Why Choose Nixie Water Test Strips?
- 16 Parameters in One Dip: High-sensitivity imported reactive reagent coatings detect pH, free chlorine, total chlorine, hardness, cyanuric acid, lead, mercury, copper, and more — all from a single test strip, saving you the cost of multiple separate testing products.
- Results in 30 Seconds: Simply immerse the strip in water for 2 seconds, remove it, wait 30 seconds, and compare the color pads to the calibrated color reference chart. No professional equipment needed.
- High-Precision Color Chart: Anti-fade, UV-resistant ink printed on the bottle label ensures all color blocks are strictly calibrated to international standard concentration values — minimizing result misreads.
- Eco-Friendly PVC Base: Stable PVC material prevents reagent leakage and degradation; a biodegradable PLA option is also available for low-carbon, environmentally conscious use.
- Long-Lasting Sealed Packaging: Food-grade plastic bottle with aluminum foil inner lining and tight screw cap isolates moisture, dust, and light — preserving reagent activity for an unopened shelf life of up to 24 months.
- Non-Toxic & Non-Corrosive: Mild reagent coating is safe to handle; no complex steps, no harsh chemicals, and no professional background required.
