Description
The Hiranuma automatic titrator COM-A19 Series provides you with the flexibility for your titration needs. Japans leading manufacturer Hiranuma with over half a century of experience in the manufacturing of automatic titration instruments with its latest COM-A19 series presents the most flexible and easy to use potentiometric titrator for a wide variety of applications.
Two Types of Titration in Parallel
Two types of titration can be carried out simultaneously by adding a titration station and a stirrer.
Easy Burette Head Replacement
Burette head can easily be removed just with one hand together with a reagent bottle by simply sliding it towards the user.
This is particularly useful if using multiple burette heads. User can easily manage different titrant by simply switching them.
Economical Purge Function
- Reagents can be automatically replaced, which greatly reduces fluid wastage.
- Discharging / charging at the top end of the syringe is repeated.
- The number of economical purge cycles can be set from 1 to 99.
Multiple layer user settings
Different user levels can be set to improve security by restricting inadvertent usage.
Large Color LCD Touch Panel
A large 8.4″ touch panel screen ensures an easy user interface like entering parameters for tests and selecting menu options. Provided with a replaceable protective film to protect the screen from scratches and wear over the long term.
LCD Display Adjustable in 16 Positions
Each user can adjust the angle of viewing for their convenience. The position can be locked so that it will not move when the screen is pressed.
Status Indicator with 3 LED Colors
Colored lights allow the user to confirm the status of the operation from a distance. The user will also be alerted to unexpected problems right away.
40 stirrer 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)
USB/LAN Port
Approximately 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.
Built-in Thermal Printer
Equipped 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.
