iSOLV ATS500 sensors based on nephelometry measure turbidity according to ISO 7027 / EN 27027. They feature an LED lamp and a light detector that is positioned in a 90 degree angle. The lamp emits a beam into the medium, where it generates a scattered light as soon as it hits a particle in a defined area. The detector converts the received light intensity into an electric signal. This signal is then translated into the final turbidity value and can be displayed by the transmitter in the desired unit.

- Our turbidity probes provide you with full flexibility. Mount them directly in the pipe or in a flow assembly for fast inline measurement without product loss or install them with a holder in any open channel, basin or tank.

- Our turbidity transmitters process the measuring signal of each turbidity meter and display it based on your preference: as FNU (Formazin Nephelometric Unit), FTU (Formazin Turbidity Unit), NTU (Nephelometric Turbidty Unit) and many more.
