OliSens activity

We want to deliver to people in charge of water quality mangement, some devices that deliver robust measured values, on site, in real time, to give them capacity to make the right decision, on time.

Having the result of measurements in 4 minutes instead of 3 to 10 days!

That will help industry to reduce the impact of its activity (water footprint, carbon footprint, biodiversity) on environment!

With OliSens technologies and devices, you will know in real time what are the concentration of various pollutants in your water. Thus, you will be able :

  • to optimise your process by delivering the right quantity of traitement at the right moment, on various chemical process such as :
  • – Drinkable water production
  • – Chemical production process
  • – Industrial Waste Water Treatment
  • to manage crisis with relevant and affordable data that permit to- to characterise the nature and the intensity of some pollutions
  • – to decide rapidly about turning off pipes or launching specific treatment
  • – to inform authorities and users in real time


OliSens developed two technologies. IonSens and MetalSens. Both have the following characteristics in common:

  • Accurate and robust
  • – Limit of quantification of 1 mg/L for IonSens
  • – Limit of quantification of 1 µg/L for MetalSens
  • – With résistance to mater matrix changes

  • Usable on site
  • – on portable device
  • – on online device

  • In real time
  • – Measurement time from 2 to 6 minutes
  • – Measurement cycle (including measurement time from 8 to 13 minutes
  • User-friendly
  • – No specific skills are required
  • – Tutorial on touch screen

  • Low impact
  • – No CMR product are used
  • – Waste in the sink

  • Taylor made on request
  • – Measurement protocole could be adapted
  • – Device could be adapted

Targetted pollutants and limit of quantification are the following:


OliSens can implement IonSens and MetalSens on portable device (more suitable for rapid diagnostic on site) and online device (more suitable for treatment process management).
