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.
