Sutro Smart Pool Monitor: Hands-Off, Hassle-Free Water Testing That Works
Key Takeaways
- Sutro automatically measures pH, free chlorine (or bromine for spas), total alkalinity, and water temperature
- Reagent-based cartridges ensure high accuracy, with real-time results sent to the Sutro mobile app
- No test strips, no manual guesswork—just scheduled, data-driven monitoring
- App delivers precise chemical recommendations tailored to your pool or spa
- Ideal for homeowners who want convenience, reliability, and peace of mind
Traditional Pool Testing Wastes Time and Money
If you’re still using test strips or relying on vague color charts, you know the frustration. Manual testing is inconsistent. You guess how much chemical to add, hope it works, and repeat. The result? Wasted chemicals, cloudy water, and constant maintenance headaches.
Sutro eliminates the guesswork.
Our smart water monitor floats in your pool or spa, automatically testing your water up to three times a day. The readings go straight to the Sutro app—along with customized treatment advice to keep your water crystal-clear and safe.
What Sutro Measures
Sutro tracks the most important metrics for maintaining balanced pool and spa water:
- pH: Helps prevent eye irritation, corrosion, and scaling
- Free Chlorine or Bromine: Your primary sanitizer, monitored for safe disinfection
- Total Alkalinity: Stabilizes pH and prevents water from becoming corrosive or scale-forming
- Water Temperature: Affects sanitizer efficiency, swimmer comfort, and dosing recommendations
You don’t have to manually test anything. Sutro handles it on a schedule.
How Sutro Works
Sutro uses a reagent-based cartridge system, delivering the same type of high-accuracy testing you’d expect from a pool store, without leaving your home.
Here’s how it works:
- Drop the monitor in your pool or spa
- Connect it to the app
- Get lab-quality readings and treatment instructions, 1–3 times per day
- Follow the recommendations. That’s it.
You’ll never go back to guesswork.
Why It Matters
When your water chemistry drifts, issues follow...algae blooms, equipment wear, swimmer discomfort. Sutro prevents that by alerting you before things go wrong.
It’s proactive pool care, not reactive damage control.
Designed for Everyday Pool Owners
- No complex setup
- No calibration strips
- No recurring service visits
- No proprietary chemical lock-in
Use the chemicals you prefer. Sutro’s app adjusts the dosing advice based on your inputs.
What Sutro Doesn’t Do
Sutro doesn’t track ORP or offer indefinite battery life. It doesn’t claim to be "eco" by skipping recurring components...instead, it uses cartridges that ensure fresh, accurate testing every time.
If you need ORP tracking or prefer avoiding ongoing cartridge swaps, there are other products to consider. But if you want precision testing, proven results, and an effortless experience, Sutro is built for you.
