The Elcometer MTG6 Ultrasonic Material Thickness Gauge (part numbers MTG6DL gauge only and MTG6DL-TXC with transducer) is an ultrasonic gauge with extended calibration, measurement and data-logging options for taking readings on a wide range of coated and uncoated materials and downloading the data for analysis and reporting. Ultrasonic thickness testing is a non-destructive method used where only one side of the material is accessible, such as pipelines and storage tanks, making the Elcometer MTG6 Ultrasonic Material Thickness Gauge suited to monitoring corrosion and erosion and keeping a record of measurements over time.
The Elcometer MTG6 Ultrasonic Material Thickness Gauge offers Pulsed-Echo (P-E) mode over 0.63 to 500 mm, Echo-Echo ThruPaint (E-E) mode over 2.54 to 20.00 mm for measuring through coatings, and Velocity Mode (VM), which is used to determine the homogeneity of a material or alloy and the correct velocity for calibration. The velocity range is 1250 to 10,000 m/s and accuracy is plus or minus 1 percent or plus or minus 0.05 mm. The measurement rate is user selectable at 4, 8 or 16 Hz, with a high speed scan mode for covering a large surface area, and reading resolution is selectable at 0.1 mm or 0.01 mm. Calibration options for the Elcometer MTG6 Ultrasonic Material Thickness Gauge include 2-point, 1-point, material, velocity, known thickness value and factory reset.
Display can be set to readings, selected statistics, a thickness bar graph or a run chart. The gauge memory of the Elcometer MTG6 Ultrasonic Material Thickness Gauge stores a single sequential batch of up to 1,500 readings, and data is output via USB and Bluetooth to ElcoMaster and the ElcoMaster Mobile App on PC, iOS or Android devices. The Elcometer MTG6 Ultrasonic Material Thickness Gauge is tough, waterproof and dust resistant to IP54, with a 2.4 inch TFT colour screen, ambient light sensor and emergency light, and carries a 2 year warranty. It conforms to ASTM E797, EN 14127 and EN 15317. Used in NDT, corrosion and coatings inspection, and supplied by BAMR, South Africa's authorised Elcometer distributor.

When to use the Elcometer MTG6
You need to measure material thickness on a range of coated and uncoated parts, then download the figures for analysis and reporting. The MTG6 takes readings through paint, logs them on the gauge and transfers them to ElcoMaster for documentation. It suits inspectors who measure across mixed materials and want their data tidied up afterwards.
- 1Reads through applied paintEcho-Echo ThruPaint mode reports true metal thickness without stripping the coating, so you can check a painted structure in place rather than grinding back to bare substrate.
- 2Three measurement modes on one gaugePulsed-Echo, Echo-Echo and Velocity modes let you switch between coated work, uncoated work and velocity checks without carrying a second instrument to site.
- 3Logged data straight to ElcoMasterA single batch of up to 1,500 readings transfers over USB or Bluetooth, so you build a report from recorded values instead of writing readings down by hand.
- 4Fast scanning for thin-point huntingScan Mode at up to 16 readings per second lets you sweep an area to find the thinnest point quickly, useful when you are screening a surface rather than spot-checking.

Frequently asked questions
What measurement modes does the MTG6 support and how do they differ from the MTG2?
The MTG6 adds Echo-Echo ThruPaint (E-E, range 2.54 to 20.00mm) and Velocity Mode (VM) to the Pulsed Echo (P-E) mode. The MTG2 supports P-E only. P-E range is 0.63 to 500mm across all models.
How accurate is the MTG6 compared with the entry-level MTG2?
The MTG6 is rated plus or minus 1% or plus or minus 0.05mm, a finer floor than the MTG2's plus or minus 0.1mm. Resolution can also be set to 0.01mm on the MTG6 versus 0.1mm on the MTG2.
What data logging capability does the MTG6 have?
The MTG6 logs up to 1,500 readings in a single batch with sequential batching, date and time stamping, delete last reading, and batch review functions. Data transfers via USB or Bluetooth to computers and Android and iOS devices.
What calibration options are available on the MTG6?
The MTG6 supports zero set via the integral disc, 1-point, 2-point, material selection from 39 presets, factory reset, velocity calibration, and known thickness calibration. Calibration lock with optional PIN and a test calibration feature are also included.
What display modes and on-screen statistics can the MTG6 show?
The MTG6 can display a reading, selected statistics, scan thickness bar graph, and run chart. On-screen statistics include number of readings, mean average, standard deviation, and lowest and highest readings.
How is the MTG6 powered and what is the battery life?
The MTG6 uses two AA batteries. Alkaline cells give approximately 15 hours and lithium cells approximately 28 hours. The gauge can also be powered via USB from a PC.
