SJG-3083 Dustproof Acid Concentration Meter

SJG-3083 Industrial Acid Concentration Meter is our company’s latest micro-computer based

high-end instrument. It is characterized by display, menu operation, complete 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 and alkali in the pickling solutions for clean boilers and pipelines.

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

adjusting knob or potentiometer is arranged on this instrument.

Strong interference immunity: Its current output adopts optoelectronic isolating technology. This meter

has strong interference immunity and the capacity of long-distance transmission as well as excellent

electromagnetic compatibility.
Waterproof and dust-proof design: Its protection grade is IP54. It is applicable for outdoor use.
Phase sensitive detection: Eliminating the influence of conductors on the measurement of hydrochloric

acid alkali concentration.
Automatic measuring frequency switching: This can help prevent electrodes from polarization, so as

to enhance their accuracy.
