Product description
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. |
