Overview
The HI933-02 Karl Fischer volumetric moisture meter is an automated volumetric method with High Accuracy, High Flexibility, and Repeability Karl Fischer Titrator. The Titrator is designed to perform titration for a variety of applications, allowing users to obtain good results and high-speed analysis. The HI933 can analyze water content in the range of 100 ppm to 100%, automatically dispense the titrant, detect endpoints, and perform all necessary calculations and plotting.
Features
1. Small footprint, requires minimal workbench space
2. The shell is made of strong, chemical corrosion resistant plastic
3. Powerful built-in algorithms for termination criteria based on fixed mV endpoints or absolute/relative drift
4. Sample analysis averages and statistics Minimize water vapor ingress with a sealing solvent system
5. Balancing interface for automatic weighing
6. Supports 100 titration methods
7. User-defined reports
8. Clear display of warnings and error messages
Principle
The HI933-02 uses the Karl Fischer volumetric method for moisture determination, which completes moisture analysis by automatically dispensing titrant and detecting endpoints. The instrument has powerful algorithms built into the instrument to determine termination criteria based on fixed mV endpoints or absolute/relative drift, while minimizing water vapor entry through a sealing solvent system to ensure measurement accuracy.
Applications
Moisture determination of liquid or solid samples
Standards
Karl Fischer Volume Method Standard
Steps
