2.2.1 Instrument description
The Surface Scatter
®
7 sc (SS7 sc) Turbidimeter is a sensitive,
continuous-monitoring instrument designed for measuring turbidity
in fluids. The instrument design is based on the nephelometric
principle, where light scattered by particles suspended in the fluid is
measured to determine the relative amount of particulate matter in
the fluid. It meets all U.S. Environmental Protection Agency
(USEPA) design criteria, features an automatic-ranging digital
display and is capable of measuring turbidities from 0–9999 NTU.
Calibration is based on formazin, the primary turbidity reference
standard adopted by the APHA Standard Methods for the
Examination of Water and Wastewater and the USEPA. The
instrument consists of a control unit and a sample unit (Figure 3).
DANGER
The SS7 sc and SS7 sc-HST Turbidimeters are not designed
for use with samples that are flammable or explosive in nature.
If any sample solution other than water is used in this product,
test the sample/product compatibility to assure user safety
and proper product performance.
DANGER
The SS7 sc/sc controller platform product configuration is not
intended for installation in hazardous locations. See the
sc controller platform installation control drawing 58600-78 for
approved hazardous location sensors.
