Principle of Operation

The TU5 Series turbidimeters utilize a 360° x 90° optical design to measure turbidity. A laser is directed into the sample, causing suspended particles to scatter light. The light scattered at a 90° angle is collected by a detector after being reflected by a conical mirror. The amount of scattered light is proportional to the sample's turbidity. This design is optimized for high accuracy at low turbidity ranges and does not include ratio technology, which is typically used for high turbidity applications with color and large particle interference.

Accessories and Calibration

• Calibration: Stablcal calibration sets (with and without RFID), glass rod secondary turbidity standard.
• Vials: Replacement vials for TU5300sc/TU5400sc, sample vials for TU5200.
• Accessories: Automatic cleaning module, flow sensor, desiccant cartridge, maintenance kit, SIP10 sipper unit, manual vial wiper.
• Note: An SC controller is required for operation of the TU5300sc or TU5400sc.
