Having a stable, reliable and accurate measurement is of vital importance for pH measurement and control. The SC25V pH sensor has been developed and designed to make sure that this sensor will deliver these results in every application.
The built-in temperature sensor is located close to the pH measuring glass. This will result in an increased accuracy of the temperature compensation and therefore also the pH measurement. The integrated large Titanium liquid earth will improve the stability measurement countering any stray or ground loop currents that can destroy the reference sensor.

On-line measurements often present extra challenges, especially when routine maintenance is required. The PR10 is ideally suitable for applications where the sensors must be removed without interrupting or shutting down the process. Without any special tools the PR10 can be retracted safely from the process at pressures up to 5 bar (72 psi). Using the PR10 allows us to place any dissolved oxygen sensor that has a PG13.5 connenction into a retractable assembly.
Yokogawa has invested considerable design and development time in producing a full range of fittings with particular emphasis on designs that reduce installation and maintenance time and consequently save operation costs.
The immersion fittings are designed for either pH or ORP (Redox) measurements in tanks, open vessels and drains. They have a "hoisting cable" for easy maintenance.
In stable dispersion of fine particles is the pre-requisite for the selective flocculation technique involving separation of ultra-fine valuable particles from the gangue. Among mineral processing techniques selective flocculation technique is known to have outstanding potential of capturing the particles of particular mineral in slurry of mixed mineral system by selective adsorption of water soluble polymers known as flocculants.
In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH)2) slurry, the consumption of the desulfurization agent (Mg(OH)2) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH)2 slurry. To ensure accurate measurement, frequent cleaning of the electrodes with an acid is required, adding to both maintenance workload and cost.
Where and why are the pH Measurements important in a brewery? No one wants a skunky beer. pH measurements in the wort, during mashing/souring the malt, and in the yeast enzymes are critical.
For control of batch neutralization, a pH measurement coupled with a timer-controlled chemical feed scheme provides very satisfactory results.
This system can be adapted for either acid waste or alkaline waste neutralization.

Are Pure water, Ultrapure water, UPW, or Water for Injection (WFI) important in your process? Would a better understanding of current water treatment equipment technology be useful? Would learning to better identify sources for potential process problem be helpful?
Pure water, Ultrapure water, UPW, Water for Injection (WFI), high-purity water and deionized (DI) are all terms describing basically the same property. They refer to water which has been purified to the highest standards by removing all contaminants such as, organic and inorganic compounds; dissolved and particulate matter; volatile and non-volatile, reactive and inert; hydrophilic and hydrophobic; and dissolved gases. Pure water or conditioned water is used in a variety of processes across various industries; Power Generation, Pharma/Biotech, Semiconductor, and Drinking water are just a few examples. Please join us for a free 45 min webinar with 15 min Q&A section. As our presenter David H. Paul, Inc (DHP), gives an overview of high purity water treatment. What you will learn:
- Understanding the purpose for each piece of equipment in a high purity treatment process flow
- Basic overview of Reverse Osmosis Processes
- Better understanding of when to "raise an alarm" when performance issues arise

Proper pretreatment is critical for minimizing problems and reducing the need for chemical cleaning. This webinar will teach you the most common pretreatment technologies and why it is important to monitor and maintain them. Join us to learn:
- Why pretreatment is important
- How pretreatment protects your RO units from scaling, fouling and chemical attacks
- What to monitor and why
Basic pH/ORP Theory and gain an understanding of:
- How pH and ORP measurement works
- The differences in measuring electrodes and reference electrodes
- The difference between ORP and pH compensated ORP
How to choose the right reference and measuring electrode for your application, which includes:
- The differences and benefits between all-in-one vs. individual electrodes
- The benefits of SMART sensors
- The difference between traditional and differential pH maintenance
- Best practices for cleaning and calibrating
- The benefits of sensor diagnostics and how to interpret the information
Each of the previous webinars covered the basics and the monitoring requirements for a high purity water treatment system that included a Reverse Osmosis (RO) treatment step. In this final webinar, we cover the problems that poor RO unit performance can produce in downstream process steps and in the end use water. The webinar series started with topics concerning raw water contaminants and will end with following contaminants through the RO membrane and into downstream treatment steps including Electrodeionization (EDI), mixed-bed ion exchange, 185 nm and 254 nm UV, ozone and more. Join us and learn:
- What and why certain measurement parameters should be monitored
- When to "raise the alarm" when issues arise
A common use for RO is for purifying water, removing salts and other impurities to improve the color, taste and other properties. It is regularly used for commercial and residential water filtration and is also one of the methods used for desalinization of seawater. RO systems are capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents which have a molecular weight of greater than 150-250 Daltons. RO systems are designed for automatic operation and require routine preventative and corrective maintenance. Common problems include membrane fouling and the use of improper flow rates. The result is reduced throughput capacity and shortened runs. What you will learn:
- Overview of Reverse Osmosis Processes
- Understanding of RO technology
- Understanding the importance of RO operation and maintenance
