Portagauge® 6
Multi‑echo Ultrasonic Thickness Gauge
The Portagauge® 6 is a multi‑echo ultrasonic instrument designed to measure the wall thickness of metals and rigid plastics. It is capable of taking accurate readings through surface coatings of up to 20 mm without removing them. The unit features an integrated data logging system with capacity for up to 200,000 measurements, along with an alarm function to alert users when minimum thickness limits are reached.

CAGE Code: KD983 – Coltraco Limited
Multi‑Echo Technology Meeting Classification Society Standards
The advanced multi‑echo ultrasonic method complies with Classification Society requirements and automatically excludes paint and coating layers up to 20 mm thick. This ensures that only the actual metal thickness is measured, with precision to ±0.1 mm.
Ideal Tool for Wall Thickness Inspection
The Portagauge® 6 is a precise and dependable multi‑echo ultrasonic thickness gauge suitable for a wide range of metals and rigid plastics. It has been developed in accordance with BS EN 15317:2013, the international standard governing ultrasonic thickness measurement equipment, including testing, characterisation, and verification.
Key Features
Integrated material library with sound velocity data for more than 14 materials, plus the ability to define custom materials
Measurement units selectable in metric (millimetres) or imperial (inches)
A‑scan and oscilloscope display modes to support accurate interpretation of readings
On‑device data logging for instant storage of measurements at the press of a button
Suitable for marine environments, meeting Classification Society requirements and equipped with a backlit LCD for low‑light conditions
Up to 12 hours of continuous operation using a standard 9V PP3 battery, with an automatic power‑saving function after 30 seconds of inactivity
USB power capability, allowing the unit to operate directly from an external power source to conserve battery life and enable extended or continuous useisibility in any environment
Overview
Multi‑Echo Measurement with Coating Compensation
Measure material thickness quickly and accurately without stripping paint or surface coatings. The instrument is designed to disregard coatings up to 20 mm thick, delivering true base‑material thickness readings with an accuracy of ±0.1 mm.
The Portagauge® 6 ultrasonic thickness gauge operates effectively through protective layers, enabling reliable assessment of corrosion or erosion while avoiding surface damage that could accelerate deterioration.
