Main Feature:
1. The acid value and base value analyzer adopts new microprocessor technology, which can display relevant test methods, titration curves and measurement results in real time.
2.The acid value and base value analyzer has a good operation interface and is easy to use.
3.The acid value and base value analyzer has a variety of titration modes, including pre-titration, preset endpoint titration, blank titration or manual titration.
4.The acid value and base value analyzer uses different electrodes to carry out different titration, including acid-base titration, redox titration, precipitation titration, complexometric titration, non-aqueous titration and other titration and pH measurement.
5.The acid value and base value analyzer adopts the integrated design of valve burette, which is convenient for users to replace, and reduces the mutual interference problem of different solutions with different titration timing.
6.The acid value and base value analyzer has improved the transmission system, greatly reducing the volume of the instrument and effectively reducing the noise of the instrument.
7.The titration system uses materials resistant to perchloric acid corrosion and can be used for non-aqueous titration.
8.The acid value and base value analyzer has a power-off protection function. The internal stored measurement data and set parameters will not be lost after the instrument has been shut down or abnormally powered off.
9.The acid value and base value analyzer can be connected to the PC through the USB interface and controlled by a specially developed matching titration software. The titration curve and its first and second derivatives can be displayed instantly on the computer. Convenient for editing and modification of titration mode, and statistics of results. The instrument supports the GLP specification and can store up to 200 sets of titration results.
10. The acid value and base value analyzer supports the storage of a set of titration curves.
The instrument supports firmware upgrades, allowing for functional expansion and personalization requirements.
