Double High Impedance Online PH Sensor with RS-485 Output for Immersion Mounting Water Quality Monitoring

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 ORP in pH meter? What is an ORP Measurement?

ORP is short for oxidation-reduction potential, also known as REDOX, which means the degree a substance is capable of oxidizing or reducing another substance. This is measured by millivolts (mV) on an ORP meter, or a REDOX sensor.

2.What does an ORP meter measure?

Oxidation-reduction potential, or ORP, is a measure of a substance's ability to either oxidize or reduce another substance. It is measured by the electrodes of an ORP meter.

3.Does ORP affect pH?

ORP decreased with increasing pH, regardless of the oxidant type or concentration.
