FDR-2251 Automatic acid and base tester of petroleum products

Scope
Compliance with SH / T 0251 "Determination of base number of petroleum products (perchloric acid potentiometric titration)" and GB / T 7304 "Petroleum products and lubricants and values ​​assay (potentiometric titration)" standard laboratory requirements.
Features
1, the use of liquid crystal display, English operation interface, can display information about the test parameters and measurement results
2, with pre-titration, preset end point 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, complexation 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-corrosion materials, can be a variety titration
