The Probe Range


Elcometer surface profile probes are fitted with a tungsten carbide user replaceable tip as standard, suitable for up to 20,000 readings.

Probes have a measurement range of 0 - 500µm (0 – 20mils) and are accurate to ±5% or ±5μm (±0.2mil).

Probe Range

Index

Elcometer 224 Separate Gauges and Probes are ideal for measuring in awkward or confined spaces.


Elcometer 224 Separate Probes are available with a standard cable or armoured, reinforced heavy duty cable.

Probe Range

Index

The armoured cable is ideal for measuring in harsh environments and offers added protection against snagging and impact damage.

Each probe is supplied with calibration test foils, probe protection cap and test certificate.

Calibrating the Gauge

Verifying the Gauge Calibrationand Accuracy


Calibrating the gauge is the process of zeroing on a smooth glass “zero” tile.

The new Elcometer 224 has on screen instructions to guide the user through the calibration process.


IndexAfter continued use, the surface of the glass “zero” tile will begin to wear. If a repeatable zero cannot be obtained the tile should be replaced.


If no zero tile is available, the “Factory Calibration” option can be used.

This returns the gauge to the calibration set up during manufacture and test using reference probes but is not as accurate as a gauge calibration.


Index


The calibration and accuracy of the gauge can be verified at any time using foils and a glass zero tile - without affecting any statistics or batch memory.

Simply select “Test Calibration”, follow the on screen instructions and compare the reading value displayed with the glass “zero” or measured foil value.

Verifying the Gauge Calibration & Accuracy

IndexAfter continued use, the surface of the glass “zero” tile will begin to wear. If a repeatable zero cannot be obtained the tile should be replaced.


The Elcometer 224 precision manufacturedprobe tip will wear over time from a sharppoint to a flattened or rounded point.

This reduces the accuracy of the gauge as the tip cannot reach the trough of the profile.

Tip wear and gauge performance can also be assessed by using the “Test Calibration” function.

Verifying the Gauge Calibration & Accuracy

Index


The Elcometer 224 probe tip is a consumable item with can be replacedby the user.

A 2-point factory recalibration is required after a tip replacement to ensure the continued accuracy of the gauge.

Comparing the Elcometer 224’s


The new Elcometer 224 follows the same menu structure as the Elcometer 456 Coating Thickness Gauge with “Cal”, “Batch”, “Stats” and “Menu” softkeys.

The new Elcometer 224 significantly improves the product features of the existing gauge and has many of the new Elcometer 456 features.

Features in the new Elcometer 224 not in the old model include:

Additional Statistical functions: Coefficient of Variation High & Low Limits Number Above and Below Limits


The Elcometer 224 can have user defined Upper and Lower limits for each batch.

If a reading is outside set limits;

the red LED illuminates; the alarm sounds; the display reading turns red; the relevant limit icon goes red

When limits are set; the gauge also displays the number of readings that are above or below the pre-defined limits.

When using Testex® Tape, the replica tape measures the surface profile over a 70.89mm² area – the area of the memory foam. It measures the maximum peak-to-valley height within the test area.

Index

Counted Average Mode

In order to establish the surface profile using an Elcometer 224, a number of readings over an area are required to generate an average profile.

The average of the individual readings provides the user with the average peak-to-valley height over the measurement area.


The “Counted Average” feature on the new Elcometer 224 is a very useful technique for assessing an area of profile.

To establish the average surface profile, between 5 and 10 readings should be taken within a 150 x 150mm (6 x 6”) area.

The average of these individual spot measurements provides the user with the peak-to-valley height over the measurement area.

The Counted Average mode allows the average of the spot readings to be recorded into memory automatically.

The user can view a line trend graph of the last 20 measurements, which is updated automatically when each reading is taken.

Why choose the Elcometer 224?

How does it compare with other test methods?


Two other methods commonly used for measuring surface profile are:

Surface Comparators; Replica Tape & Micrometer

Thickness Gauge

Surface Profile Test Methods

Index



Index

Surface ComparatorsStandard surface comparators are available as eithergrit, shot or sand and are used to compare freshlyblasted profiles to pre-defined profiles.

Whilst surface comparators provide a useful indication of surface profile, it is a subjective test.

As they rely on visual comparison, the interpretation of the profile is dependent on the user.



Index

Replica Tape & Micrometer Thickness GaugeReplica Tape produces a numerical value for the profileand has the added advantage of providing a ‘proof oftest’ as the tape can be included in manual reports(if stored correctly).

The foam side of the tape is rubbed into the surface, providing a permanent mould of the peak-to-valley profile which can then be measured using a micrometer thickness gauge.



Index

The tape is available in four ranges for different profile ranges;

Coarse minus (C-) (not used in blast profiles) Coarse (C) for 20-38μm (0.8-1.5mils) profiles X-Coarse (XC) 64-115μm (2.5-4.5mils), X-Coarse plus (XC+) for profiles between 115-127μm (4.5-5.0mils)

Due to recent changes in the technical specification, in some cases, more than one test has to be undertaken with different grades of tape.

0.5 0.8 1.5 2.5 4.5 5.0 mils

12 20 38 64 115 127 µm

C- XC+Coarse (C) (C+XC)/2 X-Coarse (XC)


If a measurement is made with Coarse grade tape which is greater than 38μm(1.5 mils), a second measurement must be taken at the same spot with the X-Coarse grade.

If BOTH readings are between 38-64μm (1.5–2.5mils), the average of the two measurements should be taken as the surface profile.

If the reading taken with the X-Coarse grade tape is between 38-64μm (1.5–2.5mils) then a second measurement must be taken with the Coarse grade at the same spot, and the average recorded as the surface profile.

Finally, if the measurement taken with the X-Coarse grade is above 64μm (2.5mils), then this single measurement should be recorded as the surface profile at this spot. In this case the measurement taken with the Coarse grade should be discarded.

It is important to note that in this case, both tape grades must be in the inspector’s toolkit as simply taking one grade will not be sufficient to record an accurate profile measurement.

0.5 0.8 1.5 2.5 4.5 5.0 mils

12 20 38 64 115 127 µm

C- XC+Coarse (C) (C+XC)/2 X-Coarse (XC)


Index



Index

The measurement of the replica tape is taken with a a micrometer thickness gauge. Care should be takento subtract the original thickness of the tape windowfrom the total thickness of the tape and rubbed profile.

Additional consideration should be taken when selecting an appropriate micrometer – not only to ensure the appropriate scale on the dial, but also the appropriate force and anvil area (hence pressure) is applied to the tape – avoiding crushing the replica.



Index

As can be seen, this apparently simple and fast test is fraught with potential errors to untrained inspectors. It is further complicated by the fact that earlier versions of the replica tape did not require the averaging procedure.

For some inspectors, this information will have been overlooked. For those inspectors with stockpiles of old versions of tape, care should be made to ensure that the type of tape is clearly identified on the record worksheet.



Index

To accurately assess a surface profile, and obtain digital records for reporting purposes, the use of a digital surface profile gauge, such as the new Elcometer 224, is recommended.
