If you have a swimming pool, the chances are that you have climbed into it at some point and thought the water was either too cold or too warm.
To help you avoid that situation, you may want to tune in to your water temperature with a wireless pool thermometer. There are a wide variety of wireless pool thermometers that are available for purchase. So, it can be pretty hard to determine what the best wireless pool thermometer is for you and your pool.
So we’ve done the work for you, testing many products to try and find the best pool thermometer.
When it comes to the temperature of a swimming pool’s water, we all have our preferences. Some people might like the water fairly warm, while others will prefer much lower temperatures. If you have a spa, you might even like the water hot, but that means you have to be careful to avoid overheating it and hurting yourself.
On really hot sunny summer days, most kids don’t care what the temperature of the water is.
But, their parents don’t want them climbing out shivering with blue lips. Knowing the exact temperature of the water is a good tool for parents, swimmers, and owners.
It can’t hurt to know the temperature of your pool’s water. But when it comes to wireless thermometers, there are various options tailored to different uses and applications.
Even among the best wireless pool thermometers, there is quite a variation and features. For instance, some thermometers are electronic with a digital display and a solar-powered battery. Other thermometers are simple analog devices that float in your water and do not have a remote display.
Let’s dive a little bit deeper into exploring the best wireless pool thermometers. Please forgive the pun!
Ambient Weather WS-14-X2 Wireless 8-Channel Floating Pool and Spa Thermometer with Two Remote Sensors – Best Overall
The WS-14-X2 is a top model wireless pool thermometer. It comes equipped with two remote sensors, and up to six additional sensors can be added to the system. You can monitor the temperature in your pool or your spa with the WS-14-X2 system.
And if there are other locations around your property that need monitoring, they offer a suite of other sensors that can measure temperatures.
Each remote sensor can be calibrated for accurate readings and synced on various channels to ensure reliable readings at the base station console, even if there is some interference. The remote sensors require three AAA batteries which you will have to purchase separately, but the base station comes with an AC adapter so you can plug it in.
Alternatively, you can stick with batteries, so it doesn’t need to be near a wall outlet.
The range of the remote sensors is up to 300 feet in ideal conditions, and you can expect it to work up to 100 feet even if there are some obstructions between them and the base station.
The reading on the base station is updated every 60 seconds. The console has a scrolling mode that flips through all of the available sensor information, displaying each sensor’s reading every five seconds.
If contact between the remote sensor and the console is lost, it is relatively easy to resync them.
The console also has enough memory to remember recent minimum and maximum readings, and you can also set audible alarms for low and high readings.
The scroll mode on the inside console is particularly useful. It allows you to see all of the sensors on your system without pressing any buttons.
The floating sensors come equipped with a small solar panel backed up by three AAA batteries. The sensors feature an innovative screwed-on lid design with an internal gasket to help prevent leaks. The sensor comes with two special wrenches to help you open the sealed canister when you need to change the batteries.
Aquatix Pro Premium Water Temperature Thermometers – Most Reliable
The Aquatix Pro Premium thermometer is shatter-resistant and equipped with a string for securing it to your pool’s ladder or another feature so that it is tethered and easy to read without having to get in the water to retrieve it.
It is designed for use in outdoor or indoor swimming pools, spas, hot tubs, fish ponds, or aquariums. Anywhere where there is water, this floating analog thermometer can tell you the temperature.
This thermometer is a common sight to see in backyard pools, and it is simple and fairly popular.
It doesn’t have a fancy remote sensor, but that means it doesn’t require batteries, syncing, or any electricity at all. It is a simple analog floating thermometer capable of reading up to one- hundred degrees Fahrenheit and forty degrees Celsius. You should remove it from the water if there is a chance it will freeze.
Aquatix has a satisfaction guarantee of one year on all their products. If you’re not satisfied, they claim they will refund the full price, no questions asked.
If you’re curious, the strength is 48 inches long. So you can let it float out into the water pretty far, but you can still just grab the string and drag it to the water’s edge for a reading.
