    SKU TT-EFM51


    Satisfaction Guarantee

    The Wolfgang Warmbier EFM51 is a handheld meter to quickly detect and measure electrostatic charge accumulation on surfaces.

    The EFM51 is a full-featured hand-held field meter used to perform static surveys and evaluate charge accumulation in electronic manufacturing and in industrial operations. The EFM51 measures static voltages within ±20kV (20,000V) with a microcontroller that calculates the field strength (V/m) with 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 right distance from a charged test object.

    Ionizer Performance Analyzer
    EFM51 may be supplemented by the EFM51.CPS “Charge Plate Set” and 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).
