Karl Fischer Moisture Analyzer
Karl Fischer Moisture Analyzer
The SCD-N is a Karl Fischer titrator engineered to quantify moisture levels across a broad spectrum of substances. It delivers a low detection threshold, straightforward operation, rapid analysis, and consistent reproducibility. The instrument automates the entire measurement sequence, completing stirring and analysis in roughly one minute with results shown directly on screen. A hermetically sealed titration vessel prevents reagent exposure to operators and ambient humidity. It supports trace-level microanalysis, unlimited data storage, and a touchscreen human-machine interface. Stirring speed is programmatically adjusted via on-screen numeric input, and display units (ug, mg/L, ppm, %) switch automatically. Covering a measuring range of 0.0001% (1 ppm) to 100% with a sensitivity threshold of 0.01 μg H₂O, it provides dependable performance.
Features:
1. High-Sensitivity Microanalysis Capability
The instrument is capable of microanalysis of low-content samples with high sensitivity, featuring a sensitive threshold of 0.01μg H₂O and a measuring range from 0.0001% (1ppm) to 100%.
2. Unlimited Storage of Experimental Results
The system allows unlimited storage of experimental results, enabling users to retain comprehensive historical data without capacity constraints for convenient retrieval, comparison, and long-term record keeping.
3. Touch Screen Human-Machine Interactive Interface
A friendly human-machine dialogue and interactive interface with an LCD color touch screen facilitates intuitive operation, allowing users to navigate functions and monitor measurement processes with ease.
4. Program-Controlled Stirring Speed Adjustment
Using program control, users can directly input numbers from the interface to adjust the stirring speed, providing precise control over sample agitation for consistent and reproducible measurement conditions.
5. Multiple Formula Options with Automatic Unit Conversion
A variety of formula options are available, with automatic replacement of display units among μg, mg/L, ppm, and %, streamlining data interpretation across different concentration scales.
