Description
Automatic Titrator with Flexibility For How You Need To Use It. Replaces COM-1700 series.
Large Color LCD Touch Panel
A large 8.4" touch panel screen makes text input easy. Selecting functions from the menu is intuitive. The protective film can be replaced to protect from scratches and wear over the long term.
Autosampler options are picyured. Choose between 12 and 24 position autosamplers.
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.
Built-in Thermal Printer
Has a built-in thermal printer with a paper roll 58-mm wide. Simply insert the roll and close the cover to set it up.
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)
