Sample line considerations
Select a good, representative sampling point for optimum instrument
performance. The sample analyzed must be representative of the
conditon of the entire system.
To minimize erratic readings:
• Draw samples from locations that are sufficiently distant from points of
chemical additions to the process stream
• Make sure samples are sufficiently mixed
• Make sure all chemical reactions are complete
Connect the sample stream
Connect sample inlet and drain lines to the fittings on the body of the
instrument (Figure 1 on page 6). Sample inlet and drain tubing are
supplied by the customer. Refer to Specifications on page 3 for tubing
requirements.
Install the sample line(s) into a larger process pipe to minimize
interference from air bubbles or pipeline bottom sediment. A sample line
going into the center of a process pipe is best.
8
English
Figure 6 shows examples of good and bad methods of installing a
sample line into a process pipe.
Notes:
• Keep the sample inlet and drain tubing as short as possible to
minimize lag time of the sample flow.
• Control the flow rate into the instrument with a flow restriction device
on the sample line. Refer to Specifications on page 3 for flow rate
specifications.
Note: Flow rates greater than 750 mL/minute will cause the instrument to
overflow into the drain, decrease the performance of the bubble trap and cause
incorrect readings.

The data log and the event log can be saved in CSV format. Refer to the
sc controller user manual for instructions.
Calibration
Calibration is done in the body of the instrument or using the optional
calibration kit.
Calibration is done using 1 L of 800 ± 50 mNTU StablCal Stabilized
Formazin Certified Standard. Do not use other types or values of
standards. Do not use user-prepared formazin.
The performance specifications given in this manual are based on and
guaranteed only when calibration is done with StablCal Stabilized
Formazin Certified Standard for this instrument. The manufacturer
cannot guarantee the performance of the instrument if calibrated with copolymer styrenedivinylbenzene beads or other suspensions.
Prepare the StablCal® Standard
• Before opening a StablCal Standard bottle, clean the exterior surface
of the bottle with clean water to remove dust or other debris.
• Gently invert the bottle for 1 minute (about 50 inversions). Do not
shake.
Note: The suspension is stable for 30–60 minutes after mixing.
The StablCal Certified Standard is stabilized formazin with a value that is
identified to within ± 1 mNTU. The value, specific to that particular lot of
product, is printed on the label. Lot-to-lot variation will be ± 50 mNTU
from the standard value, with a standard deviation of less than ± 5%
within a single lot.
