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 microcomputer |
| processing technologies and can be used for the measurement of the PH values and temperature, automatic |
| temperature compensation and self-checking. |
| Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjusting |
| knob or potentiometer arranged on this instrument. |
| 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. |
| Solution grounding: This can eliminate all the disturbance of the ground circuit. |
| Isolated current output: Optoelectronic isolating technology is adopted. This meter has strong interference |
| immunity 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 is |
| within 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 easily |
| operated 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 status |
| can be displayed on the screen at the same time. |
