HIRANUMA Automatic Titrator COM-1700A Series

HIRANUMA Automatic Titrator COM-1700A Series

Automatic Titrators designed to meet your needs now and in the future! Our most Intelligent and advanced titrator ever produced, the COM-1700A series.


Color LCD touch panel

Large sized color graphics LCD displays real-time titration curves and differential curves to show reaction tendencies, etc. All information is easily viewed.

Browse results on a PC in a LAN connection

Results data and curves can be displayed on a PC with no optional software.

USB flash memory stick port

The titration results and titration conditions including titration/differential curve data can be stored on a USB JumpDrive. To edit and view the data stored in the USB, an optional software "Titra-Net Viewer" is necessary.

GLP correspondent functions to support reliability of the titration results.

Buret precision test, electrode calibration, reagent remaining volume indication, and other useful functions for maintenance.

Different titrations can run in parallel at the same time.

Up to four titration stations are available.


Password Control and User Authority

Setting password administration allows setting the authority of operation limits for each user. User authority is selected from "Administrator" and "Limited". The one can operate all function and the other can operate limited function.
