Measure Blast-Cleaned Surface Profiles Directly on Flat and Curved Surfaces
The Elcometer 224 Digital Surface Profile Gauge provides fast, direct measurement of peak-to-valley surface profile before protective coatings are applied. Designed for blast-cleaned surfaces, it helps inspectors verify that the prepared substrate has the required profile for the coating system and project specification.
Unlike replica-tape methods, the Elcometer 224 takes measurements directly from the surface using a durable tungsten carbide stylus. It measures profiles up to 500µm (20mils), provides real-time statistics, and is available with integral or separate probes to accommodate different inspection requirements.
ELCOMETER 480 MODEL SPECIFICATIONS
The Elcometer 224 surface profile meter is available in two different models: Model B and Model T. Standard and armoured probes are available for the separate models, providing even greater measurement flexibility. These probes are supplied with a glass zero plate, calibration test foils (nominal values 125µm (5.0mils) & 500µm (20mils)) and an Elcometer Test Certificate.

Flat Surface Profile Probes
Supplied with either standard cables or armoured metal reinforced heavy duty cables, Elcometer surface profile probes are supplied with a glass zero tile, calibration test foils (nominal values 125 μm (5.0mils) & 508μm (20mils)) and an Elcometer test certificate.

Understanding surface profile gauge measurement
1. Ensure probe is 90° to substrate to ensure accurate readings and calibrate the
gauge on a glass zero tile.
2. To take one spot measurement, take either 5 or 10 readings within a 100mm
(4”) diameter area.
3. The measurement displayed is either the average peak-to-valley height or the
maximum reading of the 5 or 10 readings, depending on which measurement
mode you have selected.
4. To establish the average surface profile of an area, record 5 spot measurements
for each 1m x 1m (3ft x 3ft) area.
Integral gauges are ideal for single-handed operation as the wide footprint provides greater stability during surface profile analysis.
Direct Peak-to-Valley Profile Measurement
The gauge measures the depth from the peaks to the valleys of a prepared surface. Its 60° tungsten carbide probe tip has a 50µm (2mil) radius and provides a measurement range of 0–500µm (0–20mils), with 1µm (0.1mil) resolution and accuracy of ±5% or ±5µm (±0.2mil).
Measure Flat and Convex Surfaces
Integral and separate probe configurations are available for different geometries. Dedicated convex probes allow surface profile measurements on curved components and pipes with diameters as small as 75mm (3in), making the system particularly useful for pipelines, tanks, structural components, and fabricated equipment.
More Than 50 Readings Per Minute
The Elcometer 224 can capture more than 50 readings per minute with standard probes, allowing inspectors to characterize large prepared areas considerably faster than methods requiring a separate replica and subsequent measurement. Convex probes can take up to 25 readings per minute.
Average or Maximum Peak-to-Valley Measurement
For a spot measurement, the instrument can take either 5 or 10 readings within a 100mm (4in) diameter area. Depending on the selected measurement mode, the displayed spot result can represent either the average peak-to-valley height or the maximum reading from the measurement set.
Real-Time Statistics During Inspection
The gauge automatically calculates key statistics while measurements are being taken, including number of readings, mean, standard deviation, highest and lowest readings, and coefficient of variation. User-defined high and low limits can also provide audible and visual warnings when measurements fall outside the specified range.
Integral or Separate Probe Configurations
The integral version combines the gauge and probe into a single handheld instrument for convenient routine inspection. Separate-probe versions provide greater flexibility when measuring restricted areas or specialized geometries and are available with standard or metal-reinforced armoured cables for demanding field conditions.
Built for Repeated Surface Profile Inspection
The replaceable tungsten carbide probe tip
Advanced Data Management with Model T
The Elcometer 224 Model T stores up to 150,000 readings in as many as 2,500 alphanumeric batches. Readings can be transferred through USB or Bluetooth® to ElcoMaster® software for analysis, inspection reporting, and traceable project documentation.
Designed for Recognized Surface Profile Standards
The Elcometer 224 can be used in accordance with recognized surface profile inspection procedures including ASTM D4417 Method B, SANS 5772, SSPC PA 17, US Navy NSI 009-32, and US Navy PPI 63101-000.

Frequently Asked Questions
When should I choose the Elcometer 224 instead of Testex® Replica Tape?
The Elcometer 224 is particularly useful when many direct measurements need to be taken quickly because it does not require creating and subsequently measuring individual replicas. Replica tape remains valuable when a permanent physical impression of the tested surface is required for inspection records or when the governing procedure specifically calls for the replica-tape method.
What is the difference between average and maximum peak-to-valley measurement modes?
For each spot measurement, the Elcometer 224 can take a group of 5 or 10 readings. Depending on the selected mode, the reported result can be based on the average of those readings or their maximum value. The appropriate mode should be selected according to the inspection procedure or specification being followed.
Why should several readings be taken at each inspection spot?
Abrasive blasting produces an irregular three-dimensional surface, so a single stylus measurement may not adequately represent the surrounding profile. Multiple readings within a defined area provide a more representative assessment of the prepared surface and reduce the influence of an unusually high or low individual measurement.
Can the Elcometer 224 measure surface profile on pipes?
Yes. Dedicated convex surface profile probes are available for the separate-gauge versions. These probes are designed for convex surfaces and can measure pipes with a minimum diameter of 75mm (3in).
How should the Elcometer 224 be positioned when taking a measurement?
The probe should be positioned at 90° to the substrate. Tilting the probe changes the relationship between the stylus and the surface and can affect the reading, so maintaining perpendicular contact is important for repeatable measurements.
How is the Elcometer 224 checked before an inspection?
The gauge should first be checked and calibrated using the supplied glass zero tile and appropriate calibration foils. Separate Elcometer 224 probes are supplied with a glass zero tile and nominal 125µm (5mil) and 508µm (20mil) calibration foils, together with a test certificate.
When is a separate probe preferable to an integral Elcometer 224?
A separate probe is useful when access, geometry, or operator positioning makes an integral gauge inconvenient. It also allows the use of specialized flat or convex probes and armoured-cable versions for demanding industrial environments.
How does probe-tip wear affect surface profile measurements?
The geometry of the probe tip is fundamental to the measurement, so excessive wear or damage can affect repeatability and accuracy. The Elcometer 224 uses a replaceable tungsten carbide tip designed for up to approximately 20,000 readings, allowing the measurement component to be replaced when required rather than replacing the complete gauge.
How does the Elcometer 224 support SSPC PA 17 inspections?
The gauge can be used for surface profile measurements performed under SSPC PA 17. Its ability to collect multiple readings, calculate statistics, organize measurements into batches, and retain inspection data can simplify documentation when verifying that prepared surfaces meet the profile requirements specified for a coating project.
