An Miao AT-140A Ultrasonic Thickness Gauge is a portable digital display ultrasonic Thickness Gauge with an external probe, which has the characteristics of small size, light weight, portability, and simple operation. AT-140A Ultrasonic Thickness Gauge is used to measure the material thickness of various ultrasonic good conductors, the measurement range is 1.0~200mm, and the resolution is 0.1mm.
* Using the optional RS-232C software and cable, it can communicate with the PC computer to realize the functions of data collection, processing, analysis and printing.
* Using computer technology, ultrasonic technology and many other professional technologies, it can accurately measure the thickness of materials.
* When the battery Voltage is lower than the specified value, it will be automatically indicated.
* Automatic memory material code and sound velocity value for easy use.
* Digital display, no parallax; with automatic shutdown and manual shutdown functions.
* With coupling status prompt function.
* It has strong transmitting power and high broadband receiving sensitivity. It can adapt to probes of different frequencies, so it can measure severely corroded rough surfaces, paint surfaces, and even some gray cast irons, and its application range covers almost all industries.

AT-140A ultrasonic Thickness Gauge is suitable for boilers, oil storage tanks, pipes, pipes, slabs, forgings, flanges, hulls, decks, Thickness measurement and corrosion measurement of rails, machined parts, etc. The AT-140A ultrasonic Thickness Gauge can be used to measure the thickness of most materials that can transmit ultrasonic waves , such as: metal, ceramics, plastics, nylon, glass, etc.





1) Lightly press the power switch to turn on the power of the whole machine.
2) Press the mm/inch switch lightly to select the appropriate measurement unit.
3) On the premise of confirming that the code of the tested material is selected correctly, couple the ultrasonic sensor to the tested material well. The reading on the display is the measured value.
4) The retention time of the measured value depends on the arrival time of the next measured value. If the measurement stops, the thickness value will be retained until the power is turned off.
5) After the measurement is completed, turn off the power of the whole machine.
At any time, just press the power button once to manually turn off the power of the whole machine; on the other hand, if no button is pressed within 2 minutes, it will automatically shut down to realize the power saving function.
