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
