The Master Science KF Moisture Titrator is a compact, budget-friendly Karl Fischer instrument offered as a volumetric model for higher water contents or a coulometric model for trace moisture. Both share a 7-inch high-contrast touchscreen, solvent manager and automatic drift correction.
Oven sampling is supported on both versions, extending measurement to solids, gases and samples that release water slowly.

Key Benefits
- Choose the right technique: the Master Science KF Moisture Titrator comes in volumetric and coulometric versions to suit your water range.
- Safe reagent handling: the solvent manager drains and refills reagents in a closed system.
- Stable endpoints: automatic or manual drift correction compensates for ambient moisture.
- Fits small labs: a compact footprint and simple touchscreen operation.
- Easy data export: results go to a printer, PC or U-disk.
Labs that need both KF techniques in one unit can choose the Master Science dual-mode Karl Fischer titrator.

Common Laboratory Problems and How This Titrator Helps
How the Master Science KF Moisture Titrator supports routine water testing:
- Loss on drying is too slow and unspecific: KF titration measures water directly.
- Reagent exposure: closed solvent handling limits contact.
- Unstable results in humid labs: drift correction compensates automatically.
- Hard-to-dissolve samples: oven sampling is supported.
- Manual result recording: USB and printer output document each run.
