KFT-50VC Karl Fischer Titrator

KFT-50VC Karl Fischer Titrator — Precision Water Content Testing The KFT-50VC Karl Fischer Titrator is a benchtop instrument supporting both Volumetric and Coulometric Karl Fischer titration for water content determination, using the Karl Fischer chemical titration method — a different testing principle from loss-on-drying/halogen moisture analyzers such as the HQ Series. Dual Titration Modes Supports both Volumetric and Coulometric Karl Fischer titration in a single unit, covering a moisture range from 3.0 μg to 250.0 mg depending on mode. An integrated oven sampling method extends testing to gas, solid, and liquid samples. Features CE Certified 7.0" color touchscreen: high-contrast LCD for intuitive operation Dual titration principle: Volumetric KF (100 μg – 250.0 mg range) and Coulometric KF (3.0 μg – 200 mg range) on one instrument Oven sampling method: for constant-moisture and trace-moisture measurement of gas, solid, and liquid samples Intelligent operation system: user management, method management, sensor management, titrant management, and data management Safe solvent handling: anti-leakage, anti-pour waste-liquid-bottle design for titrant fill/drain, solvent feed, titrant mixing, and burette cleaning Auto/manual drift adjustment for accurate results across selectable units (μg, mg, %, ppm, mg/L, μg/mL) Data management: stores up to 2,000 titration data sets (GLP-compliant), with RS-232, USB, and U-disk (CSV/PDF) export Specifications Volumetric KF — Range: 100 μg – 250.0 mg (Resolution 1 μg, Repeatability ≤0.3%) Coulometric KF — Range: 3.0 μg – 200 mg (Resolution 0.1 μg, Repeatability ≤0.3%) Units: μg, mg, %, ppm, mg/L, μg/mL mV Range / Resolution: 0–2000 mV / 0.1 mV Polarization Current Range: 1–200 μA (±3% accuracy, ±2.5%/30min fluctuation) Working Current (Coulometric only): ±0.5% accuracy, ±0.2%/10min fluctuation Power Supply: 100–240 VAC, 47–63 Hz Dimensions: 240 × 370 × 270 mm Net Weight: ~4 kg Frequently Asked Questions Q: What is the difference between the KFT-50VC and the HQ Series moisture analyzer? A: They use different testing principles. The HQ Series uses halogen heating / loss-on-drying (gravimetric method), while the KFT-50VC uses Karl Fischer chemical titration, supporting both Volumetric (100 μg – 250.0 mg range) and Coulometric (3.0 μg – 200 mg range) modes. Contact us to discuss which method fits your application. Q: What's the difference between Volumetric and Coulometric titration on this instrument? A: Volumetric KF titration covers a higher range (100 μg – 250.0 mg), suited to samples with higher water content. Coulometric KF titration covers a lower, more sensitive range (3.0 μg – 200 mg), suited to trace-moisture testing. The KFT-50VC supports both on one unit. Contact us for method selection guidance. Q: What sample types can the KFT-50VC test? A: Using its oven sampling method, it can test gas, solid, and liquid samples for constant or trace moisture content. Contact us to discuss your specific sample type. Q: How much data can the KFT-50VC store, and how do I export it? A: Up to 2,000 titration data sets (GLP-compliant), exportable via RS-232 print, USB to PC software, or U-disk as CSV or PDF. Contact us for integration with your data systems.
