The HI 93742 meter measures the iron and manganese content in

water, wastewater and seawater (iron only) in the following ranges:

Iron 0 to 400 µg/L (ppb)

Manganese 0 to 300 µg/L (ppb).

SPECIFICATIONS

Range Fe 0 to 400 µg/L

Mn 0 to 300 µg/L

Resolution 1 µg/L

Accuracy Fe ±10 µg/L ±8% of reading

Mn ±2 µg/L ±3% of reading

Typical EMC ±1 µg/L

Deviation

Light Source Light Emitting Diode @ 555 nm

Method Adaptation of the TPTZ method for iron and

PAN method for manganese. The reaction be-

tween iron or manganese and the reagents

respectively causes a blue or an orange tint in

the sample.

• Fill the cuvet up to the mark with 10 mL of

sample and replace the cap.

• Place the cuvet into the holder and

ensure that the notch on the cap is

positioned securely into the groove.

• Press ZERO and "SIP" will appear on the display.

• Wait for a few seconds and the display will

show "0". Now the meter is zeroed and ready

for measurement.

• Fill a beaker up to the

25 mL mark with the

sample, add the con-

tent of one packet of

HI 93722 reagent and

stir gently to mix.

• Fill a second cuvet with 10 mL of the reacted

sample up to the mark. Replace the cap.

• Reinsert the cuvet into the instrument.

• Wait for 45 seconds and press READ. "SIP" will appear during

measurement.

• The instrument directly displays concentration in mg/L of cyanuric

acid on the Liquid Crystal Display.
