CX-IAC-1403 Industrial Alkali Concentration Meter
CX-IAC-1403 Industrial Acid Concentration Meter is our company’s latest micro-computer based high-end instrument. All the information in the instrument is displayed in Chinese. It is characterized by complete Chinese display, Chinese menu operation, 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 NaOH in the pickling solutions for clean boilers and pipelines.
 
Features:  
Intelligent: CX-IAC-1403 Chinese On-line Acid 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, 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 IP65. It is applicable for outdoor use. 
Automatic range switching: The measuring ranges can automatically switch within the measuring range of the 
electrode.
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.
