YANTAI STARK INSTRUMENT CO., LTD.

Intelligent: SJG-2083 English On-line Acid Concentration Meter adopts high-precision AD conversion and

single chip microcomputer processing technologies. It can be used for the measurement of the HCL

(sulphuric nitric acid) acid concentration and temperature, automatic temperature compensation, automatic range

switching and elf-checking.

Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjusting

knob or potentiometer is arranged on this instrument.

Phase sensitive detection: Eliminating the influence of conductors on the measurement of hydrochloric acid concentration.
