The ultrasonic thickness measurement gauge uses a magnetic sensor to measure non-ferromagnetic coatings and coatings on ferromagnetic metal substrates such as steel, iron, etc., such as: paint, powder, plastic, rubber, synthetic materials, phosphating layer, chromium, zinc, lead , aluminum, tin, cad

(9) The effect of temperature. Generally, the speed of sound in the solid materials decreases with the increasing temperature. Test data shows that for every 100 °C increase in hot material, the speed of sound drops by 1%. For high temperature in-service equipment.This is often the case. High-temper

Ultra-thin materialWith any ultrasonic thickness gauge, when the thickness of the material is being tested below the probe's lower limit of use, measurement errors will result, and if necessary, the minimum limit thickness can be measured by the test block comparison method.When it is measuring ultr

Several methods in measurement1—Single measurement method: measurement at one point2—Double measurement method: Perform two measurements with a probe at one point. The probe crosstalk spacers should be perpendicular to each other in both measurements. Selecting the minimum value in the reading as th
