ZDJ-4B Auto Potential Titrator
The automatic potentiometric titrator is a laboratory analytical instrument with very high analytical accuracy. It is mainly used for chemical analysis of various components in various industries such as universities, scientific research institutions, petrochemicals, pharmaceuticals, drug testing, and metallurgy.
Features
Ø Dot matrix liquid crystal display, key operation, computer software control simultaneously or separately.Real-time display of relevant test methods, titration curves, and measurement results.
Ø Integrated design of valve burette, easy to replace,and effectively avoiding the problem of mutual interference when using different solutions at different titrations.
Ø Support multiple titration modes such as pre-titration (dynamic titration), preset endpoint titration, mode titration, blank titration, manual titration, etc., and support the generation of special titration modes.
Ø Support various titration methods including acid-base titration, oxidation-reduction titration, precipitation titration, complexometric titration, non-aqueous titration,etc.
Ø Support the establishment, editing, copying and reviewing of titration methods, and pH measurement function.
Ø Data management function: available to store 200 sets of titration results and 1 set of titration curves. Measurement information is in compliance with GLP specifications, which makes traceability information more complete. Also support data deletion, review, printi or output.
Ø Bilingual operation: both Chinese and English languages available.
Ø Power-off protection function.
Ø USB, RS232 to connect PC, and titration special software is provided randomly.
Ø Firmware upgrade; support to connect autosampler via PC.
