The test kit — small plastic case with reagent tablets, test vial, and color comparison chart. Practical, pocket-sized.
Free Chlorine Test Kit (50 tests)
Kit de Prueba de Cloro Libre (50 pruebas)
Track your water's disinfection window
DPD reagent-based test kit that measures free chlorine residual in your cistern water. Test immediately after pipa delivery to confirm chlorinated source water, then track how fast chlorine decays over the following days. When chlorine hits zero, your water has no active disinfection protection. 50 tests per kit — enough for 6+ months of regular monitoring.

Why This Matters
Chlorine is the only active defense your cistern water has against bacterial growth. After a pipa delivery of chlorinated water, the chlorine residual decays over days — faster in warm water (Cabo’s ground temperature: 25-28°C year-round). Once it reaches zero, your stored water has no disinfection protection.
This kit lets you measure that decay curve for your specific cistern. Test right after delivery (should show 0.2-1.0 mg/L if the source was treated). Test again at day 2, day 4, day 7. You’ll see exactly when your protection window closes — and know how your cistern’s water age translates to real health risk.
