Automatic titrator AT-700

The Kyoto Electronics KEM automatic titrator AT-700 is a common analytical instrument designed based on the principle of potentiometry for volumetric analysis.
The principle of potentiometry is to select appropriate indicator and reference electrodes to form a working battery with the measured solution. With the addition of titrant, the concentration of the measured ion continuously changes due to chemical reactions, resulting in a change in the potential of the indicator electrode. Near the endpoint of titration, there is a sudden change in the concentration of the measured ion, causing a jump in electrode potential. Therefore, the endpoint of titration can be determined based on the jump in electrode potential.

Main features of automatic titrator AT-700:

1. Simple and exquisite design: The driving part of the burette has a compact structure with a propeller mixing method, occupying an A4 size area.
2. High precision burette: The accuracy of the 20mL burette is ± 0.01mL (10 μ L), and the liquid filling resolution of the burette is 1/20000.
3. Diversified serial interfaces: Standard RS-232C interface, USB serial port, and SS-BSU connection port, plug and play.
4. Method editing software: Experimental methods and parameters can be created on a computer, directly transmitted to the host for storage and execution.
5. Expansion of titration unit: Standard configuration includes 1 set of liquid addition unit, which can be expanded to 2 sets on the host, and 8 sets of liquid addition devices can be externally connected.
6. Operation and connection functions: including multiple conversational languages including Chinese, and can also connect to an integrated multi sample injector.
