Krautkramer-Branson's Meters D-Meters are considered to the "PRO" gauges used by inspectors that make a living with them and those with difficult tests to perform.   The DM-4 instruments can handle everything from very thin, small diameter pipes to thick and highly attenuative materials.  With the HT-1000 probe even pipes at 1,000° F. can be measured. Krautkramer has D-Meter probes covering almost every thickness testing application.

I - CORROSION / GENERAL PURPOSE GAUGES
StressTel's T-Mikes
T-Mike (P) Programmable
The T-Mike "P" is simple and easy to use. . While being one of the least expensive thickness gauges available, it is not a "cheap" instrument. It is ruggedly constructed, environmentally sealed, and uses standard AA batteries. The T-Mike "P" comes with a two year warranty. We consider it to be the best value in a ultrasonic thickness gauge for users who simply need to measure bare steel pipes, tanks and structures.

The T-Mike "P" is programmed for one sound velocity (usually steel). This fixed velocity means that a calibration is simply a matter of "zeroing" the probe. Simply couple the probe to the built-in probe zero block and the calibration is done. It’s that simple.
T-Mike E
The T-Mike E is like the T-Mike "P" but includes a velocity control to facilitate calibration when testing materials with different sound velocities, such as Aluminum, Stainless Steel, Monel, etc.
T-Mike ES
This instrument adds a minimum alarm together with increased pulse repetition rate to the T-Mike E for detecting small pitting when scanning.

While scanning, the green light turns to red whenever the instrument measures below a preset minimum.
T-Mike EL
The T-Mike EL has a 40,000 point Data Logger and a unique B-Scan graphical presentation of the scanned area. It's a great feature for "seeing" what's actually happening with your material.

When you scan the material with the B-Scan on, it draws a cross-sectional picture on the LCD display. When the probe is uncoupled, the minimum thickness is displayed.

It's very helpful for evaluating the extent of corrosion and determining whether you actually have a thickness reduction or have detected inclusions and laminations in the steel.

Krautkramer-Branson's D-Meters
DM4E
This instrument features a Probe Zero function that automatically corrects itself for probe wear and probe temperature changes. It also has 2 point calibration for the best measuring precision on thin, thick or hard-to-penetrate materials.

The "MIN-CAP" feature on all Krautkramer DM4E models increases the instrument's ability to detect pitting. This is done by pulsing @ 25 Hz (6 times higher than most other gauges). When the "Min-CAP" mode is selected, the DM4E's display is constantly updating while the probe is scanned over the material surface. The DM4E remembers the thinnest measurement encountered during the scan and displays this when the probe is uncoupled. This feature is great for "hot taps", drill tubes and many other applications requiring scanning to determine minimums.

We recommend wear resistant probes FH2E(WR) fingertip and KBA506(WR).
DM4
The DM4 has added features including: Four power settings, Low and High Pass Filters (for difficult applications), Hi/Low Alarms and a Differential Mode for Q.C. inspections.

PLUS!! The DM4 now offers Through-Coating Thickness Measuring Capabilities. You can now test painted tanks, pipes, etc., without needing to remove the paint or make corrections for the paint thickness.
The DM4 is the only hand held thickness gauge available with both through-coating and pitting detection capabilities in one simple, easy to use, hand-held gauge.
DM4DL
The DM4DL adds Data Logging (5,390 points in 999 files) with both computer interfacing and direct printer interfaces.  Output is compatible with Krautkramer's utility software, UltraMate™, Pipe+, UltraPipe™, and EPRI's boiler inspection software programs.
DMS
The DMS is the "Flag Ship" of Krautkramer-Branson's Ultrasonic Thickness Gauges.  The DMS has become the instrument of choice by Plant and Equipment Inspectors performing OSHA P.S.M. Process Safety Management Inspections in refineries, chemical plants,  power plants, and pipelines.

The DMS is also used to measure difficult, highly attenuative materials such as: fiberglass, composites, hot plastics, rubber and other difficult to test materials.

Easy to Use: Installation of UltraMATE™ is easy through the automated installation program. An intuitive user interface combined with extensive "on-line HELP" simplifies use and provides immediate access to details on program operation, features, and capabilities. UltraMATE™ is available on CD-Rom or 3.5" diskette formats. 

Direct DMS Communication: Simple, fast, bi-directional communication (send/ receive) is provided with the model DMS A-Scan thickness gauge's powerful alphanumeric on-board data recorder. Thickness values, A-Scans, Comments, Header Information, and Obstructs are communicated. An "Auto-connect" feature automatically selects the proper COM Port and BAUD Rate virtually eliminating communication problems. The DMS simply needs to be turned ON - no special settings or menu selections are necessary to communicate!

DM4 DL, DME DL, DMP DL, USN 50/52 Communication: UltraMATE now supports connection and download of datalogger files from these instruments. Once loaded into UltraMATE, data can be manipulated and exported.

Color Readings Reports: displays or prints readings in color based on user assignment of colors to thickness ranges. 

Copy and Paste: Provides a quick and easy way to get inspection data into standard spreadsheet (Excel) and word processing (MS-Word, Word Perfect) programs. Time consuming conversions to ASCII formats and export/import operations are eliminated. Copying data and pasting it within UltraMATE is now supported. This may be used to move data that was stored incorrectly when measurments where made.

Insert and Append: allows locations to be inserted and appended in existing files.

Comparison of Files: Provides an easy way to compare data files (old vs. new) on screen. Point-by-point comparison showing delta between values and % changes, as well as, a file summary showing average delta and % change.

Merge Files: allows up to five inspectors to work on a large job (i.e. boiler and storage tank walls) and then merge data into one single data file upon completion of the work.

Direct UltraPIPE Compatibility DMSMate and DataMATE III File Compatibility: UltraMATE can both IMPORT and EXPORT thickness data to both DMSMate and DataMATE III file formats. Saving thickness data to Tab, Comma, and Space delimited ASCII formats is also available. This allows data exports for use with many third party tools and applications.

III - HALL EFFECT GAUGES
MTM 10/20
The MTM 10 and MTM 20 handheld precision thickness gauges measure wall thickness of plastics, glass, ceramic, and other non-ferrous materials quickly, accurately and nondestructively.

Pinpoint wall thickness measurement is achieved when a small steel ball is attracted through the wall to be measured by the magnetic tip of a probe placed on the opposite side. The instrument instantly displays the digital thickness of the area located between the ball and the probe tip. Continuous measurements are carried out as the ball accurately follows the probe’s movement along the contour of a part.

Thin walls and components having extremely sharp curvatures are no problem since the small steel ball enables measurement of radii down to 0.03" (0.75 mm). Applications that cannot be solved by other measuring methods are possible with the MTM 10 and MTM 20 thickness gauges. Proven applications include all non-magnetic materials - plastics, glass, ceramic, nonferrous metals, wood, composites, etc. This technique offers blow molders an easy, accurate and nondestructive method to test wall thickness on sharp corners to ensure structural integrity of plastic bottles. Other packaging applications include glass containers, aluminum cans and thermoformed trays. Sampling, cutting and destroying parts are eliminated. Other difficult applications such as nonferrous metal casting, e.g. aluminum carburetor bowls, and plastic or rubber hoses can also be measured. Additionally, the gauges measure coating thickness when optional probes are used.

Select from two instrument models:
The small, extremely lightweight, handheld gauges, weighing only 9.5 oz.(270 g), are easy to use anywhere. Both models have memory capacity to store up to 10,000 readings. The PRT1 plug-in printer enables direct printout of the data, including statistical evaluation. When used with the MTM 20, limits can be set and histograms printed.
