## Description

The KF-51 is Nittoseiko Analytech's new compact coulometric KF titrator (launched in 2025). It replaces the classic CA/KF series and provides the same measurement performance in a smaller format with a touchscreen and modern data connectivity.

The platform integrates with Nittoseiko's evaporator EV-2000 for indirect water analysis of samples that cannot be introduced directly, such as petroleum, polymers and hygroscopic solid samples.
