SJG-2083C High range HCL/H2SO4 / HNO3 Acid concentration analyzer controller 

SJG-2083C Industrial online Acid Concentration Meter is our company’s latest micro-computer based high-end instrument. All the information in the instrument is displayed in English. It is characterized by complete English display, English menu operation, intelligence, multiple functions, high measuring performance, and strong environment adaptability. It can be widely used in thermal power plants, chemical industry and other industries. It can be used to test the concentration of the regenerated liquid in high-purity water preparation process by means of ion exchange. It can also be used for continuously monitoring the concentration of the hydrochloric acid in the pickling solutions for clean boilers and pipelines. 

Features

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.
