HI 93741

Total Hardness & Iron LR

The HI 93741 meter measures the Iron (Fe) content and the Magne-

sium (Mg), Calcium (Ca) and Total Hardness in water and wastewater.

SPECIFICATIONS

Range Fe 0 to 400 µg/L

Mg Hardness 0.00 to 2.00 mg/L

Ca Hardness 0.00 to 2.70 mg/L

Total Hardness 0.00 to 4.70 mg/L

Resolution Fe 1 µg/L

Hardness 0.01 mg/L

Accuracy Fe ±10 µg/L ±8% of reading

Hardness ±0.11 mg/L ±5% of reading

Typical EMC Fe ±1 µg/L

Deviation Hardness ±0.02 mg/L

Light Source Light Emitting Diode @ 555 nm

Method For Iron, Adaptation of the TPTZ Method. The

reaction between iron and the reagent causes a

blue tint in the sample.

For Hardness, adaptation of the Standard Meth-

ods for the Examination of Water and

Wastewater, 18

edition, Calmagite/colorimet-

ric method. The reaction between hardness and

reagents causes a maroon tint in the sample.
