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.

KEY FEATURES & BENEFITS

Laboratory-Grade Accuracy You Can Trust

Unlike generic drugstore test strips, LaMotte uses advanced reagent chemistry that delivers precise, consistent results. These are the same quality standards used in professional water testing laboratories.

4-in-1 Convenience

Why use multiple test kits when one strip does it all? Test chlorine, pH, alkalinity, and hardness simultaneously—saving time, money, and storage space.

Results in 30 Seconds or Less

Simply dip the strip in your water for one second, remove, wait 15-30 seconds, and compare to the color chart. No complicated procedures, no waiting around—just fast, accurate results.

Perfect for Hot Tubs & Pools

Whether you own a 2-person spa, a family-sized hot tub, a swim spa, or a backyard pool, these strips work flawlessly with all chlorine-sanitized water systems.

Compact & Waterproof Bottle

The durable, moisture-resistant bottle protects your strips and fits easily in your spa cabinet, pool bag, or service vehicle. The color comparison chart is printed right on the label for instant reference.

Cost-Effective Water Care

At 50 strips per bottle, you're getting exceptional value. Test 2-3 times per week for months without the expense of liquid reagents or digital meters.
