Single Parameter Check – Iron

  • Iron CheckerHandheld Colorimeter
  • Easier to use and more accurate than chemical test kits
  • Dedicated to a single parameter
  • Small size, big convenience

Ideal for:

  • 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.

HI7210.00 to 5.00 ppmHI721 Checker®HC is supplied with sample cuvettes with caps (2), iron HR reagent starter kit (reagents for 6 tests), battery, instructions and quick start guide.£60.00Buy Now
