• 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.
• Alternatively, wait for 45 seconds then
just press READ/ /TIMER. In both
cases, the lamp, cuvette and detector
icons will appear on the display,
depending on the measurement phase.
• At the end of measurement, the
instrument directly displays concentration
in mg/L of cyanuric acid on the LCD.
