Why Sutro is better: Built to Last

The Sutro Smart Monitor

Why Sutro is better: Built to Last

It Measures What Matters

The most important four measurements you can take for your pool are temperature, pH, Free Chlorine, and Alkalinity. Those four form the basis of determining the health of your water. Sure, there are a bunch of others (you’ll get 7-9 when you go to the pool store, except temperature of course) but for daily measurements to see how your water is doing, those four will give you all you need.

It Weighs Like 10 pounds!

The first thing you will notice when you hold a Smart Monitor in your hand is that it weighs a lot. Actually, it’s 4.85 pounds to be exact. The weight is to keep it upright in your pool but it’s also all those pumps to make sure we get a good sample of your water.

It’s as Big As Your Arm!

The smart monitor is big for a reason — we need to get an accurate sample of your water. It’s the same type of sample you’d get if you use a strip or reagent drop test. Recall that the instructions tell you to “take a measurement almost up to your shoulder below the surface of the water.” The reason for that is that anything shallower (between the surface and your arm depth, like 18 inches) will not be representative of your actual water chemistry.

Water near the surface has very different chemistry than below the surface. I’m sure you have seen that when you look at the surface of your water and sometimes see a sheen. That sheen can go deeper than the surface and can throw off your measurements. That’s why you have to take a sample deeper under the surface.

Reason #1: It’s built to last and that’s why we guarantee it!

It Takes 3 Measurements A Day

The smart monitor measures the temperature, pH, Chlorine, and Alkalinity of your pool three times a day. To date, we have taken those four measurements over 94,377 times in the pools we are monitoring.

If you realize that each measurement would take you 3 minutes (on average), that’s a total of 

283,131 minutes or 4,718 hours, or 196 days of measurements. 

All those measurements are fed into our recommendations engine to make it better every day. Sure, we’re not perfect yet but every day we (and our recommendations engine) learns how to treat your water better.

All that knowledge and data will save you not only money but a lot of time. That’s the time you can spend enjoying your pool.

Reason #2: More data that accurate = Better Recommendations

It Allows You to Use Your OWN Chemicals
