Magnaflux QB2-Plus Quick Break Tester and Shot Timer (AC / HWDC / FWDC / 3-phase / MD)

The QB2-Plus provides a quantitative verification of Quick Break function and measures the duration of the magnetizing shot. The QB2-Plus can verify the correct function of AC, HWDC, and FWDC equipment, and verify Quick Break function on 3-phase FWDC units. Shot time and Quick Break voltage are alternately shown on the LCD display after each reading.

Note: QB1 Part Number: 625972 and QB-2 Part Number: 622646 have been discontinued and replaced by QB-2 Plus

The QB-2 probe is placed inside the coil (or in line with a cable wrap) during a magnetizing shot, quick break voltage and shot time seconds are alternately shown on the LCD display. A reference table of minimum quick break voltages for different coil diameters is included on the back of the meter.

Using the QB-2 to check your 3-phase FWDC magnetic particle inspection equipment will help ensure residual field is properly developed during processing and gives sharper resolution of transverse indications. For use with 3-phase full-wave DC equipment only.
