Industrial PH Meter PHG-3081

PHG-3081 industrial pH 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, high measurement performance, Environmental adaptability and other characteristics. This watch is a highly intelligent online continuous monitoring instrument, which consists of two parts: sensor and secondary watch. It can be equipped with three composite electrodes or two composite electrodes to meet various applications. Can be widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water and other solutions in the continuous monitoring of pH value.
Instrument features: new layout design, cast aluminum shell, metal texture, to create a high-grade E era water meter!
Simple menu structure, text-based man-table dialogue: Compared with traditional instruments, DOG-2082 has a lot more functions, but due to the use of a classified menu structure, similar to the operation method of a computer, it is clearer and more convenient to use. There is no need to memorize the operation steps and sequence of operations; you can operate it without the manual and just follow the prompts on the screen.
Intelligent: Using high-precision AD conversion and single-chip micro-processing technology, it can complete various functions such as pH value and temperature measurement, automatic temperature compensation, and instrument self-checking.
Reliability: The components are integrated into a circuit board, and there are no complicated function switches, adjustment knobs and potentiometers.
Dual high-impedance input: Using new devices, the dual high-impedance input impedance is as high as 1012Ω, and the anti-interference ability is strong;
Solution grounding: Eliminate ground loop interference.
Galvanic isolation output: using photoelectric coupling isolation technology, strong anti-interference ability, can be transmitted remotely;
Communication interface: It can be easily connected to a computer for monitoring and communication.
Automatic temperature compensation: automatic temperature compensation at 0 ~ 99.9 ℃.
Waterproof and dustproof design: IP54 protection grade, suitable for outdoor use. It adopts menu structure, similar to microcomputer operation, easy to operate, and the operation steps are prompted in Chinese throughout the process, which can be easily completed without the need for manuals.
Multi-parameter display on the same screen: display pH value, input mV number (or output current), temperature, time and status on the same screen.
