The Sutro Smart Monitor is a device to help you manage your pool (or spa). It's the simple, safe, and seamless way to measure, monitor, and get treatment recommendations to keep your water safe.
Long gone are the days when you struggled to figure out how much dry acid you needed, given your pH measurement on a test strip (or test kit).
Is it really as red as it looks?
I *think* so... meh, I'll just dump in more chlorine, wait I was supposed to throw acid in. Dang!
The Sutro Monitor and Hub give you the peace of mind. All you need to do is toss the monitor in your water, and the Sutro application will tell you what to do and when to do it. You can also scan in your UPC (barcodes) of chemicals you already have, and with our growing database of chemicals - we'll go one step further of telling you how much chemical of your chemical you should put in.
Read below for more details.
The Sutro Box comes with:
- (1) Sutro Monitor (this floats in your pool or spa)
- (1) Water test cartridge (measures pH, free chlorine (and bromine for spas), and alkalinity). It also works for salt water pools.
- (2) Rechargeable Li-Ion batteries
- (1) Hub and Charger base unit (this goes in your house to extend the Sutro's range)
- (1) US-110V adaptor
The Sutro Monitor
The Sutro Monitor is the piece that floats in your pool (or spa). The unit is about the size of your forearm. We've built it larger to make sure that it doesn't get sucked and stuck in your skimmer. The box comes with two rechargeable batteries, one is in the monitor (so it can have power), this gets swapped out once a month. The other battery remains to charge in the Hub & Charger unit, while the Sutro is the workhorse that tests your pool (or spa). We've also included a tether, you could tie it to something like a step-ladder, so it doesn't get in the way. Below are some more hero shots, we think it's pretty beautiful, the least to say.
Water Test Cartridge, Li-Ion Batteries, and Hub & Charger
The Water Test Cartridge
The cartridge is the heart of the Sutro system. It's a precision-built piece of (super small) technology that takes its queues from its much older and smarter brother in the medical industry, the ELISA microfluidic chip. This is why the Sutro technology is different than everything else out there. The cartridge system uses real reagents to measure water chemistry the same way you do. We measure pH with a .1 pH accuracy, free chlorine to a .2 ppm accuracy, and alkalinity in true mg/CaCO3. This means that we're actually doing the alkalinity test that we're all too lazy to do. And we count the drops pretty accurately. We've spent over 50,000 tests in swimming pools (and spas) around the USA to measure the accuracy of our color LED spectrum, and we'll keep getting smarter.
FYI - you'll change out the cartridge once a month, and we deliver those to you on a monthly basis.
Rechargeable Li-Ion Batteries
We needed to power the Sutro Monitor with something that would give us the conscience to know that we're not just throwing more batteries into the land-fill. That's why we had to try super hard to make sure that the Sutro unit was waterproofed, and the Hub & Charger was built as a charger too. There are two batteries in the box, so you can use one to power your Monitor, while the other charges. When it's time to change the cartridge, we've timed it such that the batteries can be swapped out too! We at Sutro definitely care about the environment and hope you do too.
The Hub & Charger
The Hub & Charger is exactly that, a hub and charger unit - combined. The base is command central for all the data coming to and from the Sutro Unit in your pool (or spa). We've also packed this hub with a ton of technology, we use 900MHz to communicate with the Monitor in your water, so it can surpass walls, distance, your cover, and the water. A little known fact about WiFi and Bluetooth is it's actually pretty bad around walls (and more importantly water). That's why you lose connectivity when you walk too far away from your phone wearing your bluetooth speakers. The 900MHz makes it possible for us to send small amounts of test data without needing to have a real high transmission rate. We're not sending YouTube videos to and from the Monitor, we're sending some water test data. The hub also connects to your in-home WiFi network, so think of it's left hand holding a 900MHz connection with the Monitor in your water and it's right hand holding onto your home WiFi connection to send all the information to your app.
The Sutro application is available both on iOS and Android. You can download either of them by going to this page. The Sutro App is jam-packed with features and where you'll probably be spending the majority of your time. The application has been built with simplicity in mind, we don't want you to focus on the details - but rather on spending more time in your water, knowing it's safe, and that Sutro has your back. If your water is good, we'll tell you that - to not clutter your screen with unnecessary details. If you're a geek like us, we still give you the option to dig in and see the pH, free chlorine, and alkalinity details. We've also tried to build prompts and reasoning for why you're doing something because the worst case is that we just tell you do something and you really don't know why.
With time, we'll make it better, faster, and stronger (with your comments and help, of course).
