Full Kit Component List (Matched with the Provided Pictures)

1. EFM 023 Main Unit (Elektrofeldmeter)

   Core electrostatic field meter, with switchable 2cm / 10cm measuring distance modes, reading hold function and background field zeroing calibration. It performs non-contact measurement of electrostatic voltage and electric field intensity on material surfaces, PCBs and equipment.

2. CPS 022 HV-Converter High-Voltage Conversion Module

   Expands the original measuring range of the main tester, enables contact-type high electrostatic potential acquisition.

3. MK023 Measuring Probe Assembly

   Precision electrostatic induction probe for targeted and long-distance electrostatic signal detection.

4. CP RECYKO Calibration Zero Block

   Standard reference part for regular instrument self-check and zero-point correction to guarantee long-term measuring accuracy.

5. EU-spec Power Adapter

   Power supply and battery charging accessory for the main device.

6. Two sets of test leads

• Coiled black cable with alligator clip: For grounding reference measurement
• Red-yellow multimeter test leads: For direct contact voltage testing

7. Standard metal test plates, custom fitted aluminum carrying case, factory original calibration certificate

   Each unit comes with a traceable German factory calibration document, which is acceptable for ISO & ESD S20.20 third-party audit and quality system review.

Primary Industrial Applications

1. Human Body Walking Electrostatic Potential Test

   The most typical application, fully compliant with ANSI/ESD S20.20 and IEC 61340 international standards. It verifies electrostatic buildup generated by operators while walking on anti-static flooring with ESD garments and footwear, to confirm proper grounding and personal anti-static protection.

2. Non-contact electrostatic inspection on PCB assemblies, packaging trays, ESD containers and workbench surfaces.
3. Ionizer balance & offset performance verification, auxiliary testing of anti-static tabletop and floor resistance, and electrostatic risk troubleshooting for sensitive electronic components.
4. Widely deployed in SMT factories, semiconductor fabs, optical cleanrooms, medical device manufacturing and other ESD-controlled production environments

   Differences Between the Three Model Versions

   Model	Core Feature Difference	Typical Application
   EFM022-AKC	Entry-level basic version with standard measuring range	Routine single-point electrostatic spot checks
   EFM023-AKC	Standard full accessory package (the kit pictured), complete with all parts for human body walking ESD testing	On-site factory audit, daily workshop ESD patrol (most widely purchased configuration)
   EFM025-AKC	High-precision upgraded variant with improved resolution and extended measurement range	Laboratory metrology and third-party professional inspection institutions

   Procurement & Maintenance Notes

   1. Authorized import distributors supply brand-new original units complete with customs clearance documents and factory calibration certification within mainland China.
   2. As a precision metrology instrument, annual recalibration by the manufacturer or accredited third-party labs is recommended to maintain measurement validity.
   3. The main meter can be purchased separately; the suffix -AKC denotes the full audit kit configuration for official compliance inspections.
