Summary

Elcometer 224 Digital Surface Profile Gauge
-
Fast and reliable peak-to-valley surface profile measurement
-
Accurately measure surface profile on flat or curved surfaces up to 500μm (20mils)
-
Measures both average peak-to-valley and average maximum peak-to-valley height
-
Portable, rugged hand-held design is ideal for field use
The Elcometer 224 surface profile meter is available in two different models: Model B and Model T. Each surface profile meter provides the user with increasing functionality - from the entry level Elcometer 224 DModel B Surface Profile Gauge, to the top of the range Elcometer 224 Model T Surface Profile Gauge, with memory, alpha-numeric batching and Bluetooth® communication.
Standard and armoured probes are available for the separate models, providing even greater measurement flexibility. Elcometer surface profile probes are supplied with a glass zero plate, calibration test foils (nominal values 125µm (5.0mils) & 500µm (20mils)) and an Elcometer Test Certificate.

3 Measurement Modes
Whichever test method or Standard you are working to the Elcometer 224 Digital Surface Profile Gauge has a range of easy to use Measurement Modes.
Custom Mode
In Custom mode, simply select to take either 5 or 10 profile readings per measurement then specify either the average, highest or lowest measurement of each set of readings to be displayed and saved into the batch memory4.
Standards Mode
Select the International Standard you are working to and the Elcometer 224 Digital Surface Profile Gauge will automatically set the data collection method accordingly. When selecting ASTM D 4417, you can even choose if the gauge stores the average or highest reading as the measurement.
Immediate Mode
Take individual peak-to-valley measurements and save into the batch memory4. The Elcometer 224 Surface Profile Meter automatically calculates and displays key statistics whilst you’re inspecting, and you can set limits so the gauge will alarm whenever the reading is outside a predefined acceptable range.
How to Measure Surface Profile

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.
Wireless Connectivity

Instantly transfer readings, statistics, and limits; via USB or Bluetooth®; to your PC or mobile device, using ElcoMaster® or your own software application, creating professional inspection reports in minutes.
Fast, accurate and very user friendly, the Elcometer 224 Surface Profile Gauge is available with or without memory and Bluetooth®.
