Multigauge 3100 Surface Display Unit

The Surface Display Unit is used with the Multigauge 3000 Underwater Thickness Tester to verify the measurements that the diver is getting, by either a class surveyor or supervisor. Also, readings can be clearly taken on the surface if the diver is operating in zero visibility.

The Surface Display Unit has bi-directional communication with the Multigauge 3000 Underwater Thickness Tester – This means that settings can be adjusted in the Multigauge 3000 without having to break the ‘O’ ring seals. Also, settings can be adjusted whilst the diver is underwater using the Multigauge 3000 Underwater Thickness Tester.
