Monitoring your needs
Total Suspended Solids – The relationship between turbidity and suspended solids
can be approximated with correlated data. The QuadoptiX™ bench provides the
performance required to produce reliable data for suspended solids, based on
calculated factors (slope and offset) for turbidity versus suspended solids. Default
factors are not possible due to the unique variety of size, shape and reflectivity of
individual sample matrices.
Calculated factors will provide a rapid qualitative value for Total Suspended Solids
that will be relevant until process conditions change. This reading mode will only
become active upon a site-specific calibration being stored in the Compact
Turbimeter.
Taking Readings
Normal Mode - Choose Reading mode, select Normal and press OK. Insert the
sample with the orientation mark facing forward and press 'Read'. A beep will
sound at the start and end of measurement. Result is displayed in and stored in the
results log with date, time, Operator ID and Sample ID.
(NOTE: See System section for details of the result log).
Average Mode- Choose Reading mode, select Average and press 'OK'. Select the
number of readings required for the averaging function :
Short Average
Medium Average
Long Average
Insert the sample with the orientation mark facing forward and press 'Read'.
The instrument will beep at the start and end of measurement cycle. Result is
displayed on the screen and stored in the log with time, date, Operator ID and
Sample ID.
Continuous-Capture - Choose Reading mode, select 'Continuous- Capture' and
press 'OK'. Insert the sample with the orientation mark facing forward and press
'Read'. A beep will occur at the start and end of each measurement cycle. To store
data in the log, press 'Capture' (repeat as required). To cease measurement, press
'Back' at any time.
