Description

SE571 pH Sensor | Memosens | 225 mm | Ex | For demanding applications in the chemical industry

Low-maintenance sensor for demanding process applications in the chemical industry, digital, with Memosens technology.

  • 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
  • PTFE ring junction, no blocking

The special design provides high accuracy, stability, speed, and a long life cycle. Through a PTFE ring junction, the reference system is in direct contact with the measured medium.

There is hardly any risk of contamination or blocking of the junction. A salt reservoir protects against leaching. A special cartridge reference element prevents poisoning of the reference system. Resistant to high pressure.

Applications
Measurement in media of extremely high ionic strength, salt brines, strongly oxidizing media, acidic and alkaline media, also with high content of contaminants, paint shops

We look forward to hearing from you!
