Side-Stream Oil/Particulate in Water Analyser

  • Microscopy
  • Ultrasonics

The EX-400 is a side-stream unit that uses video microscopy to measure concentrations of oil in water, Total Suspended Solids (TSS), oil droplet size and gas bubble size, whilst still taking advantage of patented self cleaning technology to keep fouling from impacting the data gathered.


  • Patented ultrasonic cleaning
  • Video microscopy measurement
  • Periodic homogenisation of sample
  • Sample access point
  • Various microscopy measurement ranges configurable
  • Measurement repeatability ±4% of full scale range
  • Particle and droplet size information e.g. Dv10, Dv50 and Dv90 data
  • Immediate on-screen results
  • Remote management and diagnostics
  • Easy to install (no sample conditioning required)
  • Multiple communications options – 4-20mA, HART, Modbus, Extended Ethernet
  • Data and image storage on analyser for up to 120 days
  • Automatic PDF report generation
  • Turbidity detection enables user to identify process upsets


  • Easy to use
  • Ability to measure and distinguish between oil, solids and gas particles
  • Low Cost Of Ownership (COO) with no routine maintenance
  • No degradation of signal or recalibration required
  • Side stream format offers localized sample control
  • Sample point facilitates laboratory correlation
  • Remote control and monitoring (suitable for un-manned locations and remote process monitoring)
