SJG-3083 INDUSTRIAL ACID ALKALI CONCENTRATION METER
SJG-3083 is our company’s latest micro-computer based high-end instrument. All the information in the instrument is displayed in English. It is characterized by complete English display, English menu operation, intelligence, multiple functions, high measuring performance, and strong environment adaptability. It can be widely used in thermal power plants, chemical industry and other industries. It can be used to test the concentration of the regenerated liquid in high-purity water preparation process by means of ion exchange. It can also be used for continuously monitoring the concentration of the Acid and Alkali in the pickling solutions for clean boilers and pipelines.
New Design, Aluminium shell, high level E-time water analyzer.
SJG-3083 English On-line Acid Alkali Concentration Meter adopts high-precision AD conversion and single chip microcomputer processing technologies. It can be used for the measurement of the HCl, NaOH concentration and temperature, automatic temperature compensation, automatic range switching and self-checking.
All the components are arranged on one circuit board. No complicated functional switch, adjusting knob or potentiometer is arranged on this instrument.
Strong interference immunity
Its current output adopts optoelectronic isolating technology. This meter has strong interference immunity and the capacity of long-distance transmission as well as excellent electromagnetic compatibility.
Waterproof and dust-proof design
Its protection grade is IP54. It is applicable for outdoor use.
Automatic range switching
The measuring ranges can automatically switch within the measuring range of the electrode.
RS485, It can be easily connected to a computer to perform monitoring and electrode.
Phase sensitive detection
Eliminating the influence of conductors on the measurement of hydrochloric acid alkali concentration.
Automatic measuring frequency switching
This can help prevent electrodes from polarization, so as to enhance their accuracy.
