Online Turbidity Meters from Pi are called TurbSense® and include analysers, controllers and monitors which determine true online turbidity and/or suspended solids in water, using a nephelometric measurement of scattered light in accordance with ISO 7027. The TurbSense® sensor uses LED optical technology to provide an extremely stable, accurate, low maintenance sensor.

The TurbSense® online turbidity meter is a breakthrough in measurement technologies in that it automatically varies the light output so that the turbidity can be measured independently of background light and electronic drift.

Ranging from 0.01 NTU to 1000 NTU with a resolution in the 0-10 NTU range of 0.001, the TurbSense® online turbidity meter provides:

  • Excellent resolution
  • Single point calibration
  • The simplicity of a probe
  • Great value for money
  • Long term reliability
  • Autoclean so very low maintenance
  • AutoClean solid state optical sensor – no moving parts
  • Single point calibration – very easy to use
  • Stable and reliable – excellent process control
  • Suitable for all potable, waste and process waters between 0 NTU and 1000 NTU
  • ‘Maintenance free’ – low cost of ownership
  • No ‘zero’ required – improved accuracy at the low end
  • Up to 1 year between calibration – very little drift
  • Up to 10 bar – for inline operation
  • 0.001 resolution
  • Automatic debubbling and bubble removal solutions – no interference from bubbles


The TurbSense® online turbidity meters are available with different controllers giving you the same great performance with different communication, display, and control options. With the TurbSense® range of online turbidity meters, you get everything that you need – and nothing that you don’t, without sacrificing the quality of the measurement.
