The Master Science Karl Fischer Moisture Analyzer is designed for regulated laboratories that need traceable water content results. It is available as a volumetric model for samples from 100 µg to 250 mg of water, or as a coulometric model for trace levels from 3 µg.
Both versions offer three-level user management, method, sensor and titrant management, GMP logging and storage of 2000 GLP-compliant results, together with oven sampling for difficult matrices.

Key Benefits
- Traceable results: the Master Science Karl Fischer Moisture Analyzer records every change in GMP logs with three user levels.
- High repeatability: ≤ 0.3 % RSD on both volumetric and coulometric versions.
- Large GLP memory: 2000 titration results are stored for review and export.
- Complete peripheral support: printer, barcode reader, balance and oven connect directly.
- Safe reagent management: a closed solvent manager handles KF chemicals.
Compare with the Master Science compact KF moisture titrator for smaller laboratories.

Common Laboratory Problems and How This Analyzer Helps
How the Master Science Karl Fischer Moisture Analyzer supports regulated moisture testing:
- Incomplete audit trails: GMP logs track users and changes.
- Transcription errors: balance and barcode inputs feed data directly.
- Variable trace moisture results: coulometric detection with ≤ 0.3 % RSD.
- Reagent handling risk: the solvent manager keeps chemicals enclosed.
- Solids that will not dissolve: oven methods transfer water as vapour.
