Description

SE707 Oxygen Sensor | Memosens | 220 mm | Ex | Measuring range (resolution) 0 ... 50 mg/l (1 μg/l)

Reliable measurement of oxygen traces, also under sterile and hygienic conditions; signal-stable and robust, digital, with Memosens technology.

  • perfect galvanic isolation thanks to Memosens technology
  • precalibration in the lab
  • no influence of humidity in the connector
  • digital data transfer
  • integrated sensor diagnostics
  • high level of process safety
  • durable materials
  • robust design
  • easy to clean thanks to extremely smooth surface
  • very simple calibration in air without calibration gases
  • very high resolution of 1 ppb in the trace range
  • cost-efficient service due to easy-to-replace membrane module and interior body
  • hygienic design
  • low cross-sensitivity to CO2
  • operation also in hazardous locations

High resolution of low oxygen concentrations, simple and cost-efficient sensor calibration in ambient air. No calibration gases. High signal stability, also in the presence of high CO2 partial pressures.

FDA-conforming material with extremely smooth polished surface. Simple maintenance due to modular design. Sterilizable, autoclavable, and CIP capable. Also suitable for hazardous locations.

Applications
Beverage filling (e.g. milk, beer), measurement in boiler feed water (detection limit 1 ppb)
