Elcometer MTG6 Ultrasonic Material Thickness Gauge

Product Description

With a choice of calibration options, measurement modes – including high speed scan mode, display options and data-logging, the MTG6 is ideal for taking readings on a wide range of coated and uncoated materials and downloading data for further analysis and reporting. As well as all the features of the MTG2 & MTG4, the MTG6 has additional calibration options; 2-Point, Velocity and known Thickness Value. Measurement Mode 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. Display Mode 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 (x), reading or a run chart; a trend graph of the last 20 readings. Data Logging & Data Output The MTG6 has a single batch gauge memory and can store up to 1,500 readings. Compatible with both ElcoMaster® and ElcoMaster® Mobile Apps, readings can be downloaded via USB or Bluetooth® to PC, iOS or Android™ devices for further analysis and reporting.

The Elcometer MTG range of ultrasonic material thickness gauges accurately and non-destructively measure the thickness of materials when only one side is accessible – ideal for monitoring corrosion and erosion. Contents 0:23 – Introducing the Elcometer MTG range 2:14 – How dual element transducers work 3:22 – Transducers and the Elcometer MTG 3:54 – Key features of the Elcometer MTG range 5:21 – Calibrating the Elcometer MTG range 5:52 – Elcometer MTG and ElcoMaster Capable of measuring almost any coated or uncoated material, for a wide range of applications – including steel pipelines and storage tanks, porcelain basins, plastic piping, or rubber linings to name a few – the Elcometer MTG range is made up of four models: – The entry-level Elcometer MTG2, a pre-calibrated gauge which simply measures the thickness of uncoated steel; – the Elcometer MTG4 and MTG6, which can measure a wide range of materials even when they’re coated; Despite their differences, every model in the Elcometer MTG range has a simple, intuitive menu system in multiple languages, so they are easy-to-use without compromising on features or functionality; dust and waterproof equivalent to IP54, ideal for use in the harshest of environments; and accurate to 1% – making this range of Elcometer NDT gauges versatile and reliable. With the ability to measure the thickness or sound velocity of most materials – such as metals, plastics, glass, epoxies, and ceramics – the Elcometer MTG range uses a dual element transducer, and a small amount of ultrasonic couplant, to measure the substrate thickness, even when it is coated with up to 2mm of paint; ideal for when you need to measure the thickness of a coated material without damaging the coating. The Elcometer MTG thickness gauges are designed to work with Elcometer’s range of intelligent transducers, which all have automatic probe recognition – so as soon as the transducer is connected to a gauge, the gauge immediately detects what type of transducer you’re working with. If you already have a range of transducers you wish to use which have Lemo Connectors; they can be connected to the Elcometer MTG gauges using a dual element transducer adaptor – all you have to do is tell the gauge what transducer you are using. The Elcometer MTG gauges have user selectable measurement rates of up to 16 readings per second (16 Hertz); ideal for quickly scrubbing across a surface, recording multiple measurements. If you are measuring large surface areas, the Elcometer MT6 and MTG8 have scan mode, where you can scrub the transducer over the test area, and the gauges will display the average, lowest, and highest thicknesses across the scanned area. In addition to displaying the material thickness, the Elcometer MTG6 and MTG8 ultrasonic gauges have a choice of displays, ensuring the information you need is on screen, when you need it. The Elcometer MTG range have several calibration options; with simple, on-screen instructions that guide you through each method – so it’s easy to maintain the gauge’s accuracy, at all times. To find out more about all of the calibration methods, make sure you watch our Ultrasonic NDT calibration videos. The Elcometer MTG8 also allows you to programme up to 3 calibration memories, so you can select a saved calibration method without the need to re-calibrate the gauge.
