MicroMeter Film Thickness Gauge

The micrometer thickness gauge measures coating thickness using ultrasonic or eddy current principles. The probe contacts the material surface to emit signals and receives reflected waves, calculating the time difference to determine the thickness value. It is used to detect the thickness of coatings such as paint, electroplated layers, and plastic films, ensuring that products meet specification requirements.
Selection
When selecting, consider the measurement range covering the sample thickness, and choose magnetic induction for ferrous materials or eddy current for non-ferrous materials. Use a small probe for curved surfaces and a high-frequency probe for rough surfaces. Environmental temperature affects accuracy, so it is necessary to match with calibration standard blocks. Portable models are suitable for on-site use, while benchtop models are suitable for laboratory applications.
