Description

SE571 pH Sensor | Memosens | 120 mm | PWIS-free | Ex | For demanding applications in the chemical industry

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

  • Also available as version with-out paint-wetting impairment substances (PWIS-free)
  • 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.

We look forward to hearing from you!
