SJG-2083 industrial acid concentration meter

SJG-2083 industrial acid concentration meter

●Overview

   SJG-2083 Chinese online acid concentration meter is a new generation of all-Chinese high-end instrument of RAMZY company, with Chinese LCD display, Chinese menu operation, full intelligence, multi-function, high measurement performance, strong environmental adaptability other characteristics. It is widely used in thermal power, chemical industry other industries. It is suitable for checking the concentration of regeneration liquid in the process of preparing high-purity water by ion exchange method, for preparing boiler pipeline pickling liquid, continuously monitoring the concentration of hydrochloric acid (sulfuric acid nitric acid) in the liquid.

●Features

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

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

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

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

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