A:Brief description:
DSHD-251 Base Number Tester is designed according theindustrial standard of People's Republic of China SH/T0251-93 Test method for alkali value of petroleum products. It isConsistsofDSHD-2A automatic potentiometric titrator, titrate stand and burette.
Its main function is to determine the alkali component of petroleum products and used petroleum products and additives.
B:Main advantages:
1.This instrument adopts principle of acid-alkali neutralization and method of potentiometric titration for perchloric acid to determine the alkali value of sample by
judging the electric potential change to finishing point.
2.This instrument is equipped with 5 pieces of electrodes and 3 pieces of burettes of different specifications.It can satisfy the determination for alkali component of
petroleum products.
3.The measuring range of the instrument is wide,measuring accuracy is high. Accessories complete and convenient to use.
