DA-400 Series Contour Probes®
The DA-400 Contour Probe is a portable, self-contained instrument designed to produce a magnetic field on or within ferro-magnetic materials.
The selective ACpulsed DC functions are built into a single reliable instrument. The AC mode produces an intense AC field for detection of surface defectsdemagnetizing after inspection. The DC mode produces an intense pulsed DC field for detection of some subsurface defects.
Controlssolid-state electronics are contained within the high impact molded housing. Articulating legs allow the AC or DC field to be applied to the precise area of inspection on nearly any part of the surface shape... in the lab, factory or field site.
All Parker Contour Probes comply with the requirements of applicable specifications. Certified for European CE requirements.
- Versatilitypowerful performance in a lightweight (8 lbs.) instrument
- Constant AC or pulsed DC fields with the flip of a switch for the location of surfacesome sub-surface defects
- Apply continuous or residual magnetic fieldsdemagnetize too
- Use with dry powder, wet fluorescent or visible
- High impact molded housing
- One year repair/replacement guarantee
