Charged plate monitor analog - Warmbier CPM 74

The Warmbier CPM 74 is an analogue charged plate monitor for measuring the effectiveness of ionisers and their offset voltages. Using an integrated plate electrode (150 x 150 mm) and a built-in field meter, the device determines the decay time from a preset voltage threshold to a lower value (default +/- 1000 V to +/- 100 V), giving the compliant figure for assessing ionisers to IEC 61340-4-7.

Key benefits

• Direct assessment of ionisers via decay time and offset voltage in one device.
• Integrated 150 x 150 mm plate electrode with built-in field meter for reproducible measurements.
• Freely selectable voltage threshold, default +/- 1000 V to +/- 100 V.
• Measurement data stored directly in the CPM for later evaluation.
• Removable plate electrode to adapt the high-voltage sensor head for direct measurements up to 2 kV.
• Compact cube form (152 x 152 x 152 mm) for flexible placement.
