Double High Impedance Online PH Sensor Immersion Mounting
KPH310 Online PH Sensor Signal Output: RS-485 Double High Impedance Differential Amplifier Ip68
For environmental water quality monitoring, acid/alkali/salt solution, chemical reaction process, industrial production process, can meet the majority of industrial applications online pH measurement requirements.
- Signal Output: RS-485(Modbus/RTU protocol).
- Convenient to connect to PLC, DCS, Industrial Control Computer, General Controller, paperless recording instrument or touch screen, and other third-party equipment.
- Double high impedance Differential amplifier, strong anti-interference, fast response.
- The patented pH probe, with an internal reference fluid at a pressure of at least 100 kpa (1 bar), oozes extremely slowly from the microporous salt bridge, with a forward exudation lasting more than 20 months. Such a reference system is very stable, electrode life than ordinary industrial electrode times longer.
- Easy to install: submerged installation.
- Ip68, protection level.

Tips: Q&A
1.What is the difference between ORP and pH?
ORP is like pH in that pH indicates how acidic or basic a solution is based on the hydrogen ion activity within the solution and ORP indicates the reduction- oxidation status of a solution based on the collective electron activity within the solution.
2.What is a good ORP level?
Normal tap water, bottled water, rain water, and so forth, have a positive ORP generally between 200-400 mV,8 and even as high as 500-600 mV depending on location.
3.Is negative ORP good?
The more positive ORP, the more oxidize the solution is, that means the solution has a higher ability to destroy harmful contaminants. ... The more negative ORP reading, more anti-oxidizing the solution is, that means the solution contains less dissolved oxygen as the organics are consuming the oxygen.
