SJG-2084 Industrial online alkali concentration meter is the new generation full English high-end instrument in our company .It is characterized by complete English show, English menu operation, intelligence, multi-function, high measuring performance, strong environmental suitability etc. It can be widely used for fire power, food chemical etc industry. It is suitable for inspection of ion exchange method for the reclaimed liquid concentration high pure water process, or for the preparation of boiler, pickle of pipe, the concentration of NaOH continuous monitoring.


Complete English display, English menu operation, multi-parameter simultaneously display: Alkali concentration

output current ,temperature, time and status.

Intelligent: SJG-2084 English On-line Alkali Concentration Meter adopts high-precision AD conversion and

single chip microcomputer processing technologies. It can be used for the measurement of the NaOH

concentration and temperature, automatic temperature compensation, self-checking etc multiple functions.

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


Waterproof and dust-proof design: Its protection grade is IP65. It is applicable for outdoor use.
