JNW Direct Pool Test Strips 7-in-1 150 Pack — Fast 7-Parameter Water Test for Pools & Spas

JNW Direct Pool Test Strips are a 150-count 7-in-1 kit that gives quick color-based readings for pool and spa water chemistry in seconds.

Keep your pool or hot tub balanced without complicated equipment: these single-use strips measure key water parameters so you can react fast to changes. Each vial contains 150 strips calibrated to check seven common indicators, and the pack includes a color chart and a free e-book with practical maintenance tips. Designed for backyard pools, inflatable tubs and commercial spas alike, the strips let you monitor water quality on a simple schedule.

What does each test strip measure and why does that matter?

Each strip tests seven important factors that influence comfort, clarity, and sanitizer performance. Monitoring these readings helps you adjust chemicals before issues escalate, but these strips are a tool for routine checks rather than replacement for professional analysis.

• Free chlorine — helps track available sanitizer strength.
• pH — indicates acidity/alkalinity that affects sanitizer effectiveness.
• Total alkalinity — stabilizes pH to prevent swings.
• Hardness or calcium (if included) — protects surfaces and equipment.
• Other common parameters — help spot imbalances early.

How do I use these strips for fast, reliable readings?

Testing is straightforward: dip a strip briefly, wait the recommended time, and compare colors to the included chart. For best results, follow simple handling and timing steps and test the same spot in the pool or spa each time.

• Dip strip for about 2 seconds, remove and hold horizontally.
• Wait 30 seconds to allow color development before comparing.
• Match to the color chart in consistent light to read each parameter.
• Test twice weekly during high use or after heavy rain and chemical dosing.

How should I store and care for the test strips to ensure accuracy?

These strips are moisture-sensitive, so proper storage preserves accuracy and shelf life. Handle the vial carefully and avoid contaminating unused strips to keep results consistent.

• Keep the container tightly closed and store in a cool, dry place away from light.
• Do not touch the reactive pads on unused strips to prevent contamination.
• Use strips within 90 days after opening for best performance.
• Avoid storing near heat sources or inside humid areas like a pool shed without ventilation.
