Parameter
Turbidity Meters & Online Turbidity Analysers
Turbidity is the key indicator of filtration performance and a pre-condition for effective disinfection. Low-range accuracy matters most on filtered and final water.
LimitSANS 241: ≤ 1 NTU (operational), ≤ 5 NTU (aesthetic).
Measurement options
Laboratory, portable and online Turbidity measurement
Laboratory
Ratio turbidimeters compliant with EPA 180.1 or ISO 7027, with primary formazin or StablCal standards.

Common questions
EPA 180.1 or ISO 7027: which do I need?
EPA 180.1 uses a tungsten lamp and ISO 7027 uses an infrared LED, which reduces colour interference. Match the method to your permit or reporting requirement.
Why do my lab and online turbidity readings differ?
Air bubbles, sample-line fouling, different optical designs and calibration standards all cause differences. Verify both instruments against the same standard and keep sample lines short and clean.
