The AT-710 Automatic Potentiometric Titrator Series, is a powerful instrument that can accommodate 2 burette drives, allowing operators to run 2 different methods without swapping burettes, the Burette drive unit is designed to be more compact than before and can be installed in A4 size. Each burette drive has quick swap-out burettes for even greater flexibility. The piston head is improved, so the design means that air bubbles are not produced so much. It can upgrade to an advanced model. All AT-710 series titrators have a propeller stirrer configuration but can be easily switched to a magnetic stirrer. Although referred to as the “basic” model, the AT-710B has a software CD that operators can use to create, edit, and save methods on their computers. Methods can be transferred to the titrator or data from the titrator to a laptop with a USB thumb drive. Sample changer (CHA-700) (option) can be connected. A sample changer of compact 6 or 11 samples can be connected and used for multiple sample measurements. As an option, a keyboard for entering numbers and a barcode reader for setting the sample that allows the user to start measuring without touching a device are installed.
