Photometer วัดวิเคราะห์เหล็กในน้ำ, HI721 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.
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. Designed
as a more accurate alternative to chemical test kits, the HI721
provides quick, accurate results in four easy steps:
