DeltaFlux DF S LZ 642 Digital AC/DC Gaussmeter

The DeltaFlux DF S LZ 642 is a portable AC and DC gaussmeter from the LZ series. With 0.1 G resolution and N/S polarity it measures residual magnetism in machined parts, the field left after demagnetisation and the surface field of permanent magnets. Its AC function also maps alternating field distribution.

Key features

• Polarity: N/S indication on DC fields
• Units: G, T, Oe, A/m
• Independently calibrated probes: transverse and axial probes with their own calibration codes; automatic zero
• Field use: 4 × AA batteries, over 30 hours with backlight off
