N88-VI-M Pit Depth Gauge Metric Vessel Inspection Kit


Complete kit with 4 blade sizes to measure cracks, dents and corrosion depths. Comes with reversible 12/35 mm blade, 64 mm basic blade and 121 mm reach blade to span larger areas. Makes it possible to measure from spot corrosion depth to material loss, cracks and small dents in the material. Comes with analog metric dial.

Pit depth gauges are used to determine the amount of surface corrosion on metal constructions like pipelines, support structures, storage tanks, drill pipes or steel bridges But they can also be used on aircraft components or concrete structures. The measurements can be focused on local corrosion areas but with the proper extensions the corrosion inspector can span larger areas to determine the material loss and/or dents over these larger areas.

Our N88 range of pit depth gauges contains lever pit depth gauges used for basic measurement of pit depth, and continues with the Tri weld welding gauge a multi-purpose lever-style weld measurement gauge. It measures next to crack and pit depth 9 different welding parameters.

The range is followed by the dial gauges, digital and analog. Dial gauges are more accurate easy to use push to read gauges. We can supply a variety of kits to match your demand. The basic kits provide fast and acurate pit depth readings on small corrosion areas. The reaching pit gauges provide measurements on small dents and medium size corrosion areas. The bridging kits with longer extensions can span larger areas to measure material loss or dent depth over these larger areas The easy to use push to read dial indicators in the N88 series are completely interchangeable between all models of blades and bridges. Three different contact points can be supplied but any ADG contact point can be used however different lengths may effect the height zeroing.

Our Pit Gauges assure compliance with vessel, pipeline, tank and OCTG specifications for corrosion and erosion depth measurement.

Available Contact Points

  • 1

    Contact Point (or Standard) – N88-S. This Contact Point was designed for general Corrosion Testing, and remains the most universal in use. The #1 tapers down, over its length, to a blunt point that is less than 0.75mm (0.030”)  in Diameter.

  • 2

    Contact Point (or Conical) – N88-C. This Contact Point is more robust than the Standard Contact Point, due to its much larger size. The #2 Contact Point is recommended when a large amount of Scanning is being performed. The #2 tapers down, over its length, to a rounded point that is approximately 0.5mm (0.020”) in Diameter.

  • 3

    Needle Point – N88-N The Needle Point was developed to satisfy the needs of Corrosion Coupon Evaluations, where pits are shallow and small in diameter. The #3 Needle Point tapers down to a very sharp point, so as a result they tend to be very delicate.

Zeroing dial indicator before use

The vertical position of the Contact Point, needs to be Zeroed with respect to the Knife Edge of the Blade. Zeroing can be accomplished in two ways; by adjusting the Height of the Dial Indicator in the Blade; or by Rotating the outer Bezel Scale while pressing on the Plunger onto a flat surface.

Height Zeroing
Loosen the Fastener(s) holding the Dial Indicator in place. Hold the Blade firmly on a Flat Surface, and gently press the body of the Dial Indicator down until the contact point touches the flat surface. Carefully re-tighten the Clamp Fastener(s) or the Set Screw. Any fine zeroing can be done by rotating the Bezel Scale on the Dial Indicator

Dial Zeroing
To quickly check the Zero Point of the Dial indicator, place the Blade on a representative smooth surface. Gently press the Plunger, until the contact point touches the surface. While the contact point is on the surface, loosen the Bezel Lock, and rotate the Bezel Scale until it reads '0' with respect to the pointer.
