Our 3-in-1 pool test strips simplify daily water quality monitoring for swimming pools, hot tubs and spas, measuring free chlorine, pH and total alkalinity in one single test strip. Just dip the strip into pool water for 1 second, shake off extra water, then compare color pads with the printed color chart to get readable results within 30 seconds. No messy liquid reagents, extra tools or professional operation needed.

Made of high absorbent filter paper with stable reactive coating, the strips produce bright, distinct color changes without blurring, ensuring stable and accurate readings. Stored in an airtight plastic bottle, it effectively isolates moisture and dust to extend shelf life and avoid invalid tests. Compact and lightweight, easy to carry for outdoor pool maintenance.

Perfect for household above-ground pools, inground pools and jacuzzis. Regular testing helps you adjust pool chemicals properly, keep water balanced, avoid cloudy water, skin itch and pool equipment corrosion. Cost-effective and user-friendly for home pool owners and casual maintenance workers, every batch is strictly inspected to deliver consistent, reliable testing performance.
