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.
