Oil in Water Sensor

SMART ABOW is a new generation of immersion sensors for the measurement of oil or hydrocarbons in water based on the UV fluorescence principle. When excited by a light beam at a specific wavelength, some compounds re-emit light at a longer wavelength. Since there is a very limited number of chemicals such as PAH that have fluorescence signatures, this method gives a highly selective measurement with much higher sensitivity than the conventionally used infrared-based technology. This makes it possible to determine even the slightest traces of PAH’s.
