Product name : Multi Channel Industrial Acid/Alkali Concentration Meter
Product No. : SJG-2083D
             [Next Product]→

SJG-2083D has a large LCD display screen, includes two channel or four channel. It can be connected with two concentration meter electrode measurements for HCL and NaOH, the first channel is HCL, the second channel is NaOH, simultaneously measurement, display on same screen. It also can simultaneously measure the concentration of other acid/alkali salt, including nitrate, sulfate, sodium chloride.


Between the two channels are independent, without interference. English LCD display, English menu operation.

Microcomputer: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT

technology to complete the multi-parameter measurement, temperature compensation and instrument

self-checking, with high precision and good repeatability.

Phase sensitive detection: Eliminating the influence of wire on the measurement

Waterproof and dust-proof design: Its protection grade is IP65. It is applicable for outdoor use
