Features
Large Color LCD Touch PanelA large 8.4″ touch panel screen enables the user to input text easily. Selecting functions from the menu can be operated intuitively. The protective film can be replaced to protect it from scratches and wear over the long term. |
 |
LCD Display Adjustable in 16 PositionsEach user can adjust the angle as he/she likes. The position can be locked so that it will not move when the screen is pressed. |
 |
Two Types of Titration in ParallelBy adding a titration station and stirrer, two types of titration can be carried out in parallel. |
 |
Built-in Thermal PrinterEquipped with a built-in thermal printer with a paper roll 58-mm wide, which can be set up simply by inserting the paper roll and closing the cover. |
 |
USB/LAN PortApproximately 9,900 results can be stored on a USB memory stick. With optional software, the user can view the data on a PC or use a recalculation function. With a LAN connection, the user can also view the data on a Web browser. |
 |
User Authentication SettingsUser restrictions enable the security improvement as well as the prevention of inadvertent changes to, for example, measurement conditions. |
 |
Status Indicator with 3 LED ColorsColored lights allow the user to confirm the status of operation from a distance. The user will also be alerted to unexpected problems right away. |
 |
Easy Replacement of Buret HeadSimply sliding toward the user, Buret Head can be removed together with the reagent bottow just with one hand. With multiple buret heads, the user can quickly manage different titrants simply by switching them. |
 |
Economical Purge FunctionDischarging/charging at the top end of the syringe is repeated. 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 SetRotation can be adjusted manually in fine increments shown by LED bars—it is easy to see and understand. (Four increments per each bar) |
