The tester employs a double crystal transducer consisted of two independent crystals separated by an acoustic barrier. When the ultrasonic pulse emitted by one of the crystal sensors of the probe reaches the demarcation surface through the material to be measured, the pulse will be reflected, and received by another crystal sensor. The professional timing chip inside the instrument precisely records the time of ultrasonic wave propagation in the material, and finally the instrument determines the thickness of the material with time and velocity. The measuring range of the tester is 0.8mm-300mm, capable of testing the most engineering materials, including metals, plastics, ceramics, glass, glass fiber and any other ultrasonic good conductor. VTSYIQI Ultrasonic Thickness Gauge Meter Tester Measuring Instrument With Range 0.8 to 350mm 0.031 to 13.779inch for Metal Glass Ceramics PC Material Pipes Steel Sound Conductor Test In many industries, It is essential to mesure the wall thickness to confirm the condition of the material for the normal running of the items or structure safety. ultrasonic thickness meter can be widely used in testing the thickness of various accessories or metallic structure to check them whether to be repaired or changed such as ships, tanks, pipes or steel structure. The gauge is applicable for petroleum, chemical, metallurgical, shipbuilding, aviation and aerospace various fields. 1. Ultrasonic double crystal probe The gauge probe employs a double crystal transducer consisted of two independent crystals separated by an acoustic barrier. One crystal sends ultrasonic pulses, and another is responsible for receiving them. The probe is highly sensitive and can effectively reduce clutter, and the probe housing is made of stainless steel, which is hard and durable 2. Sound velocity can be measured according to thickness The tester can reverse the sound velocity of the material based on the known thickness and measurement results. And the instrument can test irregular materials of the same components as the materail whose thickness can be measured 3. Built-in sound velocity of multiple materials already contains the velocities of several common metallic (such as iron, copper, aluminum) and non-metallic materials (plastics, ceramics, plexiglass) as well as other objects and the user are not required to find them separately 4. Excellent Timer chips provide fast, accurate readings ultrasonic thickness gauge calculates the material thickness by sound velocity and the time taken between the emitted pulse and the detected echo, a precision timing chip can bring the user the accurate time to get the accurate data 5 .Automatic Gain switchable Some materials are good conductors of sound and some are not. For the latter, the meter can switch the Gain freely which is to amplify the ultrasonic signal so that the emitted pulse is accurately captured by the transducer as it propagates, and obtains accurate data 6 .Automatic Gain switchable Some materials are good conductors of sound and some are not.

Two measurement modes: QC Mode/Statistics Mode ultrasonic thickness tester features two measurement mode: QC mode and statistics mode. Allowing to set upper and lower limits to check the problem areas by prompting NG under the QC mode. It will count maximum, minimum and average values of data in Statistics mode. 8.
