Portagauge® 4 Triple Echo Ultrasonic Thickness Gauge allows measurements of the metal independent of any surface coatings such as paint. Submit an enquiry and our expert team will send you details and pricing within 24 hours.

Accurate: To +/- 0.1mm

Capability: It can measure thicknesses up to 250mm and the resolution can be set to either 0.1mm or 0.05mm depending on requirement.

Technology: The Triple Echo Ultrasonic Thickness Gauge sends multiple signals into the metal. By measuring the different reflections, the Portagauge 4 can isolate the pure metal readings, ignoring any surface coatings like paint

Ergonomic: With comfortable rubberized enclosure and the option of a plastic case to protect the unit from dirt, the Portagauge 4 is among the most ergonomic models of the range.

Versatile: With multiple sensor options available

  • 2.25MHz probe – measuring range of 3 to 250mm (included as standard)
  • 2.5MHz probe – measuring range of 2 to 150mm
  • 5MHz probe – measuring range of 1 to 50mm

Five Core Benefits:

1. Quick testing allows the user to test a large range of metals within a short period of time. Intelligent Probe Recognition (IPR automatically adjusts settings at the same time as transmitting recognition data.

2. Ideal for a wide range of industrial applications: fire cylinders, ship hulls, pipework, storage tanks. Ability to work on heavily corroded metal.

3. Triple Echo technology gives true metal thickness ie excluding coating and paint thickness.

4. Highly accurate units – measurements in steps of 0.1mm from 1.5mm – 99.9mm.

5. Portable unit, lightweight, compact and with long-term reliability.
