Automatic Karl Fischer Moisture Analyzer, KFMA-310S
Description
The trace moisture analyzer adopts a 7-inch capacitive high-definition color touch screen, the interface is simple and intuitive, and the operation is simple and fast. The unique circuit and program design has the advantages of high test accuracy, fast electrolysis speed, short equilibration time, accurate blank subtraction, and accurate and reliable analysis results.
Strong environmental adaptability & high measurement accuracy
- The all-digital intelligent control measurement of the electrolytic measurement process accurately deducts the background current and completely eliminates the influence of ambient air humidity and stirring rate;
- Exclusive use of real-time dynamic impedance method to determine the titration end point, the measurement results are more accurate;
- Equilibrium point (titration end point) can be set, which ensures the wide adaptability of the instrument to reagents of different sensitivity
Multiple built-in test methods, easier to test
- Elaborately refined eight concentration calculation formulas, covering most of the moisture measurement standards at home and abroad;Six test methods are optional to meet various needs;
- It can store 496 sets of measurement data, and its own printer can query and print in real time
High reliability
- The core device adopts American industrial grade data conversion chip, which has excellent linearity and long-term stability;
- The components and key components used are all international first-line brands
Easy to use
- Navigation menu design, functions are clear at a glance, capacitive touch screen operation, simple and fast operation.
Rich display content, the measurement process is clear at a glance
- Simultaneously online display of water content, measurement time, PPM, percentage content, electrolysis current, potential, system time. The experimental process is clear at a glance, and problems can be found in time;
A variety of test result units are available, suitable for different samples
- Automatic calculation of measurement results, including percentage, ppm, mg, etc.;
