Ultrasonic Thickness Gauges for Corrosion & NDT Inspection
PTX Industrial supplies professional ultrasonic thickness gauges for non-destructive measurement of metal thickness, wall loss and corrosion. Our ultrasonic thickness gauges are suitable for pipes, tanks, pressure vessels, steel structures, boilers, marine vessels, mining equipment and industrial maintenance applications.
Choose from standard ultrasonic thickness gauges, through-coating models, high-temperature gauges, thin-material gauges and advanced A-Scan and B-Scan instruments. Measurement ranges are available from approximately 0.15 mm up to 508 mm depending on the model and transducer.
PTX Industrial provides local Australian technical support, optional traceable calibration and a range of ultrasonic probes, couplants and calibration blocks. Whether you require a simple thickness meter for routine inspection or an advanced ultrasonic thickness gauge for corrosion monitoring and asset integrity applications, our team can help select the appropriate instrument.
