CYANURIC ACID MEASUREMENT

• Fill the cuvette with 10 mL of unreacted

sample, up to the mark, and replace the

cap.

• Place the cuvette into the cuvette holder

and ensure that the notch on the cap is

positioned securely into the groove.

• Press ZERO/CFM and the lamp, cuvette

and detector icons will appear on the

display, depending on the measurement

phase.

• After a few seconds, the display will

show “-0.0-”. The meter is now zeroed

and ready for measurement.

• Fill a beaker up to the 25 mL mark with

the sample, add the content of one packet

of HI 93722-0 reagent and swirl gently

to mix. This is the reacted sample.

• Fill a second cuvette with 10 mL of the

reacted sample, up to the mark, and

replace the cap.

• Place the second cuvette into the cuvette

holder and ensure that the notch on the

cap is positioned securely into the groove.

• Press and hold READ/ /TIMER for three

seconds. The display will show the

countdown prior to measurement. An

audible “beep” indicates the end of the

countdown period.
