• Add the content of one packet of

HI 93722-0 reagent. Replace the cap and
shake gently for about 10 seconds
(dissolution is not complete). A milky
turbidity will form if cyanuric acid is present.
Note: accuracy is not affected by
undissolved reagent powder.

• Reinsert the cuvet into the holder and

ensure that the notch on the cap is
positioned securely into the groove.

• Wait for 45’, then press READ and “SIP”

will blink during measurement.

• Remove the cuvet.

• The instrument directly displays

concentration in ppm (mg/L) of cyanuric
acid on the Liquid Crystal Display.

Note: discard reacted sample immediately
after measurement, or a white rilm may
stain the glass cuvet.
