The outer core has a double-wall, so it fills upto keep your Sutro buoyant, like a submarine.

3. Waterproofing

The Sutro is built as a cylinder, and we’ve built a radial seal to confirm that no water gets inside while it’s testing.

How Does It Work?

The Sutro Smart Monitor is a revolutionary device that simplifies and streamlines spa maintenance. It works by measuring the pH, chlorine or bromine, and total alkalinity levels three times a day. The Sutro monitors your spa water using liquid reagents, the same as those used in traditional at-home test kits or spa stores.

The monitor then sends the readings to the Sutro mobile app, which provides you with daily reports on your water chemistry. It also recommends precisely what and how much of each chemical you should add to keep your spa safe.

The Sutro Smart Monitor is an excellent solution for spa owners looking to save time, reduce chemical usage and maintain a clean and clear spa at all times.
