The updated procedure is a more reliable <strong>method<\/strong> (<strong>faster and more robust<\/strong>) compared to traditional ones, especially for engine oil analysis, and performs comparably for industrial, mineral and synthetic lubricants (turbine, hydraulic, gear oils, etc). Chemical reactions, reagents and solvents of these two methods are the same, but titration endpoint detection is modified: the new thermometric method uses a highly accuracy temperature sensor for detecting the endothermic reaction of the indicator. The latter has been selected to obtain comparable results to the reference methods, potentiometric ASTM D664 and colorimetric ASTM D974, but using a more reliable technology and not negatively influenced by sludge, insoluble, detergent additives and sample colour. <strong>The results of the new procedure will therefore be equivalent to the historical ones obtained with the previous method<\/strong>,<strong> as established by various correlation studies<\/strong> (see Bibliography), also performed in the Mecoil laboratory on new and used lubricants. So far, it will be possible to<strong> keep the established analytical trends and limits<\/strong>, for an immediate and optimum perception of \u201cconditions monitoring\u201d (lubricants&#8217; and machines&#8217; health state) at your plant.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-8765 aligncenter\" src=\"http:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Grafico-1-300x156.png\" alt=\"\" width=\"615\" height=\"320\" srcset=\"https:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Grafico-1-300x156.png 300w, https:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Grafico-1-768x400.png 768w, https:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Grafico-1.png 875w\" sizes=\"auto, (max-width: 615px) 100vw, 615px\" \/><\/p>\n<figure id=\"attachment_8772\" aria-describedby=\"caption-attachment-8772\" style=\"width: 1070px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-8772 size-full\" src=\"http:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Cattura.jpg\" alt=\"\" width=\"1070\" height=\"300\" srcset=\"https:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Cattura.jpg 1070w, https:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Cattura-300x84.jpg 300w, https:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Cattura-1024x287.jpg 1024w, https:\/\/www.mecoil.net\/wp-content\/uploads\/2019\/12\/Cattura-768x215.jpg 768w\" sizes=\"auto, (max-width: 1070px) 100vw, 1070px\" \/><figcaption id=\"caption-attachment-8772\" class=\"wp-caption-text\">Acidity number: repeatability performance in engine oil analysis<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>Laboratory Manager<br \/>\nAlessandro Paccagnini, CLS MLT-1<\/p>\n<p>&nbsp;<\/p>\n<p>Bibliography:<br \/>\n[1] C.
