KPH310 Online PH Sensor with Double High Impedance IP68 Immersion Mounting and RS-485 Signal Output for 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.

48.What is in the aqueous process that will challenge the pH electrode?

For example:

What is the maximum temperature of the water?

Extremely high temperatures may damage the materials of the pH sensor. the reasonable temperature range is 0℃-65℃

Are you measuring pure water or is there any hydrofluoric acid present within the process?

Standard pH sensors will not perform for the long term in these types of environments and will lead to inaccurate pH measurements. For these process environments, Kacise has specially designed versions of our industrial pH sensors for low conductivity (-LC) or applications where hydrofluoric acid (-HF) is present.

49.Are there any known ground loop issues?

With process pH sensors, a ground loop is an unwanted electrical current path, in the system, where stray signals cause interference in the pH measurement. If this is a recognized issue, you will want to use a pH sensor that has a solution ground electrode to handle this stray voltage in the process system. The Kacise 310 pH sensor has this as a popular measurement option.

50.What is your preferred price point for a process pH sensor?

This is always the golden question, but is also important to consider the value in different styles of pH sensors while making your decision.

To assist with weighing features and value versus price, Kacise has developed a tiered offering based off of application needs that will benefit you while making the best choice when considering industrial process pH sensors.
