SJG-3083 industrial acid-base concentration meter is our company’s new generation of Chinese (English) microcomputer type high-end instrument, with Chinese (English) display, Chinese (English) menu operation, full intelligence, multi-function, measurement performance High, environmental adaptability and other characteristics. It can be widely used in thermal power, chemical and other industries. It is suitable for checking the concentration of regeneration liquid in the process of producing high-purity water by ion exchange, or for preparing pickling liquid for boilers and pipelines, and continuously monitoring the concentration of acid, alkali and salt in the solution.
Instrument features : new layout design, cast aluminum shell, metal texture, to create a high-grade E era water meter!
Full Chinese (English) display, friendly interface, multi-parameter simultaneous display: simultaneous display of conductivity, output current, temperature, time and status on one screen. Adopt high-resolution dot matrix liquid crystal display module, all data, status and operation prompts are displayed in Chinese (English), and there is no symbol or code defined by the manufacturer at all.
Fully intelligent: using high-precision AD conversion and single-chip micro-processing technology, it can complete various functions such as HCL;
High reliability: The components are integrated into a circuit board, and there are no complicated function switches, adjustment knobs and potentiometers.
Strong anti-interference ability: The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and realizes remote transmission. Has good electromagnetic compatibility.
Waterproof and dustproof design: The protection grade is IP54, and the cast aluminum shell is suitable for outdoor use.
Automatic range conversion: automatic range conversion is realized within the measurement range covered by the electrode.
RS485 communication interface: It can be easily connected to the computer for monitoring and communication.
Phase-sensitive detection: Eliminate the influence of wires on the measurement of hydrochloric acid concentration.
Automatic conversion of measurement frequency: avoid electrode polarization and improve measurement accuracy.
