OPTISENS ODO 2000 – Inline version for insertion

OPTISENS ODO 2000 optical oxygen sensor for water and wastewater applications

The OPTISENS ODO 2000 is a dissolved oxygen sensor with integrated temperature compensation. The optical sensor can be deployed in any size of water treatment plant to monitor and control oxygen concentration. The OPTISENS ODO 2000 operates with the OPTISENS MAC 100 analytical transmitter.

Product highlights

  • Precise dissolved oxygen measurement in the ppm range with a resolution of 0.01 ppm
  • Long-term stability due to reduced clogging by integrated spray cleaning nozzle (immersion version only)
  • No media flow required
  • Fast response times for all applications
  • Long maintenance intervals: Optical membrane life >1 year (not exposed to sunlight)
  • Calibration and configuration with the MAC 100analytical transmitter
  • Easy exchangeable optical disk
  • Mounting option on a flexible telescopic rod (SENSOFIT IMM 2000) or via a flow-through assembly (SENSOFIT FLOW 2000 T or SENSOFIT FLOW 2000 Flow Cell)

Typical applications

Water and wastewater industry
