Multigauge 4000 ROV

The Tritex Multigauge 4100 and 4400 Underwater Thickness Gauges are simple, robust ultrasonic thickness gauges designed to be mounted onto all types of work class ROV’s. There are two models in the range, the Multigauge 4100 which has a depth rating of 1000m and the Titanium Multigauge 4400 which has a depth rating of 4000m.  Both gauges have been designed and built to survive extremely harsh conditions that exist in the offshore and underwater industries worldwide.  The gauges use multiple echo which means measurements can be easily taken without the need to remove coatings, up to 6mm thick, and the user selectable RS422 / RS232 output makes connection to most ROV’s simple.

The gauge is equipped with IPR (Intelligent Probe Recognition), which automatically adjusts settings in the gauge for enhanced performance and AMVS (Automatic Measurement Verification System) to ensure only true measurements are displayed, even on the most heavily corroded metals.
