ORAKEL pH sensors measure the online pH of any aqueous solution
- Up to 5 years continuous operation
- Stable and reliable
- Suitable for all potable and process waters
- Suitable for very low conductivity waters
- Integral temperature compensation
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.
pH1-3 are less expensive, more traditional combination electrodes.
Anywhere you have a requirement to measure pH is a suitable application for our pH sensors. 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:
- Remote Sites
- Food Preparation
- Potable Water
- Cooling Towers
- Paper Mills
- Chemically Challenging Applications
The ORAKEL PH sensors can be installed in a variety of auxiliary flow cells and self-cleaning devices.
