select points

Measuring range: Choose a measuring range that can cover the range of dry film thickness that needs to be measured. Generally speaking, you should choose a measuring instrument that is wider than the thickness range that needs to be measured in order to better adapt to practical applications.

Measurement accuracy: Measurement accuracy is an important indicator for choosing a dry Film Thickness Gauge. An instrument with high precision and small error should be selected to ensure the accuracy and reliability of the measurement results.

Probe shape: Select different shapes of probes according to the shape and surface state of the coating to ensure the accuracy and precision of the measurement.

Display method: There are two methods of digital display and graphic display. The digital display method is usually more accurate than the graphic display method, but for non-professionals, the graphic display method is easier to understand.

Software function: Choose an instrument with data storage, export, analysis and other functions to manage and analyze measurement data more conveniently.

Precautions

  • Maintenance and calibration of the instrument: Regular maintenance and calibration of the dry Film Thickness Gauge to ensure the accuracy and stability of the measurement results.

  • When measuring, attention should be paid to the flatness, uniformity and cleanliness of the surface of the coating to be tested to avoid interference with the measurement results.

  • Pay attention to the measurement angle and position when measuring to ensure the accuracy and repeatability of the measurement results.

  • Select the appropriate measurement mode, such as single measurement, continuous measurement, etc., according to the actual application needs.

  • For different types of coatings and coatings, appropriate probes and measurement parameters should be selected to ensure the accuracy and reliability of measurement results.

  • After the measurement, the instrument should be cleaned in time and kept in a dry state to avoid damage to the instrument.
