Side-Stream Oil/Particulate in Water Analyser

  • Fluorescence
  • Microscopy
  • Ultrasonics
  • Spectroscopy

The EX-100M is a side-stream oil / particulate in water analyser that combines video microscopy measurement for particle size analysis with the highly accurate Laser Induced Fluorescence oil content measurement technique. This allows measurement of Total Suspended Solids (TSS), oil droplet size and gas bubble size whilst still accurately measuring concentration of oil in water.

In addition to the EX-100M features, the EX-1000M model offers spectral analysis.


  • Patented ultrasonic cleaning
  • Combination of Laser Induced Fluorescence (LIF) and video microscopy measurement
  • Periodic homogenisation of sample
  • Sample access point
  • Various microscopy measurement ranges configurable
  • Measurement repeatability ±1% of full scale range (fluorescence and microscopy)
  • Particle and droplet size information e.g. Dv10, Dv50 and Dv90 data
  • Immediate on-screen results
  • Remote management and diagnosis
  • Easy to install (no sample conditioning required)
  • Multiple communications options – 4-20mA, HART, Modbus, Extended Ethernet
  • Integrated spectrometer
  • 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
  • Droplet size compensation with homogenized samples
  • Sample point facilitates laboratory correlation
  • Remote control and monitoring (suitable for un-manned locations and remote process monitoring)
