Precision Thickness Measurement Gauge

Precision thickness gauges measure material thickness using methods such as ultrasonic waves, eddy currents, or radiation. The probe contacts or approaches the sample to emit signals, and the reflected waves are received to calculate the time difference or energy attenuation, thereby obtaining thickness data. They are used for thickness detection and quality control of coatings, films, and sheets.
Selection
When selecting, consider the material type, such as using eddy current for metals and ultrasound for non-metals; ensure the measurement range covers the sample thickness; the accuracy must meet process requirements; the probe size should be compatible with the inspection area; account for environmental factors like temperature affecting calibration; the operation interface should be simple and easy to read; and it must comply with industry standards such as ISO and ASTM.
