Scope
According to the people's republic of china national standard gb / t 1792 requirements "mercaptan sulfur distillate fuels assay (potentiometric titration)" under the design and manufacture suitable for measuring the content is within 0.0003 ~ 0.01% (m / m) range, no hydrogen sulfide jet fuel, gasoline, kerosene and light diesel mercaptan sulfur.

Features
1, the liquid crystal display, english operation interface, can display information about the test parameters and measurement results
2, with pre-titration, preset endpoint titration, blank titration or manual titration functions, and can generate special titration mode according to user habits
3, the choice of different electrodes can be: acid-base titration, redox titration, precipitation titration, complexometric titration, and other non-aqueous titration and ph measurement
4, stirring system uses pwm modulation technology, software speed, low noise
5, perchloric acid titration system using anti-corrosive materials, can be a variety titration
