Charged plate monitor CPM74 絕緣測試儀是德國Wolfgang Warmbier GmbH & Co. KG Systeme gegen Elektrostatik的一款產品。

• Measures the air ionizer efficiency and the offset voltage
• Measures the electrostatic decay time from ± 1000 V to ± 100 V (standard setting)
• Measures the (150 x 150 mm) plate potential with a built-in electrostatic field meter
• Records the measured values in memory
• Plate can be removed in order to apply the high voltage head to the field meter
• High voltage head allows direct voltage measurement of up to 2 kV
• Size: 15,2 x 15,2 x 15,2 cm (W x H x D)
• Complies with IEC 61340-4-7

• power supply 230 VAC
• ground cord
