LaMotte® Insta-TEST® 4 Plus Spa Test Strips - 50 Count
LaMotte has been the gold standard in water testing for over 100 years, providing precision instruments to laboratories, municipalities, and water care professionals worldwide. The Insta-Test 4 Plus brings that same professional-grade accuracy to your home spa or pool.
Each test strip measures four essential water chemistry parameters in just 15-30 seconds:
- Free Chlorine (0-10 ppm) – Confirms proper sanitizer levels to eliminate bacteria and contaminants
- Total Alkalinity (0-240 ppm) – Stabilizes pH and prevents corrosive or scaling conditions
- pH (6.2-9.0) – Ensures water comfort and optimal chemical effectiveness
- Total Hardness (0-800 ppm) – Protects equipment from scale buildup and corrosion damage
With 50 test strips per bottle, you have enough for months of regular testing—ensuring your water stays balanced and inviting all season long.
