Multigauge 3100 Surface Display Unit for Multigauge 3000 Underwater Thickness Measurement Verification

Multigauge 3100 is a Surface Display Unit for use with the Multigauge 3000 underwater thickness tester. It duplicates diver readings so a class surveyor or supervisor can verify measurements from the surface, including when underwater visibility is zero.

Bi-directional communication allows settings in the underwater Multigauge 3000 to be changed from the surface without breaking O-ring seals. The connected underwater tester can also be calibrated remotely through the surface unit during diver operations.

A multi-character LCD with white backlight presents readings and user information. The unit displays remaining battery life for both itself and the connected Multigauge 3000, supporting topside monitoring of the measurement system.

The surface unit uses three disposable AA alkaline batteries or rechargeable NiMH or NiCd cells. Stated alkaline battery life reaches 50 hours. It is normally supplied with a 100 m umbilical reel, with other lengths available.

The topside repeater can be added to an existing Multigauge 3000, and the kit fits its Peli case. Confirm underwater-gauge compatibility, end cap, umbilical length, connectors, power, supplied accessories, and calibration arrangement before ordering.

FAQs

• What does the Multigauge 3100 display? It duplicates measurements from the connected Multigauge 3000 and shows battery information for both the underwater and surface units.
• Can settings be changed from the surface? Yes. Bi-directional communication enables remote setting changes in the Multigauge 3000 while the diver remains underwater before procurement and use.
• Can the underwater gauge be calibrated topside? Yes. The product states that the connected Multigauge 3000 can be calibrated from the surface display unit before procurement and use.
• What umbilical length is normally supplied? The unit is normally stated with 100 metres of umbilical on a reel, while other lengths are available.
• Which batteries does the surface unit use? It uses three AA alkaline batteries or rechargeable NiMH or NiCd cells according to the listed specifications before procurement and use.
• What battery life is stated? The Surface Display Unit provides up to 50 hours of continuous use when fitted with alkaline batteries before procurement and use.
• Can it retrofit an existing Multigauge 3000? The topside repeater can be added to an existing Multigauge 3000; confirm the end cap and connection requirements.
