The Portagauge 3® was designed to be as simple and durable as possible. With only 2 controls (on & off) the device offers an effortless, plug and play method for quickly inspecting large metal surfaces. Of all the units manufactured by Coltraco, this is undoubtedly the easiest to operate! Accurate to 0.1mm, the unit is primarily used for corrosion and condition inspections. The device can very quickly help the user find internal corrosion in structures and because it is so quick to operate, large surface areas can be quickly inspected. This is especially valuable when inspecting pipework, hulls, process machinery and other applications with particularly long metal structures.

With a hard aluminum case and significant internal electronic protection, the Portagauge 3 can survive very rough handling. A variety of different sensor options are also available, including:

  • 6mm Thin Material probe – measuring range of 0.1mm to 50mm and ideal for thin diameter applications such as small pipework
  • 10mm Standard Probe – measuring range of 1.5mm – 99.9mm and ideal for the vast majority of measurement applications
  • 12mm High Temperature probe – 4mm to 99.9mm and capable of operating on metal surfaces up to 70C / 160F
