SJG-3083 Industrial Acid
Alkali Concentration Meter
SJG-3083 Industrial Acid Alkali Concentration Meter 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.
Features
New
Design, Aluminium shell, high level E-time water analyzer.
User-friendly
English display, multi-parameter displayed simultaneously: concentration value,
output current, temperature, time and status. Using high-resolution dot matrix
graphic LCD modules.
Intelligent: 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.
Reliability: 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.
Communication interface: RS485, It can be easily
connected to a computer to perform monitoring and communication.
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.
