Overview
MT660 Multimode Ultrasonic Thickness Gauge is an upgraded product launched by MITECH, focusing on user experience and functional innovation. It uses a high definition color LCD screen, which can be clearly displayed in dim or strong light environments. The instrument uses a sealed aluminum magnesium alloy shell, which is rugged and durable, and is specially designed to defend against oil, dust and other harsh environments. It has intelligent warning function, supports 0.001mm High Accuracy Display, Bluetooth communication, and has both penetrating coating mode and normal mode, and can directly measure the substrate Film thickness without removing the surface coating. Widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields, used for monitoring equipment corrosion thinning or precision measurement, is a professional instrument to improve efficiency and pass rate.

Principle
The MT660 Ultrasonic Thickness Gauge performs film thickness measurement based on the principle of ultrasonic pulse reflection. In the transmit-echo mode, the Probe emits ultrasonic pulses to the material under test. After the pulses reach the bottom surface of the material, they are reflected back. The instrument calculates the film thickness of the material by measuring the round-trip time of ultrasonic waves propagating in the material, combined with the known speed of sound. In the echo-echo mode, the instrument can identify and utilize the primary and secondary echoes of the bottom surface of the material, so that when measuring the coated workpiece, it is possible to effectively penetrate the surface coating, and only measure the film thickness of the substrate without measuring the film thickness into the result.
Applications
Monitoring of Corrosion and Thinning Degree of Pipes and Pressure Vessels in Production Equipment in Petroleum, Chemical Industry, Metallurgy, Shipbuilding, Aviation, Aerospace and other Fields, Accurate measurement of various plates and various processed parts
Standards
The data did not mention specific compliance criteria
Steps
1. Select the appropriate Probe according to the tested material and connect it.
2. Turn it on and select the measurement mode (transmit-echo mode or echo-echo mode) as needed.
3. Probe calibrated (zero point calibrated or two point calibrated).
4. Set or confirm the speed of sound of the material under test (or measure the speed of sound using known Film thickness).
5. Apply a coupling agent between the surface of the Probe and the surface of the material under test.
6. The Probe is smoothly coupled to the measured point, and the measurement results are read and recorded.
7. You can choose single point measurement, maximum value measurement or difference measurement and other viewing modes.
8. The measurement data can be saved or transferred to a computer or printer through Bluetooth and USB interfaces.
Notice
• Before measurement, make sure that the Probe is well coupled with the measured surface, and the instrument has a coupling status prompt function.
• Select the appropriate measurement mode and Probe according to the type of material being tested, Film thickness and surface condition (e.g. coating).
• Before making accurate measurements, be sure to calibrate the instrument using a standard test block.
• When measuring coated workpieces in echo-echo mode, ensure that the coating is uniform and well bonded to the substrate.
• Pay attention to the operating temperature of the instrument (0 ° C to + 50 ° C) and the storage temperature range (-20 ° C to + 70 ° C).
• The relative humidity of the working environment should be ≤ 80%.
• Pay attention to the remaining battery power indicator in time, and it is recommended to take out the battery when not in use for a long time.
• The instrument has an automatic alarm function, which can preset the upper and lower limits of Film thickness, and will prompt when it exceeds the range.
