Multigauge 5750 Surveyor Datalogger

The Multigauge 5750 Surveyor Thickness Meter is a simple, robust ultrasonic thickness gauge designed specifically for ship and small craft surveyors, but can also be used in applications where different measurement modes are required. The user has a choice of Multiple Echo, Echo to Echo or Single Echo to cover all requirements. The gauge can be used for metal, GRP or plastic measurement and it automatically switches modes and settings depending on the type of probe fitted. It has the added benefit of being able store measurements on the gauge and remotely displaying measurements on a PC. 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.

Measurements can be logged using a grid or string format. The gauge will store up to 895 files, each containing 100 records. Each record can store either a string of 250 or grid of 16 x 16 measurements. The simple, easy to use menu guides the user through intuitive setup procedures.

The Surveyor thickness meter uses wireless technology to transmit the measurements to the PC where dedicated Communicator software allows the analysis of the results or easy production of templates using wizards. Measurements are stored in a .txt format so that they can be opened in other applications.

Measurements can also be displayed remotely on a PC up to 1000 meters away.
