Charge plate monitor extension set with ±1200 V HV converter for EFM 822/823

This charge plate set turns the EFM 822 or EFM 823 electrostatic field meter into a charge plate monitor for verifying air ionisers. The charge electrode meets the relevant standards with a capacitance of 20 pF.

The decay time from +1,000 V to +100 V or -1,000 V to -100 V is measured with the start-stop timer built into the EFM 822/823. Charging is performed via the included external ±1200 V HV converter. The field meter is not included in the set.

Key benefits

• Ioniser verification to EN 100015 and EOS/ESD S3.1
• Standard-compliant 20 pF charge electrode
• Compatible with both EFM 822 and EFM 823
