Turbidity Meter – TurbSense®
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
The online TurbSense® turbidity meter can be calibrated by comparison with another measurement device (for example, a hand held turbidity meter), by placing it in a sample with known turbidity (for example, a Formazin solution or a suspension of latex spheres), or by the use of a solid secondary calibration block (please see Technical Note ‘TurbSense® Secondary Standards’ under downloads).
Calibration of TurbSense® is generally quicker and easier than with other turbidity sensors as there is no need to “zero” the sensor as through a clever use of the laws of physics (patented), there is no need for a zero.
