Hanna (HI721) Iron Checker HC Handheld Colorimeter 0.00 to 5.00 ppm Range
HI721 Iron Checker HC Handheld Colorimeter
Portable photometer for accurate iron level monitoring in water, bridging the gap between test strips and lab equipment
The Hanna HI721 uses silicon photocell detection technology to measure iron concentration with ±0.04 ppm or ±2% accuracy at 25°C. Simple three-step operation: zero with your sample, add reagent, and read results. Powered by a single 1.5V AAA battery with auto-shutoff after three minutes of inactivity.
Professional-Grade Iron Detection
Silicon Photocell Detection
Advanced light detection technology measures the orange tint produced when reagent reacts with iron in water samples
0.00 to 5.00 ppm Range
Ideal measurement range for ground water, industrial runoff, and agricultural water quality monitoring applications
Fast Results
Get accurate iron concentration readings within seconds of adding reagent to your water sample
Laboratory Accuracy
±0.04 ppm precision using adaptation of Standard Method 3500-Fe B, far exceeding chemical test kit accuracy
Wide Operating Range
Functions in temperatures from 0 to 50°C (32 to 122°F) with RH max 95% non-condensing conditions
Compact & Portable
Measures just 81.5 x 61 x 37.5 mm (3.2 x 2.4 x 1.5") and weighs only 64 g (2.25 oz) for field testing
Water and Soil Analysis
The Hanna HI721 Iron Checker HC is designed for monitoring iron levels in ground water systems, industrial effluent, agricultural runoff, and mining discharge. Ideal for well water testing, RO system pre-treatment analysis, and environmental monitoring programs. Includes two sample cuvettes with caps, six powder reagents, and 1.5V AAA battery to begin testing immediately.
Hanna Instruments has been manufacturing vertically integrated analytical instrumentation since 1978, maintaining complete quality control without subcontracting.
