How to Measure Surface Profile using the Elcometer 224 Digital Surface Profile Gauge

PLEASE NOTE: This video is part of "Understanding Surface Profile with the Elcometer 224 Digital Surface Profile Gauge".

Watch the full video here:


In the coatings industry, it is vital to measure surface profile to ensure it is within the predefined specification, otherwise a profile that is too high or too low could lead to costly premature coating failures and corrosion.

So, how do you measure surface profile?

3:33 - Why you need to take multiple surface profile readings
5:06 - The Elcometer 224 and ElcoMaster App

PLEASE NOTE - If you have an Elcometer 224 gauge that was released before 1st March 2019, you can update the software of your gauge to include the new measurement modes feature by connecting the gauge to the latest version of ElcoMaster for PC via USB cable.

In the industrial and protective coatings industry, metal surfaces are either chemically etched, mechanically abraded, or blasted; to among other things, generate a surface profile. The surface profile increases the surface area, which provides a key for the coating to adhere or stick to.

If the surface profile is not within specification, and is either too large or too small, this can lead to costly premature coating failures and corrosion. So that’s why it is important to measure surface profile.

There are a number of methods for measuring surface profile, and they all work in different ways.

Surface Comparators are flat, metal plates, which contain a number of reference surface profiles. The comparator is placed on the surface, which is compared with the reference profiles through either sight or touch. The profile is determined and recorded.

A widely used alternative is the Replica Tape method.

A tape with a compressible foam pad is applied to the surface, and rubbed with a burnishing tool. By rubbing the tape into the surface, the foam is pushed down, creating an inverse or mirror image of the profile. The tape is then removed and measured using a thickness gauge, such as the Elcometer 124 gauge. The replica tape method provides a peak-to-valley height measurement of the profile.

A faster, more accurate, and repeatable method for measuring surface profile is the new Elcometer 224 Digital Surface Profile Gauge.

The Elcometer 224 is a needle depth gauge, which is very easy to use. Simply zero the gauge on glass, and, when the gauge is placed on the surface, a spring mounted needle measures the depth of the profile from the peaks of the profile at that particular point.

With the ability to measure profiles up to 500 microns (20 mils), on flat or curved surfaces, the Elcometer 224 Digital Surface Profile Gauge provides repeatable and reproducible measurements accurate to ±5%.

The Elcometer 224 can store each reading into memory (150,000 readings in 2,500 batches) – and can instantly transfer them to your PC or mobile device using ElcoMaster; our free, easy-to-use software application, generating professional inspection reports, instantly.

Taking just one reading on a blasted surface will not be representative of the entire surface profile, as the needle could rest in a valley or on any part of the slope. That is why you need to take a number of readings over a small area to get a statistically valid measurement.

That’s why most test methods or standards recommend you take multiple readings in one location; some say ten (ASTM 4417-B), others say five (SANS 5772); and again depending on the standard you should record either the maximum or average of these readings.

The new Elcometer 224 Digital Surface Profile Gauge can store either the average or maximum peak to valley height reading into memory. Alternatively, if you want to store every value, simply select the gauge’s Immediate mode.
