Karl Fischer Coulometric Trace Moisture Analyzer
MT-MC806
Karl Fischer Coulometric Titration Method for water content analysis in liquid, solid, and gaseous samples, covering a range from 0.0001% (1 ppm) to 100%.
Introduction
Our Karl Fischer Coulometric Trace Moisture Analyzer adopts the classic moisture measurement method, the Karl Fischer Coulometric Titration, and can quickly analyze moisture content in liquid, solid, and gas samples within a range of 0.0001% (1ppm) to 100% in just one minute. It can automatically calculate the percentage, ppm mg/L values of moisture content, as well as automatically replace reagents, requiring no manual operation.
Test Principle
Our trace moisture analyzers operate on the Karl Fischer coulometric/volumetric titration method, where iodine reacts quantitatively with water in the presence of sulfur dioxide and a suitable solvent. The amount of iodine consumed is directly proportional to the water content of the sample, enabling accurate moisture determination.
Typical Applications
- Insulating oil and transformer oil
- Lubricating oils and hydraulic oils
- Fuels (diesel, gasoline, kerosene)
- Crude oil and petroleum products
- Chemical solvents and reagents
- Pharmaceuticals and raw materials
Key Features
1. Intelligent Microprocessor Control
This trace moisture analyzer is controlled by an STM microprocessor for precise and automated moisture determination.
2. Large Color Touchscreen Interface
65K color touchscreen (800×600 resolution) displays real-time status and results with intuitive operation.
3. Fully Automated Reagent Handling
Automatic reagent injection and waste disposal prevent operator contact with chemicals.
4. Corrosion-Resistant, Easy-to-Clean Surface
The exterior surface is treated with electrostatic spraying for corrosion resistance and easy cleaning.
5. Automatic Blank Current Compensation
The blank current is automatically compensated by the microprocessor, allowing the reagent to quickly reach a balanced state.
6. High Sensitivity and Fast Analysis
A 430 mA large electrolysis current ensures high detection sensitivity and fast analysis speed.
7. Automatic Data Storage
Measurement results are automatically stored (up to 500 records), and historical data can be accessed at any time.
8. Comprehensive Report Generation
Automatically calculates and prints results, including ug, ppm, percentage content, mg/L, sample name, experiment date, and more.
9. USB/RS232 Connectivity
Supports USB or RS232 interfaces for communication with laptops or computers, enabling network management.
10. Multi-language Display and Upgradeable Program
Multiple language options for operation display, and the instrument’s program can be upgraded when national standards are revised.
