Elcometer MTG6 Ultrasonic Material Thickness Gauge

As well as all the features of the MTG4, the Elcometer MTG6 Ultrasonic Material Thickness Gauge has additional calibration options; 2-Point, Velocity and Thickness Set.

The MTG6 offers Velocity Mode (VM) which is ideal for determining the homogeneity of a material/alloy and the correct velocity of a material for calibration.

Using Scan Mode, readings can be taken at a rate of 16Hz (16 readings per second) over a large surface area. When the transducer is lifted off the surface, the average, lowest and highest thickness value is displayed making scan mode ideal for checking a sample’s overall uniformity.

With a user definable display, users can choose to view readings, statistical information, bar graph – an analogue representation of the current reading together with the highest (Hi) , lowest (Lo); and average (ẋ), reading or a run chart; a trend graph of the last 20 readings. For further information on display options, see pages 4 and 5.

The MTG6 has a single batch gauge memory and can store up to 1,500 readings. Compatible with both ElcoMaster® Data Management Software and ElcoMaster® Mobile Apps, readings can be downloaded via USB or Bluetooth® to PC, iOS or Android™ devices for further analysis and reporting.

Features of the Elcometer MTG6 Ultrasonic Material Thickness Gauge

• Pulsed-Echo (P-E), Echo-Echo ThruPaint™ & Velocity (VM) measurement modes
• 2-Point, 1-Point, Material, Velocity, Thickness Set and Factory calibration options
• User selectable measurement rate; 4, 8, 16 readings per second
• User selectable reading resolution; 0.1mm or 0.01mm
• Scan Mode
• Readings, Selected Statistics, Bar Graph & Run Chart
• Gauge memory; single sequential batch of up to 1,500 readings
• USB and Bluetooth® data output to ElcoMaster® and ElcoMaster® Mobile Apps

Echo-Echo ThruPaintTM (E-E) measurement mode enables readings to be taken on coated materials with a thickness range up to 25mm. In Echo- Echo ThruPaint™ mode, the coating thickness is ignored and the material thickness from the top surface of the material to the material density boundary is displayed. For further information on measurement modes, see the separate leaflet.

Compatible with  ElcoMaster® software, individual readings can be downloaded via USB to PC or similar device for further analysis.

The Elcometer MTG6 Ultrasonic Material Thickness Gauge conforms to the following standards :

• ASTM E797
• EN 14127
• EN15317

The MTG range of ultrasonic thickness gauges have been designed specifically to make them easy to use, calibrate, take readings and create inspection reports.

Accurate

With a measurement accuracy of ±1% up to 500mm in Pulsed-Echo (P-E) mode and 25mm in Echo-Echo ThruPaint™ (E-E) mode, accurate and repeatable readings can be taken on smooth, rough and curved, coated or uncoated surfaces. The stability indicator provides a visual indication of both the strength and reliability of the ultrasonic signal.

Efficient

The MTG4 has a set measurement repetition rate of 4Hz (4 readings per second).

Rugged

With a scratch and solvent resistant display, sealed, heavy duty and impact resistant design – dust and waterproof equivalent to IP54 – the MTG range is suitable for use in the harshest of environments.

All gauges have a fully customisable, scratch and solvent resistant colour LCD display. Measurement modes available include Pulsed-Echo (P-E), Echo-Echo ThruPaint™ (E-E) and Velocity mode (for more information on measurement modes, see page 19). A choice of measurement units are available, depending on the measurement mode selected. A stability indicator shows clearly both the strength and reliability of the ultrasonic signal.

Up to 8 statistical values can be displayed from a choice of number of readings (η) , lowest, highest and average reading (Hi, Lo, ẋ, ), standard deviation (σ), low and high limit values, nominal value and range.

A trend graph of the last 20 readings, showing the variation in material thickness over the test area. The graph is updated automatically as each reading is taken and any readings outside the set and enabled limits are displayed in red thus allowing the user to easily identify areas where corrosion may be present or the material is too thick for purpose.

When enabled, users can slide the transducer over a large surface area whilst the gauge takes readings at a rate of 16 Hz (16 readings per second). During each scan, the live thickness is displayed together with an analogue bar graph showing the thickness relative to the set nominal and any user defined limits, with audible and visual warnings if any readings fall outside set limits. When the transducer is lifted off the surface, the average, lowest and highest thickness value is displayed making scan mode ideal for checking a sample’s overall uniformity.

Velocity mode measures the speed of sound of materials and is ideal for determining the homogeneity of a material/alloy and the correct velocity of a material for calibration.
