Quick verdict
One of the more thorough smart monitors — three real parameters, automated, at a recurring cartridge cost.
Ideal for
- Owners who want automated alkalinity too
- Data-and-trends people
- Testing-averse owners
Not ideal for
- Cost-per-test minimizers
- Those fine with manual testing
The full picture
Sutro's floating device runs automated reagent-based tests several times daily for free chlorine, pH, and total alkalinity — more chemistry than most smart monitors — and sends trends and recommendations to an app. Like other smart monitors it runs on consumable cartridges, and the value depends on how much you dislike manual testing.
