Multi-Channel Acid/Alkali Concentration Meter (SJG-2083D)

SJG-2083D has a large LCD display screen, includes two channel and 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.Features
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 SMTtechnology to complete the multi-parameter measurement, temperature compensation
and instrumentself-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 useTechnical Indexes
