Wall Mount Fiber Optic Oxygen Meter


The OXY-1 WM is a precise single-channel oxygen meter for wall mounting. It is temperature, salinity and pressure compensated and can be used with sensor spots, flow-through cells and oxygen probes for in-line measurement. OXY-1 WM is compatible with sensors type PSt3 (detection limit 0.03 % oxygen, 15 ppb dissolved oxygen). The housing and all connector ducts are splash-proof (protection class IP64) so the device can be installed even in harsh industrial environments.

  • Maximum measurement range from 0 % to 100 % oxygen (optimal 0 - 50 %)
  • Limit of detection 0.03 % oxygen, 15 ppb dissolved oxygen
  • Wall mount with color LCD display
  • Temperature, salinity & pressure compensation
  • Splash-proof, protection class IP64
  • No electrical interferences, due to optical measurement


Resilient Oxygen Meter for Industrial Environments

The OXY-1 WM (trace) with its splash-proof housing & connector ducts is ideally suited for oxygen measurements in harsh environments. Due to the optical working principle measurements can safely be conducted in a secure environment while the wall mount oxygen meter is installed in a separated area. The display and controls allow operating the device even with heavy gloves on. So if you are searching for a precise oxygen measurements system - that is also extremely robust - for your application, the OXY-1 WM devices are your choice.

O2 Measurement with Convenient Wall Mount Device in Biotech & Pharma

The wall mount device is ideally suited for applications in the Biotech & Pharma industries. The space-saving installation and the display that allows fast checks on oxygen levels are just some of the advantages this robust oxygen meter has to offer. It can be integrated in process units via 4 - 20 mA outputs or digitally via RS485 ModBus RTU. A concentration alarm relay is integrated and can be used as process trigger when reaching high or low concentration levels. OXY-1 WM can be applied with probes or flow-through cells (various fiber lengths available), that allow precise online monitoring in steel fermenters, bioreactors and bypasses.
