KLEINWACHTER EFM022VMS Human Body Static Potential Tester, Human Walking Static Potential Tester


The EFM022/023 tester combined with the VMS023 static potential test kit forms the human walking static potential tester. It can measure human walking static potential according to EN61340-4-1 and EOS/ESD S.3.1.

Features and Advantages

* EFM-022 range 0V~+/-200kV, capable of accurately measuring the surface static electricity of charged objects at different distances.
* Accuracy +/-5%.
* Globally high resolution, display value 1V.
* Dual-line digital and alphabetic display.
* Easy to operate, no need to zero before measurement.
* HOLD value lock.
* VMS mode can detect human body static potential.



Applications and Principles


The EFM 022 is a portable and easy-to-use electrostatic field tester. Compact in size, single-button operation, with an electrostatic dissipation material casing that effectively shields signal interference.
Paired with the CPS022 high-voltage generator, it can test and record the ion dissipation time and ion balance of ion fans.
