HI721 Iron Checker - Hanna Instruments

Description

The Hanna Iron Checker bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Iron Checker uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
The HI721 Checker HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure iron. Naturally present in water in low concentrations, iron may affect the taste of water, as well as stain both laundry and household appliances. Also an indicator of corrosion, iron is monitored in industrial plants and water cooling and heating systems.
