DeltaFlux DF S 203 / 204 / 205 / 206 Pocket Magnetometer (Residual Magnetism)

The DeltaFlux DF S 203–206 pocket magnetometers are handy analogue instruments that show residual magnetism in steel parts in seconds. Hold the lower (test) edge near the part and the pointer deflects in proportion to the magnetism at that point. The centre-zero scale also shows polarity: a (+) deflection means the test edge faces a North pole.

Key features

• Four ranges: DF S 203 ±5 G, DF S 204 ±10 G, DF S 205 ±20 G, DF S 206 ±50 G
• Demagnetisation check: quickly confirms parts are demagnetised to safe levels
• Two-colour scale: black scale reads gauss in a uniform field; red scale gives magnitude and direction of an unknown field
• Practical: fast, easy and economical for tool rooms, stores, inspection and production
• Temperature correction: percentage correction from a straight-line graph at extreme temperatures

Technical specifications

• Models: DF S 203 (±5 G), DF S 204 (±10 G), DF S 205 (±20 G), DF S 206 (±50 G)
• Type: Analogue, centre zero, two-colour scale
• Measures: Residual magnetism and polarity
• Calibration: At room temperature; correction graph for extremes
• Caution: Do not expose to fields above 400 gauss and do not drop

Applications

• Demagnetisation check after MT
• Residual magnetism before grinding, welding or plating
• Reducing magnetic dirt on bearings, shafts and precision parts
• Incoming and outgoing inspection
