but also the highest and lowest coating thickness values over the entire scan.


Each set of three readings is then stored into memory, together with the date and time of the scan. The values can also be displayed on the gauge’s display as a run chart.


During each scan, the Elcometer 456 displays the live thickness reading – together with an analogue bar graph which graphically indicates the thickness relative to both the nominal thickness and any user defined thickness limits.


Put simply, the user can now just ‘drag’ the probe continuously across a coated item and, upon removing the probe from the surface, at a glance, see on the display the average, highest and lowest readings, as well as whether they are inside or outside any pre-determined limits - thus providing invaluable and immediate information.


The Scan Mode can also be used with a ‘hold’ function. This feature allows the probe to be momentarily lifted from the surface to clear areas such as welded joints

or cut outs and then placed back in contact with the coating to continue data recording without interruption of the data set.


Auto Repeat Mode


In Auto Repeat Mode, as the probe slides across the surface individual readings are stored in the memory of the gauge at a rate in excess of 140 readings per minute thereby significantly speeding up the inspection of large areas of coatings which require the recording and analysis of individual film thickness values.


Working with Standard Test Methods


International Standard Test Methods often describe the number of individual gauge readings to be taken in a spot measurement and/or the number of spot measurements required over a defined surface area.


SSPC PA2, for example, requires a minimum of three gauge readings to be taken per spot measurement and five spot measurements over a 10 m² area. Using the Elcometer 456’s Counted Average and Fixed Batch modes with the Ultra/Scan probe set to Auto Repeat, the gauge automatically takes 3 readings, stores the average and is then ready for the next set of three measurements.


In this way, the user no longer has to lift the probe off the surface in between each gauge reading – reducing the time it takes to measure according to SSPC PA2 (or similar test methods) by up to 40%.
