| 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. |
