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

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.
