- Industrial wastewater treatment
- Non-mechanical ultrasound cleaning
- Guaranteed low Maintenance
- Long-term sensor reliability
- Factory Calibrated
- Long-term stability (SensorCheck function)
- Compliance with EN ISO 7027
Turbidity Measurement according to the Nephelometric Principle:
Using this principle, scattered light is measured at an angle of 90 degree. This method is ideal for low and medium range turbidity up to 4000 FNU. In compliance with EN 27027 and ISO 7027, infra red light with a wavelength of 860 nm is used. This wavelength is outside of the visible range – thus potential coloration of the sample does not effect the measurements.
|FNU; NTU; TEF||0.05 ... 4000 FNU|
|mg/l SiO2; ppm SiO2||0.1 ... 4000 mg/l SiO2|
|g/l TSS||0.0001 ... 400 g/l TSS|
Turbidity measurements in aqueous media with VisoTurb® 700 IQ sensors are carried out nephelometrically in compliance with EN ISO 7027.
