Field meter verification kit in aluminium case - Safeguard SFM PRO AKC

The Safeguard SFM PRO AKC brings the full range of precise ESD measurement systems together in a sturdy aluminium case with foam insert. The set combines the Safeguard field meter, the charge plate set (CPS) and a volt meter set (VMS) for the walking test, covering field measurement, ioniser verification and body voltage measurement.

The field meter works on the field mill principle: a star-shaped induction electrode interacts with a grounded rotating modulation impeller, and a ring electrode system protects the impeller and field plate. With the charge plate set it becomes a charge plate monitor for ionisation equipment; the decay time from +1,000 V to +100 V (or -1,000 V to -100 V) is timed by the built-in start-stop timer, with charging supplied by an external HV converter. The volt meter set extends the system into a walking test kit with voltage probe, hand electrode and accessories.

Key benefits

• Three measurement tasks in one case: field measurement, charge plate monitoring and walking test.
• Ioniser verification to IEC 61340-5-1 and EOS/ESD S3.1 via the CPS.
• Walking test for body voltage measurement and ESD control checks.
• Very high zero-point stability: no adjustment needed before each measurement.
• One-button operation with battery voltage monitoring and auto power-off.
