Analogue Glass pH Electrode with Digital Memosens Technology
This Glass pH Electrode has been designed for the long-term monitoring and limit value monitoring of processes with stable process conditions such as those found in the chemical industry, power plants, incinerator plants, and numerous water and waste water treatment applications. This Glass pH Electrodes come with ATEX, IECEx, FM, CSA, TIIS and NEPSI approval for use in hazardous areas.
The pH value is used as a unit of measurement for the acidity or alkalinity of a liquid medium. The membrane glass of the electrode supplies an electrochemical potential which is dependent upon the pH value of the medium. This potential is generated by the selective penetration of H+ ions through the outer layer of the membrane. An electrochemical boundary layer with an electric potential forms at this point. An integrated Ag/AgCl reference system serves as the required reference electrode. The transmitter converts the measured voltage into a corresponding pH value.
Analogue Glass pH Electrode Specifications
- Low-maintenance and robust thanks to large PTFE ring junction
- Can be used at pressures from 1 to 7 bar (15 to 101 psi)
- pH Glass membrane
- pH 1 to 12, temperature range -15 to 80 °C
- Integrated NTC30K temperature sensor
- Memosens plug-in head pg 13.5
- Maximum process safety, IP68 rated
- Viton O ring with thrust collar, PTFE diaghragm
- Data security thanks to digital data transmission
- Very easy to use as sensor data saved in the sensor
