The Hanna Iron Checker ® (Low Range) 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 absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Iron Low Range 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 HI746 Checker®HC (Handheld Colorimeter) is a simple, accurate and cost-effective way to measure iron in the low range. 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 HI746 provides quick, accurate results in four easy steps:
0 to 999 ppb
±20 ppb ±5% of reading
adaptation of the TPTZ method.
1.5V AAA / 10,000 hours of continuous use
0 to 50°C (32 to 122°F); RH max 95% non-condensing
after ten minutes of non-use
Photometer/Colorimeter Light Source
LED @ 610 nm
Photometer/Colorimeter Light Detector
