Product Description PHG-3081 Industrial PH Meter PHG-3081 industrial pH meter is our latest generation of microprocessor-based instrument, with English display, menu operation, a high intelligent, multi-function, high measurement performance, environmental adaptability and other characteristics. It is a highly intelligent online continuous monitoring instrument, integrate with the sensor and the second meter. Can be equipped with three composite or two composite electrodes to meet a variety of sites. Can be widely used for continuous monitoring of PH value for thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and water and other solution.Features:Intelligent: This industrial PH meter adopts high-precision AD conversion and single chip microcomputerprocessing technologies and can be used for the measurement of the PH values and temperature, automatictemperature compensation and self-checking.Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjustingknob or potentiometer arranged on this instrument.Double high impedance input: The latest components are adopted; The impedance of the double high impedanceinput can reach as high as l012Ω. It has strong interference immunity.Solution grounding: This can eliminate all the disturbance of the ground circuit. Isolated current output: Optoelectronic isolating technology is adopted. This meter has strong interferenceimmunity and the capacity of long-distance transmission. Communication interface: it can be easily connected to a computer to perform monitoring and communication. Automatic temperature compensation: It performs automatic temperature compensation when the temperature iswithin the range of 0~99.9oC.Water proof and dust-proof design: Its protection grade is IP54. It is applicable for outdoor use. Display, menu and notepad: It adopts menu operation, which is like that in a computer. It can be easilyoperated only according to the prompts and without guidance of the operation manual. Multi-parameter display: The PH values, input mV values (or output current values), temperature, time and statuscan be displayed on the screen at the same time. Technical Indexes1.
