The Metrohm 899 Coulometer is a compact, high-precision instrument designed for trace-level water content analysis in liquids, solids, and gases. Despite its small footprint, it integrates a powerful coulometric system with an internal magnetic stirrer, making it ideal for labs where space is limited. The system includes both an indicator and generator electrode (without diaphragm) and supports a recommended measuring range of 10 µg to 200 mg of water, eliminating the need for titer determination due to its absolute measurement method. The intuitive Ipol measuring mode, precise temperature monitoring, and user-friendly interface make the 899 Coulometer a dependable tool for consistent and accurate moisture determination.
