SFK-503V Karl Fischer Titrator (Volumetric Method)

Overview
The SFK-503V Karl Fischer Titrator (Volumetric Method) supports automatic measurement mode, KF titer determination mode, automatic Karl Fischer oven measurement, and Karl Fischer oven blank mode, meeting the moisture measurement needs of different types of samples.

The solvent manager adopts anti-leakage and anti-suck-back designs for the waste liquid bottle. It supports titration cup liquid filling, titration cup liquid draining, titrant mixing, and automatic cleaning functions. This effectively prevents direct contact with KF reagents, ensuring the safety of operators and the environment during measurement and use.
