SJG-2084 industrial alkali concentration meter

●Overview

   SJG-2084 Alkali Concentration Meter is a new generation of all-Chinese high-end meters RAMZY. It has the characteristics of full Chinese display, Chinese menu operation, full intelligence, multi-function, high measurement performance strong environmental adaptability. Widely used in thermal power, chemical industry other industries, 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, continuous monitoring of NaOH concentration in the liquid.

●Features

Full Chinese display, Chinese menu operation, multi-parameter display at the same time: alkali concentration, output current, temperature, time status.

Fully intelligent: SJG-2084 Chinese online alkali concentration meter adopts high-precision AD conversion single-chip micro-processing technology, which can complete various functions such as NaOH concentration temperature measurement, automatic temperature compensation, instrument self-test.

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.
