Ultrasonic
Audit 9000
The Audit 9000 is an ultrasonic corrosion thickness gauge and is available in four models to suit budget and application.
Advantages of the Audit 9000 include:
- Field upgradeable software options including live waveform, datalogger or both
- Coating Thickness Software option
- Vibrate Alarm
- Encoder option
- Accessory Mount

Overview
The Audit 9000 represents our most advanced thickness gauge ever, offering a 3.5”, high resolution, sunlight readable colour display with live A-Scan, echo to echo to ignore coatings. A wide variety of contact, delay line and immersion probes, are available, from 1-20 MHz as default, with the capability of creating custom and stored application setups. B-Scan and Datalogger functions are optional, with up to 32GB of SD card memory and can be interfaced to Microsoft Excel. The vibrate on alarm feature is a great feature for when working in noisy environments.
