Ultrasonic Thickness Gauge Multigauge 5650 / 5750 Surveyor Gauge The Multigauge 5650 Surveyor / 5750 Surveyor Datalogger are simple, robust ultrasonic thickness gauges designed specifically for ship and small craft surveyors. The user has a choice of Multiple Echo, Echo to Echo or Single Echo to cover all requirements. The gauges can be used for metal, GRP or plastic measurement and they automatically switch modes and settings depending on the type of probe fitted. The easy to use keypad allows operator interface whilst the bright LCD display can be used in all light conditions. All probes have Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge at the same time as transmitting recognition data - the result is a perfectly matched probe and gauge for enhanced performance. Additionally, the Automatic Measurement Verification System (AMVS) used with multiple echo ensures only true measurements are displayed, even on the most heavily corroded metals. Features Ignores coatings up to 6 mm thick using Multiple Echo. Coating Plus+ ignores coatings up to 20 mm. Single crystal soft faced probes protected by a membrane and single crystal hard faced probes for linear accuracy. Automatic Measurement Verification System (AMVS) in multiple echo mode. Echo - Echo mode for enhanced performance. Inspect GRP for osmosis. Large colour LCD display giving user information. No zeroing required. Easy calibration with menu driven buttons.

About Multiple Echo All Ultrasonic Thickness Gauges should be calibrated to the velocity of sound of the material being measured. Coatings have a different velocity of sound than metal and it is important they are not included in the measurement. Multiple Echo ensures all coatings, up to 6mm thick, are completely eliminated from the measurement. How it works: A transmitted ultrasound pulse travels though both the coating and the metal and reflects from the back wall. The returned echo then reverberates within the metal, with only a small portion of the echo travelling back through the coating...
