YANTAI STARK INSTRUMENT CO., LTD.

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

compatibility.

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