COM-28/28S fully automatic potentiometric titrator
COM-28/28S fully automatic potentiometric titrator
Product details
The compact body is equipped with a color touch screen, which is very reasonable and combines multiple functions!The paid upgrade from COM-28 to COM-28S can also meet future needs.
- 43-inch color LCD touch screen
Titration curve display
Economic blowing function
Save space
Save data to USB flash drive
Touch panel
Adopting a 4.3-inch color LCD touch screen.
Although small in size, it is easy to see and includes a stylus, so it can be operated accurately.
Titration curve display
Display titration curve in real Thailand.
This makes it easier to consider appropriate measurement conditions and determine the causes of changes and defects in the measurement results
Syringe
In addition to the standard 20 mL, an additional 50 mL is provided, suitable for single measurements exceeding 20 mL, such as for isocyanate (NCO) analysis.
Equipped with an "economical blowing function", it can automatically perform reagent replacement work and reduce waste liquid. (Limited to 10 mL and 20 mL only)
Save space
Width 255 millimeters, depth 290 millimeters.
The mixer and burette are integrated, occupying small space and easy to move.
data management
In addition to being able to store 50 data on the host, it can also store approximately 9900 data on USB storage. Using optional software, you can view the results on your PC and use the recalq function.
Sequential measurement (COM-28S)
Different components in a gentleman/lady can be measured sequentially.
You don't need to prepare for every Mr./Ms. pull, the result is automatically obtained, so there's no trouble.
Up to 3 items can be measured continuously.
Extended Features (COM-28S)
In addition to the built-in burette, two burettes can also be added.
By specifying the burette number, it is possible to respond to various titrations without changing the titrant each time.
Photometric titration (COM-28S)
By connecting optional photometric titration measurement units, it can be used for photometric titration of metal ions, etc.
Smooth (COM-28S)
During the titration process, it becomes easier to determine the endpoint when the inflection point is unclear.
Automatic sampler (COM-28S)
Can connect to optional automatic cycle C-1712.
Even with an increase in the number of samples, efficiency can still be improved by continuously measuring 12 samples. (A separate installation bracket is required)
