Technical Specification for KN-6304 Coulometric Karl-Fischer Titration Water Content Tester. Base Configuration: Analytical coulometric titration engine fully compliant with ASTM D6304, ASTM E1064, ASTM D4377, and ASTM D1533 standards for trace water determination in lubricating oils, additives, insulating fluids, and crude petroleum. System Accessories: Supplied with transparent glass electrolytic reaction cell tank, analytical measuring electrodes, cathode chamber assemblies, PTFE ground-joint sealing plugs, straight drying tubes, and a complete set of precision micro-injectors (0.5µl, 50µl, and 1ml variations). Operational Protocol & Maintenance: Demands regular checkups and chemical cleaning of lead pins and socket interfaces using anhydrous ethanol or pure acetone to preserve perfect electrical contact profiles. Cathode Chamber Care: To guarantee zero trace moisture artifact biases, the ceramic filter plate within the cathode chamber assembly must be thermally dried in a dedicated laboratory laboratory oven at 60°C for approximately 4 hours, followed by natural cooling before re-introducing Karl-Fischer reagents.
