Sonatest Alphagage+

As a leading solution for corrosion assessments and precise thickness measurements, the Sonatest AlphaGage+ instrument employs advanced technologies tailored to different industry needs.

Overview

AlphaGage+ Corrosion (C )

Uses dual element transducers to measure remaining wall thickness on primarily steel structures subject to corrosion.

• Compatible with a wide variety of dual element and a limited number of single element transducers
• Wide thickness range (.020” to 23” depending on gage type, material and transducer)
• Echo-to-echo readings to ignore coatings
• High temperature probes available up to 950F/509C (intermittent use)
• Temperature correction
• Gridview
• Password lock
• Supervisor and other locks
• 2,700 stored setups
• Change color and vibrate on alarm
•  

AlphaGage+ Precision (P)

Allows for the use of single element transducers along with up to 2,700 stored application setups with 1 micron resolution.

• 0.006-23” range in steel
• 1 micron resolution (0.0001” or 0.001 mm) 
• Single element, contact, delay line and immersion transducers (1-30 MHz) 
• Supervisor and other locks    
• 30 Mhz bandwidth 
• Zoom Auto Tracking
• Multiple modes for challenging applications 
• Square wave Pulser
• Auto Phase Reversal Detection with alarm

Data Logger (DL) Upgrade

Datalogger software with B-Scan. Internally store millions of thickness readings with ID location and send readings to Microsoft Excel via Data XL interface program. File compare features shows old readings along with new readings for real-time corrosion monitoring.

Waveform (W) Upgrade

Live Waveform A-Scan. Displays the live A-scan for echo verification and real time control of range, gain, rectification and blanks. Coating thickness and substrate thickness displayed simultaneously.

Oxide Scale (OS) Upgrade 

Oxide Scale (Boiler Tube). Simultaneously displays the wall thickness of the boiler tube thickness as well as the internal oxide scale at their independent velocities. Only available on PW options.
