Turbidity Meter, Turbidimeter - TurbSense®
The turbidity meter from Pi is the world’s only probe based turbidity meter with a resolution of 0.001NTU. It achieves this through its patented technology that complies with international standard ISO 7027 at the same time that it sets the standard in stability and low maintenance.
The patent relates to the measurement of the emitted light as well as the received light allowing the TurbSense® turbidimeter to vary the light output. Doing this allows for the mathematical correction for zero, zero drift, aging optics and fouling windows. The TurbSense® self-calibrates every time it takes a reading and therefore it is only necessary to check the calibration every several months.

Yes, 50°C or 120°F. This is because the electronics inside the TurbSense® will start to degrade in temperatures higher than that.
Turbidity in water is a measure of how cloudy the water is, and is used in making clean water for people to drink.
Yes, but there are factors end users should consider because the reliable operation of the sensor depends upon a powerful light source and sensitive optics. Reflections from walls and bends in pipes can cause problems in accuracy, so the turbidity of the process stream, the diameter of the pipe and the material used will need to be taken into account.
Larger diameter pipes and those made of less reflective materials are better; additionally, the higher the turbidity the more likely pipe insertion will be effective. At >200NTU, putting a TurbSense® into a pipe shouldn’t be a problem.
Many users who purchase TurbSense® use our AutoClean option to ensure optimum performance; pressurized water cleans the sensor head on a user designed schedule which greatly reduces maintenance times. Ideally the sensor should not be placed in direct sunlight as this can affect the reliability of the sensor.
The specially designed flow chamber provides the ideal environment for the TurbSense®. It removes entrained bubbles, is sealed against ambient light and its black polypropylene construction eliminates internal reflections. It also allows the sensor to be incorporated into a sample line along with other sensors.
For samples with no nucleating or entrained bubbles and an atmospheric drain.
For samples with entrained air and with an atmospheric drain.
For samples with nucleating bubbles (air coming out of solution) or if no atmospheric pressure drain is available
For direct insertion into a pipe.
For mounting the TurbSense® on the end of a pole and dipping it into a tank or body of water.
For mounting the TurbSense® on the end of a pole and dipping it into a tank or body of water when the turbidity is low and sunlight could affect the readings.
A solid calibration standard to check the TurbSense® readings or to be used as a calibration. Available in 0.9 NTU and 18 NTU.
