HI 93743
Iron LR & pH
The HI 93743 meter measures the pH and the Iron (Fe) content in
water and wastewater.
SPECIFICATIONS
Range Fe 0 to 400 µg/L
pH 5.9 to 8.5
Resolution Fe 1 µg/L
pH 0.1
Accuracy Fe ±10 µg/L ±8% of reading
pH ±0.1
Typical EMC Fe ±1 µg/L
Deviation pH ±0.1
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 pH, Phenol red method. The reaction be-
tween pH and the reagent causes a red tint in
the sample.
