Virtually maintenance-free, optics never touch the sample

The Hach Surface Scatter 7 sc Turbidimeter (SS7) is uniquely designed so that the light source and photocell never come in contact with the sample. In fluids with high loads of suspended solids this makes sample cell cleaning and replacement unnecessary.

Durable-manufactured with corrosion/heat-resistant materials for extended life

All wetted parts of the Hach Surface Scatter 7 sc turbidimeter are made with corrosion-resistant materials for extended life. The photo-detector and light source assemblies are protected from the effects of corrosive vapors and heated samples.

Wide turbidity measurement range

Use the Surface Scatter 7 sc to establish and maintain optimum process control for reliable monitoring. Applications for this version include drinking water effluent, wastewater effluent, flocculation and sedimentation, industrial process water, and food processing waste containing fat, starch, or oil.

The Surface Scatter 7sc turbidimeter can reliably measure turbidity from 0 to 9999 NTU in samples that vary from clear water to corrosive and high temperature paper mill and oil field samples.

Backed by a 2-year Warranty

Consistent with its long-standing reputation for quality and customer service, Hach Company warrants all Surface Scatter 7sc turbidimeters against defects in materials or workmanship for two years from the date of shipment.
