Audit 207
The Audit 207 is an ultrasonic thickness gauge for measuring wall thickness on pipelines and pressure vessels, supplied in Malaysia by Asia NDE.
Rugged one-handed ultrasonic thickness gauge for pipelines and pressure vessels, measuring 0.63–500mm with a scan mode that shows live and minimum readings.

Overview
Key advantages
- Precise thickness measurements with excellent stability.
- Ergonomically designed for easy one-handed operation.
- Rugged extruded aluminium body with gasket-sealed end caps.
- Scan mode shows the live reading and the minimum found so far.
Overview
The Audit 207 is built for site work in oil and gas, petrochemical and power plants. It measures wall thickness on pipelines, pressure vessels and storage tanks. In scan mode it displays the current thickness “live” while simultaneously showing the thinnest measurement found – without lifting the probe.
