Product Description

Elcometer MTG4 Ultrasonic Material Thickness Gauge

 

With a choice of calibration options and measurement modes, the Elcometer MTG4 Ultrasonic Material Thickness Gauge is ideal for taking readings on a wide range of coated and uncoated materials.

As well as all the features of the MTG2, the MTG4 has two calibration options. Using an uncoated sample of test material of a known thickness, the gauge can be calibrated using 1-Point calibration. Alternatively, the user can select one of 39 pre-set materials stored within the gauge including; aluminium, steel, stainless steel, cast iron, plexiglass, PVC, polystyrene and polyurethane.

Features

  • Pulsed-Echo (P-E) and Echo-Echo ThruPaint™ (E-E) measurement modes
  • 1-Point, Material and Factory calibration options
  • Pre-set measurement rate of 4 readings per second
  • USB data output to PC or similar device

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 MTG4 Ultrasonic Material Thickness Gauge conforms to the following standards :

  • ASTM E797
  • EN 14127
  • EN15317

Elcometer MTG4 Material Thickness Gauge Taking a reading - display

Easy

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.

 

 Elcometer MTG4 Ultrasonic Material Thickness Gauge Display The Display

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.
