Test Kit Bromine( Colour Card)
Bromine test kits with colour cards are diagnostic tools used to measure bromine sanitiser levels in water (pools, spas, hot tubs) to prevent bacteria growth and ensure safety. They typically use a DPD or OTO reagent to turn water yellow or pink, which is then matched against a colour card to read ppm levels.

Key Uses of Bromine Test Kits
Swimming Pool & Spa Maintenance: Regularly monitoring bromine levels (ideal range 3-5 ppm) in hot tubs, spas, and pools to ensure sanitation.
Water Treatment Facilities: Monitoring bromine levels in treated water to comply with health standards and prevent corrosion.
Industrial Cooling Systems: Used as a biocide in cooling towers to prevent microbial growth and system damage.
Chemical Balance Management: Ensuring proper bromine levels without overuse, which can lead to skin irritation or costly waste.

How to Use the Test Kit (Common Methods)
Sample Collection: Fill the test vial with water from about 6 inches below the surface.
Add Reagents: Add specific reagents (like DPD #1) which react with bromine, turning the water color.
Color Matching: Compare the sample color against the provided color card in natural light for an accurate reading.
Adjustment: Based on the results, add more bromine or adjust the water chemistry if the level is too low or high.
Types of Kits
Liquid Kits (e.g., Hanna HI3830): Use reagents (like in Hanna Instruments) to provide high-precision measurements.
Test Strips: Convenient dip-and-read strips, such as AquaChek Red, which can test for bromine, pH, and alkalinity simultaneously.
Tips for Accuracy
If using a chlorine test kit for bromine, multiply the result by 2.25 to get the correct bromine concentration.
Read results quickly, typically within 15 seconds for test strips.
Test water regularly to maintain a 3–5 ppm range.
