Audited Supplier PHG-2081 Industrial Online PH Meter
As our company's latest PH analyzer, PHG2081 Industrial online PH Meter is a highly intelligent and English liquid crystal 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 or a 2-in-1 PH electrode in order to adapt various conditions.
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 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 0~99.9ºC. |
|
Water proof and dust-proof design: Its protection grade is IP65. It is applicable for outdoor use. |
|
English LED display, English menu operation: It adopts menu structure, 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. |
