Introduction
This Manual Karl Fischer Moisture Meter is based on the classic Karl Fischer coulometric titration method and is designed for reliable determination of moisture content in liquid, solid, and gas samples. The instrument is capable of fast analysis within one minute, covering a wide moisture range from 0.0001% (1 ppm) to 100%.
With stable microprocessor control and a clear digital display, this model offers a cost‑effective and dependable solution for routine moisture testing. It is widely used in chemical processing, petroleum products, electric power, scientific research, railway systems, and industrial quality control laboratories.
Typical Applications
- Petroleum products and lubricants
- Chemical raw materials and intermediates
- Insulating oils and power industry samples
- Laboratory research and teaching
- Industrial process and quality control
Key Features
1. Microprocessor-Controlled Operation
Intelligent microprocessor control ensures stable titration performance with a sensitivity of 0.1 μg.
2. Sealed Titration Cell Design
A fully sealed titration cell prevents direct contact with Karl Fischer reagents and minimizes the influence of ambient humidity on test results.
3. Automatic Drift Compensation
Blank current is automatically compensated by the microprocessor, allowing the reagent to reach equilibrium quickly and improving measurement reliability.
4. Adjustable Stirring Speed & Self-Diagnosis
Electronic key control enables adjustable stirring speed, while the built‑in self‑diagnosis function helps identify system faults efficiently.
5. High Electrolysis Current for Fast Response
Automatic control of electrolysis current up to 400 mA significantly enhances sensitivity, accuracy, and analysis speed.

Why Choose US – Manual Karl Fischer Moisture Meter
Cost-Effective Solution for Routine Testing
Compared with fully automatic Karl Fischer moisture analyzers, this manual digital model provides the same reliable coulometric principle at a more economical investment level. It is ideal for laboratories that require accurate trace moisture determination without advanced automation features.
Reliable Core Technology
Built on the proven Karl Fischer coulometric titration method, the instrument delivers stable and repeatable results across a wide moisture range (ppm to percentage levels). Automatic drift compensation and controlled electrolysis current ensure dependable performance in daily operation.
Simple Operation & Easy Maintenance
The six-digit digital display and key-controlled interface make operation straightforward for laboratory technicians. With fewer complex components than fully automatic systems, maintenance is simplified and long-term service costs are reduced.
Compact & Laboratory-Friendly Design
The sealed titration cell minimizes environmental humidity interference while protecting operators from reagent exposure. Its compact structure (300 × 250 × 100 mm) makes it suitable for laboratories with limited bench space.
Ideal for Standard Quality Control Environments
For industrial QC labs, educational institutions, and facilities where automated data networking is not required, this manual Karl Fischer moisture analyzer offers an excellent balance of accuracy, stability, and affordability.
