Total Suspended Solids – When using the Turbimeter
in Total Suspended Solids Reading mode, a calibration
is required to set the relationship between the measured
turbidity values and the 'true' suspended solids value,
determined by gravimetric methods. This calibration can
either be an assigned series of values from the results
log or a simple algorithm with factors provided by the
user. This relationship is typically a straight line and
hence the factors consist of a slope and intercept.
The Compact Turbimeter has two methods of generating
the data for relating the measurement of turbidity to total
suspended solids (TSS):-
1 Correlation – Using the stored turbidity data from
the instrument log and relating it to manually
entered Total Suspended Solids data derived from
elsewhere. The minimum number of correlation
points required is one as the zero point can be used
as a second point. A maximum number of 50 data
points can be used.
2 Factor – Using data manipulated externally, a slope
and intercept for the straight line relationship can be
entered directly. Slope factors range from 0.1 – 50.0
and intercepts can be set from -50.0 - +50.0
