Sutro Smart Pool and Spa Monitor for Chlorine, Saltwater, pH, and Alkalinity Testing

Sutro saves you time and money. The app sends you quick readings 3x/day so you always know your exact pool chemistry. Never add in chemicals that your water doesn't need. All you need is a pool or spa and an internet connection for Sutro to work. Our device works great with chlorine, salt water, mineral, and bromine pools and spas. Today, you will purchase the Sutro Sytem for $499. Once you receive your device, you will be able to choose premium ($39/mo) or basic ($39/mo) service within the Sutro App. This includes the cost of monthly cartridges shipped to your doorstep. We're on standby. Sutro's success team is available at the click of a button to solve your water problems.
