With the patented “TopCOAT“ method (DMS 2TC) we have been able to optimize the corrosion measurement through paint coatings: this method makes it possible to measure materials showing heavy corrosion on backwall surfaces, and even the slightest pitting can be detected thanks to a high gain. The paint coating and base metal are measured in one measurement process, and displayed simultaneously.

If your components are uncoated, you have the Auto-V feature at your disposal. It is a clearly simplified version of the conventional thickness measurement and, as such, a unique method. Auto-V even allows you to measure the thickness of components with unknown material velocity. This enables you to measure different uncoated materials without any additional calibration – and without any calibration standards. It’s not necessary to know the material velocity to be able to measure – this previous disadvantage no longer exists.

The DMS 2 does not only display the A-scan for you to have your measurement better under control. You can also view your measurement results as a B-scan, i.e. a timed cross-sectional view of the material thickness. With this feature, the DMS 2 offers you an additional graphic display mode ideal for checking corroded sections and for detecting the minimum reading in a certain area. Just look at the large-digit display that you can select as required – another advantage for your on-site work.

The DMS 2 is truly suitable for field use with its small size and its weight of only 1.95 lbs (including batteries). The membrane keypad and housing are of course likewise designed for industrial environments. The operating time of the rechargeable batteries is enough for a whole week’s work.

The enhanced ergonomic shape ensures easy one-handed operation. The operating concept is straight-forward and easy to learn – with quick access to functions.

Measurements on components showing strong corrosion, through coatings, on unknown materials – the DMS 2 offers a large number of optimized and field-proven performance features and capabilities:

• Automatic recognition of all dialog probes for optimum instrument setup and performance, as well as for the documentation.
• Enhanced single-element mode for the connection of several probes, also for precision thickness measurements.
• Automatic probe zeroing for the precise setting of the instrument to different probes and test conditions.
• Minimum-capture mode with increased pulse repetition frequency for the display and storage of the minimum reading.
• RF display mode, four automatic band-passes, selectable display update rate, and much more.

• Impact resistant, dust and waterproof housing with rubber field case for tough conditions
• Large LCD with backlight for display of digital readings, A-scans and B-scans as well as the instrument settings.
• Large A-Scan display for signal measurement verification and adjustment
• Dual-Multi mode for thickness measurements on coated surfaces
• TopCOAT method - measurements of the paint coating and base material are determined and simultaneously displayed in one measurement, even when the backwalls are corroded
• Auto-V - enables thickness measurements to be made on components with unknown sound velocities without the need of a reference block.
• 40 hour operation period with standard AA AlMn batteries
• Quick access to instrument settings and functions by user-friendly menus
• Data memory for adjustment data sets with alphanumeric coding
• Flexible data recorder with alphanumeric data input
• Serial RS-232 interface for data transfer to the PC or a serial printer
• Optimum performance with dialog probes and automatic zero point recognition with all probes
• Solve a variety of applications with the most versatile probe selection available.

is the high-contrast, state-of-the-art LCD providing good readability even in the brightest sunlight – and at a very unfavourable viewing angle. You can adjust the contrast to match all ambient light conditions, and if you’re in a dark environment, just switch on the backlight.

The DMS 2’s on-board Data Recorder makes all the options for up-to-date documentation and modern data management available to you:

• Memory capacity for 150,000 readings and 1,100 A- or B-scans (extendable)
• Flexible adaptation to the measurement task by eight different file structures – according to the arrangement of measuring points most often encountered.
• Subsequent insertion/deletion of readings within a file
• Storage of additional information for each measurement location: probe, material velocity, date, time, calibration, etc.
• Comment line with 64 characters accessible at any time.
• Microgrid: You can insert up to 81 readings, in 2 x 2 to 9 x 9 grids, per measurement point at any time during the test using this function. By doing this, an analysis can be made in the direct vicinity of a critical measurement point.

Despite the extensive performance scope of the Data Recorder – its operation is simple. For example with the navigation: you don’t only see your current reading, but also – for a better overview – the surrounding measurement locations.

For your alphanumerical data inputs we have created the “Virtual Keyboard“ which is displayed on the DMS 2 screen and makes it easy for you to input data.

You will receive a test report via a connected printer at the press of a key. There’s a wide selection of special application software at your disposal for further data processing.

These programs enable you, e.g. to transfer measurement data to a PC and back again, to transfer the data to other standard programs – such as Microsoft Excel – and to analyze them there, manage them in a database or integrate them into quality management systems.

Thickness measurements on hot components are no problem with the DMS 2. We have different dual-element probes in our delivery program allowing to reliably measure components at high temperatures up to 600 °C, including coupling monitoring.

You can now forget the time-consuming removal of coatings. The TopCOAT function of the DMS 2TC helps to measure not only the thickness of the base metal, but at the same time also that of the coating layer. Moreover, you’ll have other possibilities of measuring through coatings at your disposal under certain conditions, e.g. measurement within the echo sequence (Dual-Multi function).

Special probes with reduced contact face enable you to measure the remaining wall thickness even at points which are normally hardly accessible: on components showing strong pitting or surface roughness due to external corrosion.

Using the Auto-V function, you can now measure components with unknown material velocity – without any previous comparison measurement by mechanical means! Other advantages: measuring errors in the case of material velocity variations due to temperature variations – e.g. with plastic materials – or due to inhomogeneous materials – e.g. grey cast iron – are eliminated; testing reliability therefore increases.
