ORAKEL pH sensors measure the online pH of any aqueous solution
Our range of ORAKEL pH Sensors can measure the online pH of any aqueous solution. They are combination glass electrodes with integral reference and automatic temperature compensation which use no reagents, are extremely stable and have reduced maintenance and lower whole-life costs.
The pH5 electrode has a double-junction reference to prevent contamination of the reference from sample components. This design gives the electrode a longer life compared to ordinary electrodes (up to 3 yrs). The electrode also has a hemi-shaped glass measuring surface which is more durable than the traditional bulb-shaped glass. Although they command a higher price in the market place, these sensors are more cost effective with their longer life and lower maintenance requirements, typically only needing calibration once per two or three months.
pH5 and pH6 are particularly sensitive to difficult applications such as very low ionic strength waters or high temperature applications, whereas pH1-3 are less expensive, more traditional combination electrodes.
Anywhere you have a requirement to measure pH is a suitable application for the ORAKEL pH monitor. One area the sensors excel is in the measurement of pH in very low conductivity or ultra clean water. They are also particularly suited to working in sites where reliability and ease of use are most important.
Typical applications include:
The ORAKEL PH sensors can be installed in a variety of auxiliary flow cells and self-cleaning devices.
The ORAKEL can come equipped to automatically clean itself at user defined intervals with all the benefits of no operator intervention for 6 months. The Autoflush is particularly useful in food preparation, pulp and paper, and many applications where there is likely to be a build up of solids in the sample. Autoflush is available for at line, and in line versions including dip and screw in autoclean pipe version.
