LCD Display Adjustable in 16 Positions

Each user can adjust the angle to their liking. The position can be locked so that it will not move when the screen is pressed

Two Types of Titration in Parallel

Add a titration station and stirrer to carry out two types of titration in parallel.

USB/LAN Port

Approximately 9,900 results can be stored on a USB memory stick. With optional software, you can view the data on a PC or use a recalculation function. With a LAN connection, you can also view the data on a Web browser.

User Authentication Settings

User restrictions can be imposed for improved security as well as the prevention of inadvertent changes to, for example, measurement conditions.

Status Indicator with 3 LED Colors

Colored lights allow you to confirm the status of operation from a distance. You will also be alerted to unexpected problems right away.

Easy Burette Head Replacement

Simply slide toward you to remove. Can be replaced, together with the reagent bottle, using just one hand. With multiple buret heads, you can quickly manage different titrants simply by switching them.

Economical Purge Function

Repeat discharging/charging at the top end of the syringe. Reagents can be replaced automatically, which greatly reduces waste fluid. The number of economical purge cycles can be set from 1 to 99.

Forty Rotation Speeds Can Be Set

Rotation can be adjusted manually in fine increments shown by LED bars—it is easy to see and understand. (Four increments per bar)
