ELCOMETER The Ultra/Scan Probe with replaceable end caps for increased durability Memory capacity of up to 150,000 readings in up to 2,500 individual batches with alphanumeric identification, interchangeable probes and output to ElcoMaster ® software, makes the Elcometer 456 very powerful. Measurement accuracy capability to ±1% on smooth, rough, thin and curved surfaces the Elcometer 456 gives you repeatable and reproducible results. It comes with a 2-year gauge warranty. Incredibly fast measuring speed of more than 70 readings per minute (140+ readings per minute with the Ultra/Scan probes) – the Elcometer 456 is more than 40% faster than other gauges. The Elcometer 456 is supplied complete with the ElcoMaster ® software which provides simple and efficient data management for a range of coating inspection instruments. ElcoMaster® can also be downloaded free of charge from the Elcometer website. The Ultra/Scan Probes come fitted with a ‘snap on’ replaceable plastic end cap so that the sliding action required to carry out a scan of the whole coated surface does not cause any wear to the probe tip. This is crucial to maintaining the accuracy of the probe over its working life. The Ultra Scan probes use the Elcometer 456’s patented offset feature, ensuring that the thickness of the cap is included in the calibration adjustment process and discounted from the thickness readings. It should be noted that the ranges quoted above are reduced by the thickness of the protective cap which is approximately 250 µm. As the cap wears during use, this effect on the thickness readings is also taken into account. The gauge will display a warning message when the degree of wear requires the cap to be replaced. The firmware for the Elcometer 456 Separate gauge, Top (T), has been enhanced to allow the Ultra/Scan probe to be used and to operate in either the Scan Mode or the Auto Repeat Mode. In Scan Mode the probe can slide over the surface of the coating. As the probe is lifted, the gauge displays the average coating thickness value for the area, the highest thickness value and the lowest thickness value. Each set of readings, generated when the probe is lifted, can be displayed (average, high and low) on the run chart and stored in the memory of the gauge. In Auto Repeat Mode a reading is taken approximately every half second as the probe slides across the surface, with each individual reading stored in the memory of the gauge. With a reading rate in excess of 140 readings per minute; the Auto Repeat Mode will significantly speed up the testing of large areas of coating. 148 2020 - 2021 read online: www.surfaceworld.com
