ASTM D6304 E1064 Karl Fischer Moisture Meter ISO 10337 Karl Fischer Micro Moisture Analyzer
Introduction
The Karl Fischer micro moisture analyzer is automatically controlled by a single-chip microcomputer. It has self-diagnosis for system failures, a color liquid crystal touch screen, a full Chinese menu, and a more user-friendly interface. It automatically subtracts the blank current, has high accuracy in test results, a large current background compensation function, significantly shortened standby time, a unique reagent failure detection function, and automatically reminds users to replace the failed reagents in time, thereby greatly improving the utilization rate of the reagents. It has built-in multiple calculation formulas for moisture content, which meets the needs of different users.
