Fully intelligent: SJG-2083 uses high-precision AD conversion and single-chip micro-processing technology, which can complete HCL (or sulfuric acid, nitric acid) concentration and temperature measurement, temperature automatic compensation, meter self-check and other functions.

High reliability: The components are integrated on a circuit board without complicated function switches, adjusting knobs and potentiometers.

Strong anti-interference ability: The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and realizes long-distance transmission. Has good electromagnetic compatibility.

Waterproof and dustproof design: Protection grade IP65, suitable for outdoor use.

Phase sensitive detection: Eliminate the influence of wires on the measurement of hydrochloric acid concentration.
