Single Parameter Check – Iron
- Handheld Colorimeter
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Industrial ground and treated waters
- Mining leachate monitoring
- Agricultural irrigation water
About 6.3% of the earth’s crust is made of iron, of which 43% is in soils. The analysis of iron is often performed to monitor ground water and irrigation waters as a gauge of corrosion from industrial settling, and as an indication of the effectiveness of treatment from mining leachate.
The Hanna HI721 Checker®HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution, while professional instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. The HI721 Checker®HC is accurate, affordable and produces immediate results.
The new HI721 Checker®HC portable handheld colorimeter features a resolution of 0.01 ppm and ±0.04 ppm ±2% of reading accuracy. The HI721 Checker®HC uses an adaptation of EPA phenanthroline Method 315B.
The contoured style of this Checker®HC fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.
