How to Use Digital Surface Profile Gauges 

Before taking measurements, calibrate the gauge using the provided reference surface. Take a series of 5 or 10 consecutive measurements over a defined area, ensuring the probe is positioned at a 90-degree angle to the surface. For a more precise study, perform 5 series of five or ten measurements for an area of approximately 1 m². 

Reporting and Data Transfer 

Digital surface profile gauges come with storage and data transfer capabilities. Measured data, statistics, and threshold limits can be transferred via USB or Bluetooth to create professional reports and graphs on your mobile phone or laptop.

Answers to your questions

Digital gauges are robust, easy-to-use, and provide instant measurements, making them ideal for assessing shot-blasted surfaces on flat or curved areas. They’re also shock-resistant, waterproof, and compliant with international standards like ASTM and SSPC.

To ensure accurate readings, calibrate the gauge carefully using the reference glass plate provided. Take a series of 5 or 10 consecutive measurements in a 10 cm diameter area per the local standard (ASTM D4417 or SSPC-PA 17), positioning the probe at a 90-degree angle to the surface. Calculate the average heights or maximum measured value between the peaks and valleys created during shot-blasting for a precise evaluation.

Digital gauges offer a simple and fast testing method, covering a 1 m² surface in just a few minutes. They’re adaptable to various part configurations, with models designed for flat or curved surface measurements.

There are two key international standards, ASTM D4417 and SSPC-PA 17. They provide guidelines for using digital surface profile gauges. Both address assessing abrasive blast cleaned metal surfaces. The standards guide calibration and usage procedures, making them vital in industries where surface profile is crucial. The choice of gauge model depends on your specific needs.
