Automatic Potentiometric Titrator DKK-TOA AUT-701

Manufacturer: DKK-TOA
Model: AUT-701

Product Features:

Dual Titration System: Easily upgradeable to a dual titration system by adding an additional automatic buret and accompanying accessories. Allows simultaneous titration of multiple samples when connected to the TTT-710 sample turntable.
Expandable Titration Methods: Supports up to 4 electrodes and 10 burets. Can add electrodes such as Photometric, Polarization, and conductivity to expand the titration methods.
Equipment Validation Support: Records the history of 20 pH calibrations, checks buret volume history, and monitors environmental conditions when additional temperature and humidity sensors are connected.
USB and LAN Connectivity: Machine data can be saved in CSV format, facilitating easy management and transfer to other software.
