Ph Water Tester PH Controller Analyzer
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.
PH Analyzer Features
New design, Aluminium shell, metal texture.
1. Intelligent: This industrial pH meter adopts high-precision AD conversion and single chip microcomputer processing technologies and can be used for the measurement of the pH values and temperature, automatic temperature compensation and self-checking.
2. Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjusting knob or potentiometer arranged on this instrument.
3. Double high impedance input: The latest components are adopted; The impedance of the double high impedance input can reach as high as l012Ω. It has strong interference immunity.
4. Solution grounding: This can eliminate all the disturbance of the ground circuit.
5. Isolated current output: Optoelectronic isolating technology is adopted. This meter has strong interference immunity and the capacity of long-distance transmission.
6. Communication interface: it can be easily connected to a computer to perform monitoring and communication.
7. Automatic temperature compensation: It performs automatic temperature compensation when the temperature is within the range of 0~99.9℃.
8. Water proof and dust-proof design: Its protection grade is IP54. It is applicable for outdoor use.
9. Display, menu and notepad: It adopts menu operation, which is like that in a computer. It can be easily operated only according to the prompts and without guidance of the operation manual.
10. Multi-parameter display: The pH values, input mV values (or output current values), temperature, time and status can be displayed on the screen at the same time.
