Original CPM74 Features (For Reference)
- ESD Compliance: Quickly test ionizer decay times and offset voltage per ANSI ESD2020 and IEC 61340-2-1
- Simple Operation: Easy 2-button control
- Compact & Portable: Internal rechargeable battery, easy-to-carry design
- Voltmeter Mode: Optional high-voltage head allows direct voltage measurement up to 2kV (sold separately, p/n: 7100.CPM74.HM)
- Analog Output: +/- 1V
- Operating Time: ~6 hours on battery
Upgrade to the Warmbier CPM54
The CPM54 (7100.CPM54) is the recommended replacement and delivers significant improvements:
- Full-color display showing all parameters and results
- Fully automatic positive and negative decay time testing plus offset voltage
- Selectable start voltages: 1000V, 500V, or 250V
- Selectable stop voltages: 100V, 50V, or 35V
- Body voltage measurement up to 2000V (Walking Test per IEC 61340-4-5)
- Analog output: +/- 5V via BNC
- 1/4" tripod socket for hands-free positioning
