pH-value 6.5 - 8.4
Perform zero calibration (see "Operation").
Add a PHENOLRED/PHOTOMETER tablet to the 10 ml water
sample straight from the foil and mix to dissolve using a clean
stirring rod. Screw the cap on and replace the vial in the sample
chamber making sure that the ∇ and ∆ marks are aligned.
Press the ZERO/TEST key.
The method symbol flashes for approx. 3 seconds.
The pH value is shown in the display.
Tolerance: bis 0.3 pH-Einheiten
up to 0.3 pH units (see Notes on chemical methods).
Cyanuric acid 1 - 80 mg/l
Perform zero calibration (see "Operation").
Add a CYANURIC ACID tablet to the 10 ml water sample straight
from the foil and mix well to dissolve the tablet using a clean stirring
rod. The presence of cyanuric acid will cause the solution to take
on a milky appearance.
Screw the cap on and shake the vial for 1 minute. Replace the
vial in the sample chamber making sure the ∇ and ∆ marks are
aligned.
Press the ZERO/TEST key.
The method symbol flashes for approx. 3 seconds.
The result is shown in the display in mg/l cyanuric acid.
Tolerance: ± 5.0 mg/l
