Polycyclic Aromatic Hydrocarbons Measurement (PAH)

PAH 5000 Probe for Polycyclic Aromatic Hydrocarbons

Immersion probe IP68 for oil-in-water and PAH.


  • Highly sensitive measuring method
  • Short response time
  • No reagents required
  • Minimal maintenance
  • Compact
  • Robust design
  • Easy to install

PAH 5000 excites polycyclic aromatic hydrocarbons (PAH) and oil in water with UV light. These substances reacts by emitting fluorescence light, which is then detected by the probe. This measurement principle is significantly more sensitive than other common methods such as infrared scattering.

The measuring window carries an anti-fouling coating.

  • Drinking water
  • Cooling water
  • Process water (refineries, desalination plants)
  • Rainwater (airport runoff monitoring)
