HIRANUMA Coulometric Karl Fischer Titrator AQ-2200A

HIRANUMA Coulometric Karl Fischer Titrator AQ-2200A

The AQ-2200A high-end titrator is ideal for the trace level water content determination with its excellent capability and upgraded performance!

Features

Intuitive control panel display!

Current status, data and function keys are displayed on a colorful and large screen. Color touch screen is 7.5-inches wide. All helpful and necessary information is always at hand!

Browse data by PC on a LAN connection!

Result data with curves can be viewed on your PC internet browsing program without optional software.

Enhanced memory data capacity!

Store results data on the USB memory stick and the stored data can be read out on the color display.

-

Built-in thermal printer!

Easy paper loading. High resolution, clear printout.

-

Two KF channels run in parallel!

Combining one additional KF station with either a volumetric or coulometric module enables two different measurements to be performed at the same time. With both a volumetric and coulometric channel, one can measure moisture over the entire range from a few ppm to 100 % or double your sample throughput with 2 identical KF stations.

-
AQ-2200A configured for two-channel capability.
