Outstanding results in high temperatures: Surface Scatter 7 sc
Able to measure very high and low turbidity levels accurately, this turbidimeter is uniquely designed so that the light source and the photocells never come in contact with the sample.
The sample is introduced into the center sample tube of an inclined turbidimeter body at a flow rate of 1 - 2 liters per minute. As the fluid spills over the top of the turbidimeter body, a stable, flat surface of liquid forms and becomes the measuring surface.
The light source emits a high-intensity beam of light, which strikes the surface of the fluid diagonally. The detector registers the light that is scattered at 90° to the incident beam. This scattered light is proportional to the content of suspended particles in the sample.
Benefits
Less fouling for easy maintenance
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.
Built to Last
All wetted parts of the Hach SS7 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. The SS7 turbidimeter is warranted against defects in materials or workmanship for two years from the date of shipment.
Wide Measurement Range
The SS7 turbidimeter can reliably measure turbidity from 0.01 to 9999.9 NTU in samples that vary from clear water to corrosive and high temperature paper mill and oil field samples.
