– 2 –1.0 INTRODUCTIONThe Checkline model TI-25MX is a basic dual element thickness gauge with the abilityto locate blind surface pitting and internal defects/flaws in materials. Based on the sameoperating principles as SONAR, the TI-25MX is capable of measuring the thicknessof various materials with accuracy as high as ± 0.001 inches, or ± 0.01 millimeters.The principle advantage of ultrasonic measurement over traditional methods is thatultrasonic measurements can be performed with access to only one side of the materialbeing measured.1.1 DisclaimerInherent in ultrasonic thickness measurement is the possibility that the instrument willuse the second rather than the first echo from the back surface of the material beingmeasured. This may result in a thickness reading that is TWICE what it should be.Responsibility for proper use of the instrument and recognition of this phenomenon restsolely with the user of the instrument. Other errors may occur from measuring coatedmaterials where the coating is insufficiently bonded to the material surface. Irregularand inaccurate readings may result. Again, the user is responsible for proper use andinterpretation of the measurements acquired.
