PHG-3081 online Industrial bench top ph meter
As our company’s latest PH analyzer, PHG-3081 Industrial PH Meter is a highly intelligent instrument for continuous online monitoring. It is made up of two parts: a sensor and a secondary meter. It can be used with a 3-in-1 electrode or a 2-in-1 electrode in order to adapt various conditions. It is applicable for PH measurement of following industries: electric power, environmental protection, chemical industry, petroleum, metallurgy, running water and foodstuff.
Features
New design, Aluminium shell, metal texture.
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 is 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 0~99.9°C. |
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. |
