Ship manufacturing factory steel plate thickness gauge, Aotai steel plate thickness detectorAT -700, It is a new generation intelligent ultrasonic thickness gauge from Jining Aotai, which adopts high-performance and low-power microprocessor technology. Based on the principle of ultrasonic measurement, it can measure the thickness of various materials such as metal, glass, ceramics, and measure the sound velocity of materials. Widely used for thickness measurement of various sheet materials, pipe wall thickness, boiler vessel wall thickness, various pipelines and pressure vessels, and shipbuilding industries, monitoring their degree of thinning after corrosion during use.

Ship manufacturing factory steel plate thickness gauge, Aotai steel plate thickness detectorMain functions:

Suitable for measuring the thickness of good conductors of metals (such as steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, fiberglass, and any other ultrasonic waves

Can be equipped with multiple twin probes of different frequencies and chip sizes for use

Equipped with probe zero point calibration and two-point calibration functions, it can automatically correct system errors

Knowing the thickness can be used to measure the speed of sound in reverse order to improve measurement accuracy

Equipped with coupling status prompt function

Equipped with LED backlight display, convenient for use in low light environments

There is a remaining battery level indicator function that can display the remaining battery level in real time

Equipped with energy-saving functions such as automatic sleep mode and automatic shutdown

Compact, portable, highly reliable, suitable for harsh operating environments, resistant to vibration, impact, and electromagnetic interference

Advantages of AT-700

Other models of thickness gauges in the same price range

Menu style operation, high brightness LCD display,

Equipped with LED backlight

Broken code EL display, high power consumption, difficult to see in dark environments

2. Adjustable sound speed, capable of measuring various materials

Low priced manufacturers only have the sound velocity of 5920 steel

3. Multiple probes (coarse crystal, small tube diameter, high temperature) can be equipped without calibration, automatically identifying and calibrating

Cannot automatically recognize multiple probes

4. There is a minimum capture indication

No ability to capture with minimal thickness

5. Can store 500 sets of data and 5 files

Can only store 50-100 sets of data

6. Internally, a highly integrated motherboard is used, with all chips being * and stable performance!

Most of them use two circuit boards and mostly use domestic components with unstable performance
