The Hanna Bromine 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 Bromine 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 HI716 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure bromine. Introduced as an alternative to chlorine, the use of bromine as a sanitizer is increasing in use in many countries. Bromine is less volatile and has more effective results above a pH of 7.4, but is an overall slower acting disinfectant. Designed as a more accurate alternative to chemical test kits, the HI716 provides quick, accurate results in four easy steps:
0.0 to 8.0 ppm
±0.1 ppm ±5% of reading
adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, DPD method. The reaction between bromine and the reagent causes a pink tint in the sample.
