SJG-3083 Industrial Acid alkali Concentration Meter
SJG-3083 Industrial Acid Concentration Meter is our company’s latest micro-computer based high-end instrument.
It is characterized by display, menu operation, complete 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 hydrochloric acid and alkali in the pickling solutions for clean boilers and pipelines.
Features :
Intelligent: SJG-3083 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 etc |
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. Aluminium shell is applicable for outdoor use. |
Automatic range switching: The measuring ranges can automatically switch within the measuring range of the |
electrode. |
RS485 Communication interface: 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 |
concentration. |
Automatic measuring frequency switching: This can help prevent electrodes from polarization, so as to enhance |
their accuracy. |
