Details
The Hanna Ammonia High-Range (0 to 99.9 ppm) 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 Ammonia High 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.

More Information
The HI733 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure ammonia. Present in water as a component of the nitrogen cycle, ammonia is excreted from animals and other organisms such as heterotrophic bacteria, actinomycetes, and fungi during the metabolism of proteins and amino acids. Generally present in small quantities in unpolluted waters, higher levels indicate organic pollution and is toxic to aquatic life. Designed as a more accurate alternative to chemical test kits, the HI733 provides quick, accurate results in four easy steps.
Ammonia High-Range Checker - HI733
Ammonia Range 0.0 to 99.9 ppm as NH₄⁺ Ammonia Resolution 0.1 ppm Ammonia Accuracy ±1.0 ppm ±5% of reading Ammonia Method adaptation of the ASTM Manual of Water and Environmental Technology D1426-92, Nessler Method.
