The EFM51WT Walking Test Kit is a hand-held  meter used to test the performance of ESD floors in combination with a person per ANSI/ESD STM 97.2. and IEC Standard 61340-4-5.


The EFM51WT meter is also  a fully functioning field meter used to measure and detect electrostatic fields, surface potentials and discharge times (with optional charge plate accessory.)  The charge plate accessory along with the meter can test and verify ionizers.


The EFM51.CPS is a full-featured hand-held field meter used to evaluate ESD ionizers efficiency as well as perform static surveys and evaluate charge accumulation in electronic manufacturing and in industrial operations. The meter measures the decay time from +1.000V to +100V or -1.000V to -100V with its integrated start-stop timer. The plate is charged manually via the handheld high voltage generator.


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).
