Solving Various Difficult ThicknessMeasurement



2.4”color OLED, 320 X 240 pixels, display contrast 10,000:1

Live Color A-Scan


Users could directly see the color ​waveform of the ultrasonic sound (or A-scan) on the screen, which is quite ​important for the occasions that we need to check the correctness of the ​testing results. Many cases will cause wrong testing results or even noreadings. ​We could find the causes easily through the A-scan. Adjust the three parameters ​of GAIN, BLACKING, GATE, and then we will get the right readings.

Live Color B-Scan



TM281 series thickness gauge has time ​base B-scan function. Move the probe along the workpiece surface, then the ​cross -sectional profile of the workpiece display, use for observe the ​underside contour of the workpiece.It could be automatically capture a minimum ​value of the B-scan image, and indicate the position of the minimum by a red ​triangle. You can see any point thickness value of the B-scan image by moving ​the pointer.

Through Coating FunctionNo longer ​need to waste time to remove the coating

Now TM281D and TM281DL also have this ​widely acclaimed function. It's realized by measuring the two continuous bottom ​surface of the substrate. This mode also has more advantages:

  1. Exempt Zero Calibration
  2. High Stability, the measuring value is not influenced by the probe pressure, the ​coupling layer thickness and the surface dust of the workpiece.
  3. Zero Drift


More Practical Function

Difference/Reduction ​Rate: Difference mode ​displays the difference between the actual value and the normal value. ​Reduction rate calculates and shows the percentage of the thickness reduction ​when the material becomes thin. Typical application is to measure the metal ​material which is due to bending and becomes thin.

Information displays: LOS, min, max, large reading while displaying min at the ​same time, velocity, zero, calibration, units, freeze, unfreeze, % battery life ​remaining, gain - low, std, high, echo to echo symbol

Max./Min. Capture: On this ​mode, the current thickness, minimum thickness and the maximum thickness will ​be shown on the screen at the same time.

Alarm Mode: Dynamic change the ​color of thickness readings when alarming.

Update Rate: Selectable 4Hz, 8hz ​and 16Hz. 4Hz for ordinary application, when you need a quick scan, such as ​high temperature measurement, you can choose higher update frequency.

Multi- Languages Available: Chinese,English, Spanish, German.

Echo to Echo: Measures the metal thickness only (ignore paint and ​coatings)

Data logger: 99999 ​thickness data logger with ID point in linear or grid files ( 400 files)

Output: USB 2.0 full ​speed connector. DataView report software

Temperature: Gage Operating:-10° C to 50° C

Standard TM510 Probe

The probe is the heart of the ​instrument,TMTeck has the world’s leading probe production technology. TM510 ​probe uses the high performance piezoelectric ceramic chip, with integrated ​metal die-casting shell, practical design of probe and cable separated, ​regardless of costs to create high quality .
