MEASUREMENT PROCEDURE

• Select the

Cyanuric Acid method using the procedure

described in the

Method Selection section (see page 12).

• Fill the cuvette with 10 mL of unreacted sample (up to the

mark) and replace the cap.

• Place the cuvette into the holder and close the lid.

• Press the

Zero key. The meter will show “-0.0-” when the

meter is zeroed and ready for measurement.

INTERFERENCES

Interference may be caused by large amounts of turbidity that will cause high readings.
Oxidizing (such as chlorine) or reducing agents (such as sulfide or sulfur dioxide) are known to interfere with
the measurement. Distillation will remove these.
Samples with high pH values should be adjusted to approximately pH 7 before testing.

CAUTION: cyanides, their solutions, and hydrogen cyanide liberated by acids, are very poisonous.

• Press ▲ or ▼ to access the second level functions.
• Press the

Chem Frm key to convert the result in mg/L of Potassium Cyanide (KCN).

• Press ▲ or ▼ to return to the measurement screen.
Note: for most accurate results perform the test at 20-25 °C.
