1. Introduction

1-1. Overview of the instrument

We thank you for your continued patronage of KEM products. The AT-610 Automatic Potentiometric

Titrator you have purchased is the latest titration system to determine concentration of target substance in

liquids or solids, operated easily and resulting quickly with high precision and accuracy. By changing the

electrode and preamplifier, those titrations like acid base, redox and photometric can be equally performed

as well.

[Features]

1) Two (2) measuring units can be connected (simultaneous measurements in parallel)

Addition of another AT-610 as option to this unit allows you to make two measurements

simultaneously. In addition, this unit can be also used in combination with MKA-610 (Volumetric

KF titrator) or MKC-610 (Coulometric KF titrator).

2) A Large color LCD with two languages selective on display

A large 8-inch color LCD provides easy view and operation with language selection of either English

or Japanese on display.

3) Real time titration curve and two potentials are displayed and recorded simultaneously

Titration in progress can be seen in real time, and two potentials of titration and temperature, pH and

transmittance as well as pH and conductivity can now be recorded at the same time, which used to be

unavailable with the existing titration devices. Measurement of transmittance or conductivity requires

optional parts.

4) Operating panel is Touch-on type LCD

You just touch on the display panel following the guiding messages to complete a series of

measurements. The panel is covered with a protection film which is replaceable with a new one

whenever you want a better view in the course of time.

5) Operating unit and measuring unit can be separated

The measuring unit can be detached depending on sample type when so necessary.

6) Data Storage on Compact Flash (CF) Card:

Allow an operator to store Measuring conditions (Method Parameter) and Titration results on CF cards

(option).

7) GLP/GMP conformed

Up to 50 operators names can be registered. Also, check results with standard substances and

calibration records for electrodes can be recorded. Recorded results can be displayed as history.

Further, AT-610 features reminders of the day for replacing reagent and piston.

8) Platinum thermal resistor Pt100 sensor ensures precise measurement of temperature

Pt100 platinum resistance element is quipped for sensing correct measuring temperature.
