To measure without removing the paint you need Echo-Echo mode, available on the ZX6-DL.  <\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1757700001000\"><strong class=\"schema-faq-question\">Can I save the measurements?<\/strong> <p class=\"schema-faq-answer\">No, the ZX-1 has no data logger: readings must be written down manually. If you need to archive the data, you need a DL model such as the ZX6-DL. <\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1757700002000\"><strong class=\"schema-faq-question\">What does fixed velocity mean?<\/strong> <p class=\"schema-faq-answer\">That calibration is carried out by selecting the material&#8217;s propagation velocity from a list, instead of performing a calibration on reference blocks. The velocity nevertheless remains adjustable to suit different alloys. <\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1757700003000\"><strong class=\"schema-faq-question\">Is a training course needed to use it?<\/strong> <p class=\"schema-faq-answer\">No. The manufacturer presents it as an instrument that requires no specialist training. The general principle of non-destructive testing still applies: the reliability of the measurement depends on surface preparation and on the choice of probe.  <\/p> <\/div> <\/div>\n\n<p class=\"ndt-torna-su wp-block-paragraph\"><a href=\"#indice\">\u2191 Back to index<\/a><\/p>\n\n<p class=\"wp-block-paragraph\">For a quotation or for help choosing the probe best suited to your application, <a href=\"https:\/\/ultrasuonindt.it\/en\/contact\/\">contact our technical department<\/a>.<\/p>\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h5 class=\"wp-block-heading\">Further information and contacts <\/h5>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><a href=\"http:\/\/www.roder.it\">Systems division and sensor integration partner : www.roder.it<\/a><br\/><a href=\"https:\/\/ultrasuonindt.it\/chi-siamo\/\">More information about RODER SRL : about us<\/a><br\/>Contact for general information : <a href=\"mailto:info@roder.it\">info@roder.it<\/a><br\/>Contact for information about these products : <a href=\"mailto:info@roder.it\">info@roder.it<\/a><\/p>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><br\/>The information contained on this web page is provided for information purposes only.
