Warmbier EFM51 Plus Electrostatic Field Meter, Pocket-Size
The EFM51 Plus is a full-featured hand-held field meter used to perform static surveys and evaluate charge accumulation in electronic manufacturing and industrial operations. The EFM51 Plus measures static voltages within 20kV (20,000V) with a microcontroller that calculates the field strength (V/m) at a pre-selected distance (1cm, 5cm, 10cm, and 20cm). Results are displayed via a 12-digit alphanumeric LCD screen. Two LED guide ring lights help position the field meter at the proper distance from a charged test object. The EFM51 may supplement the Ionizer Performance Analyzer EFM51 Plus. CPS "Charge Plate Set" can also be used to check and verify ionizer efficiency and offset voltage. The kit measures static decay times from +/-1.000volts to +/-100volts. The EFM51 meets periodic test requirements per Compliance Verification ESD TR53 and conforms to ANSI/EOS/ESD (S4.1, S7.1, S12.1, S2.1).
