Coulometric Karl Fischer Titrator LWT-A31 Catalog

Overview

Coulometric Karl Fischer Titrator LWT-A31 is a benchtop unit with 5 to 40°C ambient temperature range, 3 µg to 9999.9 µg measurement range, and offers 400 mA maximum current. Excellent low-power operation makes it possible to compact battery, enables portable function criterion for measuring electrode signal for the electrolysis end. It stability and accuracy are key factors affecting the measurement accuracy. Designed with streamline and 5 inch coloured touch screen with standard testing method used ASTMD4928, ASTMD1533 and ASTMD6304 in titration process.
