Ultra-Sensitive Moisture Analysis with the Trace Moisture Meter DWC-212 (Automatic Karl Fischer Titrator)
Achieve unparalleled accuracy in trace-level water determination with the Trace Moisture Meter DWC-212—a fully automated Karl Fischer (KF) Coulometric Titrator engineered for pharmaceuticals, petrochemicals, specialty chemicals, and battery materials. Capable of detecting moisture from 1 µg to 10 mg H₂O (equivalent to 0.1 ppm to 100%), the DWC-212 delivers laboratory-grade precision for applications where even minute water content impacts product stability, safety, or performance.
Engineered for Precision, Automation, and Compliance
The DWC-212 Trace Moisture Meter uses coulometric Karl Fischer titration, the gold standard for trace moisture analysis, to generate iodine electrochemically and measure water content with exceptional sensitivity. Its sealed, dual-chamber titration cell minimizes atmospheric moisture interference, while the intelligent algorithm automatically detects endpoint stability, calculates results, and validates data integrity—fully compliant with USP <921>, EP 2.5.12, ASTM E1064, and ISO 760.
- Ultra-Low Detection Limit: 1 µg H₂O (0.1 ppm) – Ideal for dry solvents, APIs, lithium salts, and transformer oil.
- Fully Automatic Operation – Auto-titration, drift compensation, endpoint detection, and result calculation.
- Dual-Platinum Electrode System – Ensures stable baseline and rapid response for high repeatability.
- Large Color Touchscreen Interface – Intuitive method setup, real-time titration curve, and GLP-compliant audit trail.
- Data Management & Connectivity – USB, RS232, and optional printer support; exports to CSV or LIMS.
- Integrated Reagent Status & Maintenance Alerts – Monitors anolyte/catholyte life and cell cleanliness.
Trusted in Regulated and High-Stakes Industries
From verifying moisture in lithium battery electrolytes and pharmaceutical excipients to ensuring dryness in high-purity solvents or gas streams, the DWC-212 replaces manual, error-prone methods with a robust, traceable solution. Its compact footprint fits in any QC lab, and its compliance-ready design supports GMP, ISO 17025, and FDA 21 CFR Part 11 documentation requirements.
When water content determines shelf life, reactivity, or safety—precision isn’t optional.
