●Overview

   SJG-3083 industrial acid-base concentration meter is the latest generation of Chinese (English) microcomputer high-end instrument of RAMZY company. It has Chinese (English) display, Chinese (English) menu operation, full intelligence, multi-function, measurement performance High, environmental adaptability other characteristics. It can be widely used in thermal power, chemical industry other industries. It is suitable for checking the concentration of regenerated liquid in the process of preparing high-purity water by ion exchange method, used to prepare boiler pipeline pickling liquid to continuously monitor the concentration of acid alkali salts in the solution.

●Features

The new layout design, cast aluminum shell, metal texture, to create a high-grade E era water meter!

Full Chinese (English) display, friendly interface, simultaneous display of multiple parameters: simultaneous display of conductivity, output current, temperature, time status on one screen. Using high-resolution dot-matrix LCD display module, all data, status operation tips are displayed in Chinese (English), without any symbols codes defined by the manufacturer.

Fully intelligent: Adopt high-precision AD conversion single-chip micro-processing technology, can complete HCL; NAOH other multiple concentration measurement, temperature measurement, automatic temperature compensation, automatic range conversion, instrument self-test other functions.

High reliability: The components are integrated on a circuit board without complex 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 IP54, cast aluminum shell suitable for outdoor use.

Automatic range conversion: automatic range conversion within the measurement range covered by the electrode.

RS485 communication interface: can be easily connected to a computer for monitoring communication.

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

Automatic conversion of measurement frequency: avoid electrode polarization improve measurement accuracy.
