The&nbsp;<b>dynamic contact angle measuring instruments</b>&nbsp;and<b>&nbsp;tensiometers</b>&nbsp;of the DCAT series&nbsp;are based on the latest balance technologies developed by the company Sartorius AG, Germany. The monolith balance systems used by our instruments operate on the principle of electro dynamic compensation, to combine the maximum precision with the greatest possible stability. The DCAT measuring instruments are fitted with 100 g reference masses of class E2 (Ã±0.15 mg) as specified under R111 of the International Organization of Legal Metrology (OIML).Monolith precision balance module

This ensures that all&nbsp;<b>tensiometer</b>readings comply with national and international standards, for example:
<ul><li>ISO 6295 Determination of interfacial tension of oil against water.</li><li>ISO 6889 Surface active agents -<strong>determination of interfacial tension</strong>by drawing up liquid films.</li><li>ASTM D971-99a<strong>&nbsp;Standard test method for interfacial tension</strong>&nbsp;of oil against water by the ring method.</li><li>ASTM D1417-03a Standard method of testing rubber latices - synthetic.</li><li>DIN EN 14210 Surface active substances&nbsp; (<strong>Determination of interfacial tension of surface active solutions by frame and ring method</strong>).</li></ul>
