SE554 pH/ORP Sensor | Memosens | 120 mm | Ex | For very high ionic strength media
Description
Low-maintenance sensor for demanding process applications in the chemical industry, digital, with Memosens technology
- Simultaneous measurement of pH and ORP
- Perfect galvanic isolation thanks to Memosens technology
- No influence of humidity in the connector
- Precalibration in the lab
- Digital data transfer
- Integrated sensor diagnostics
- Low maintenance, no refilling of electrolyte
- Integrated temperature detector
- Open junctions, no blocking
The special design provides high accuracy, stability, speed, and a long life cycle. Through 2 open junctions, the reference system is in direct contact with the measured medium. There is hardly any risk of contamination or blocking of the junction. The high content and special distribution of potassium chloride in the polymer reduces measurement disturbances which could be caused by liquid junction potentials.
Applications
Measurement in media of extremely high ionic strength, salt brines, strongly oxidizing media, acidic and alkaline media
We look forward to hearing from you!
