<h2>Dynamic Contact Angle Meter and Tensiometer for molten metals and salts.</h2>
<h1><p style="font-size: 12px; font-weight: normal; ">The system is used to study the performance of zinc/aluminium treatment processes on steel surfaces and the action of ionic salts on different metals. Also the wetting properties and the reaction to chemical treatment of high temperature solders, can be investigated in detail by the VZSIM/DCAT.</p><p style="font-size: 12px; font-weight: normal; "><strong>The VZSIM/DCAT is used for the software controlled determination of:</strong></p><ul style="font-size: 12px; font-weight: normal; "><li>the temperature and time dependant contact angle of molten metals and salts, under vacuum or inert/reducing gases, with optional sample pre-heating (for zinc/aluminium treatment).</li><li>the dynamic contact angle of prismatic and cylindrical samples according to the Wilhelmy method.</li><li>the static, time and temperature dependant surface tension of molten metals and salts up to 600 Ã°C.</li></ul><p style="font-size: 12px; font-weight: normal; ">&nbsp;<br /><strong>The VZSIM/DCAT consists of the basic instrument with the following technical equipment:</strong></p><ul style="font-size: 12px; font-weight: normal; "><li>Stable metal base frame with floor levelling.</li><li>High-precision, electro-dynamically compensated weighing system with automatic calibration function.</li><li>Software controlled motorised height positioning of the sample and the smelter vessel with variable speeds.</li><li>Integrated measuring and control electronics for powerful and fast heat generation.</li><li>Online display for weighing data, temperature and other measuring parameters in the software.&nbsp;</li><li>Serial RS 232C interface with PC connection cable.&nbsp;</li><li>Infrared radiation based, software controlled pre-heating system for metallic samples with outer quartz glass walls and upper and lower cooling flanges (water based).&nbsp;</li><li>Vacuum system with several valves for complete or partial sample space evacuation.&nbsp;</li><li>Several thermo couple sensors with integrated signal conversion electronics.&nbsp;</li><li>Special chuck with low thermal conduction for metal or ceramics samples.</li><li>Built in slag remover for the smelter.</li></ul></h1>
