HI-721 High Range Iron Handheld Colorimeter - Checker®HC information

Hanna's extended description

HI-721 High Range Iron Handheld Colorimeter - Checker®HC

About 6.3% of the earth crust is made of iron with 43% of this amount held in the soil. As a result, iron is naturally present in most water supplies.

Left in the water, iron will not only stain pipework and swimming pool surfaces, or poison aquatic life, it will also affect the water taste and cause problems with animal feed lines.

Testing should therefore form an important part of any water monitoring process - particularly if you are checking your pool, watching the quality of water in your fish tank or needing to monitor water run-off.
