SC400 Colorimeter
Copper
Switch the unit on using the ON/OFF key.
The display shows the following:
Attention:
The unit is designed to measure copper either with tablet reagents (Cut)
or with powder packs (CuP).
Please select the required method as described below.
Select the test required using the MODE key:
Cut → CuP → Cut → .......... (Scroll)
The display shows the following:
Fill a clean vial with the water sample up to the 10 ml mark, screw the cap on
and place in the sample chamber with the ∆-mark on the vial aligned with the
∇−mark on the instrument.
Press the ZERO/TEST key.
The method symbol flashes for approx. 8 seconds.
The display shows the following:
After zero calibration is completed, remove the vial from the sample chamber.
Add the appropriate reagent; a color will develop in the sample.
Screw the cap back on and place the vial in the sample chamber with the ∆ and
∇ marks aligned.
Press the ZERO/TEST key.
The method symbol flashes for approx. 3 seconds.
The result appears in the display.
The result is saved automatically.
Repeating the analysis:
Press the ZERO/TEST key again.
New zero calibration:
Press the MODE key until the desired method symbol appears in the display
again.

Technical Data
Method notes
Prior to measurement ensure that the sample is suitable for analysis
(no major interferences) and does not require any preparation i.e. pH
adjustment, filtration etc.
Reagents are designed for use in chemical analysis only and should be
kept well out of the reach of children. Ensure proper disposal of reagent
solutions.
Material Safety Data Sheets: available on request.
Copper 0.05 - 5 mg/L with tablets (Cut)
0.0.0
(a) free copper
Perform zero calibration (see “Operation”).
Add one COPPER No. 1 tablet straight from the foil to the 10 ml water sample,
and crush using a clean stirring rod. Allow to dissolve completely, close the vial,
and position with ∇ and ∆ alignment.
Press the ZERO/TEST key.
The method symbol flashes for approx. 3 seconds.
The result is shown in the display in mg/L free copper.
(b) total copper
Add one COPPER No. 2 direct from the foil to the already colored sample
immediately after measurement, and crush using a clean stirring rod. Allow to
dissolve completely, close the vial, and position with ∇ and ∆ alignment.
Press the ZERO/TEST key.
The method symbol flashes for approx. 3 seconds.
The result is shown in the display in mg/L total copper.
(c) combined copper
combined copper = total copper - free copper
Measuring tolerance:
0.05 - 1.00 mg/L: ± 0.05 mg/L
1.00 - 5.00 mg/L: ± 0.10 mg/L
