Underwater Ultrasonic Thickness Gauge Multigauge 3000
Underwater Ultrasonic Thickness Gauge with multiple echo / 10 mm LED display / 
for extreme conditions under water / can be used in up to 500m deep water / 
IPR and AMVs / battery life up to 55 hours

The Multigauge 3000 is an easy-to-use but very sturdy underwater ultrasonic thickness gauge. The underwater ultrasonic thickness gauge has been specifically designed for thickness measurements below the water surface and under extreme environmental conditions. Therefore the underwater ultrasonic thickness gauge can be used worldwide to peform ultrasound thickness measurements in up to 500 m deep water. The underwater ultrasonic thickness gauge Multigauge 3000 also owns a large, bright LED display with a good readability, this allows the diver to read the test results even in poor visibility conditions. Thanks to the multiple echo, the ultrasonic thickness gauge allows fast accurate measurements without having to remove layers before. Furthermore, the underwater ultrasonic thickness gauge is equipped with IPR (Intelligent Probe Recognition) and AMVs (Automatic Measurement Verification System). IPR automatically increases the performance in the underwater ultrasonic thickness gauge,  AMVs guarantees that only meaningful measurement results are displayed, even on badly corroded metals. The integrated battery of the underwater ultrasonic thickness gauge has a duration of up to 55 hours. Another advantage of the battery is the low load time. Here you will find an overview of all underwater ultrasonic thickness gauge (s)..

More information on the threefold echo-technology

Depending on the material to be measured, each multiple echo thickness gauge should be calibrated at different sound velocities. Paints have different sound speeds as metals, it is necessary to ensure that these do not affect the measurements. The 3-echo technology guarantees that all coatings have no effect on the measurement.

This is how the measurement of the underwater ultrasonic thickness gauge works

A transmitted ultrasonic pulse is sent through paint and metal and is reflected by the rear wall. The returning echo reverberates in the metal and only a small part of the echo returns through the coating. The time between the small echoes gives us the time of the echo within the metal, this time is in direct connection to the material thickness. The multiple echo thickness gauge interprets the recurring echoes automatically and calculates the thickness of the material. A minimum of three echoes is checked each time. This is called Automatic Measurement Verification System (AMVs).

Standard units of the underwater ultrasonic thickness gauge Multigauge 3000

The standard unit makes it possible for the diver to carry out underwater measurements. The large, bright display allows good readability even in poor visibility conditions. The underwater ultrasonic thickness gauge benefited from the fact that it is very accessible and easy to hold.

Optional accessories for the underwater ultrasonic thickness gauge Multigauge 3000

Pulse stretching
The underwater ultrasonic thickness gauge can be fitted with a pulse stretching, by simply replacing the end head. This extension cable can be up to 1000 m long.

Surface display unit
The surface display unit of the underwater ultrasonic thickness gauge shows the measurement results of the Multigauge 3000 diving unit. This makes it possible to show the readings above the surface of the water, for example if there is a bad visibility under water or if the measurement results must be verified by a second person. Additionally allows the surface display unit to change the settings of the diving unit, for example calibration, measurement units and resolution. 

Software
The software of the underwater ultrasonic thickness gauge shows the measurement results on a laptop, this option allows you to safe the data as required. The kit contains a RS232 - USB conversion cable to connect the ultrasonic thickness gauge with a laptop. Furthermore, the software makes it possible to change the settings, display measurement and save the results of the underwater ultrasonic thickness gauge by a bidirectional connection