Swimline 9250 HydroTools Solar Powered Digital Pool and Spa Thermometer – Honorable Mention
The Swimline 9250 HydroTools thermometer is appropriate for use in a swimming pool or spa. It is solar-powered, and it comes equipped with a nylon cord for securing it in place while it floats in the water.
It can read Celsius from zero to fifty degrees and Fahrenheit from thirty-two to over one hundred degrees. It is easy to reconfigure its easy-to-read digital display for either Celsius or Fahrenheit with the press of a button.
It has a digital display, but it runs on solar panel power. There is a small, rechargeable solar battery inside of the sealed device. In order to make sure that there is enough energy to give you a reading when you need one, the display shuts off when not in use.
To obtain a temperature reading, you have to press the button and activate the device. This feature extends the battery life significantly, but it is a little bit of a hassle. The digital display is cool but not really necessary.
Aquatix Pro Cool – Best for Kids
The Aquatix Pro Cool thermometer is an analog floating thermometer that reads Celsius and Fahrenheit accurately.
It is shatter-resistant and intended for use in pools, spas, Jacuzzis, hot tubs, and even aquariums. It is easy to use with a clear tube thermometer display, just like the Pro Premium model from Aquatix. It simply floats in the water.
Unlike digital models, there is no fancy display screen, and you can’t obtain a temperature reading remotely.
Instead, you have to physically read the thermometer. But it comes with a string for securing it to either a ladder or other piece of hardware for easy access.
This particular model thermometer comes with a yellow rubber duck on top.
It makes this thermometer something that looks fun as it floats and is appealing for kids. Some adults might even enjoy the fun factor and think that seeing a cute rubber duck floating in the water is preferable to looking at a piece of plain equipment.
This thermometer is a little bit different than all of the other ones we have reviewed so far. The laser grip 1022 is a non-contact, handheld thermometer. It uses a laser to read temperatures without touching the item that is being measured.
A nine-volt battery comes with the thermometer and provides a power source. You can measure a surface temperature from well below freezing to extremely high temperatures, in both Fahrenheit and Celsius. Hopefully, your pool never reaches five hundred degrees. But, it might come in handy to have a tool that can tell you the temperature of the water in your swimming pool or your BBQ or smoker.
It is very precise and accurate. It also takes readings very quickly, but it is mostly limited to getting a reading from the surface of what you aim it at.
By holding it about fourteen inches away from your water’s surface and then pressing the trigger, you can get an accurate reading of the surface water temperature in your pool instantly.
By moving around a bit and aiming it at different parts of your water, you might be able to find more accurate readings instead of just measuring the surface. For instance, if you have a return jet, you may be able to shoot the thermometer right at that jet and determine the temperature of the water coming in as it is circulating through your filter system.
This ability to take precise, rapid readings in a variety of locations could help diagnose a problem with your filter or heater. And it might be useful around the house as well.
When you’re buying a wireless pool thermometer, it’s important to look for one that does what you need it to. But you don’t necessarily need a lot of bells and whistles.
If you are only going to be checking the water temperature on your way into the pool, and it is only a short walk from your back door to the water, you might not mind walking over to the pool to see a floating analog thermometer.
But if your pool is a significant walk away from your house, or if you might not even go swimming if the water temperature is less than ideal, you might enjoy the functionality of a remote display.
This configuration allows you to see the temperature from inside your house, meaning you don’t need to get a towel and swimsuit ready until you know the water temperature is where you want it.
A thermometer with a digital display is typically going to be more expensive than a simpler analog model. And, where there is a digital display, there is a requirement for power.
That means a battery, maybe a solar panel, and the risk of electronics getting wet. The added expense and the hassle of battery changes might prove to be too much for some of us.
Keep it Simple
The best wireless pool thermometer is the one that meets your demands with the simplest design and easiest maintenance.
You’ll need a thermometer that is tough enough to stand up to the water, the sun, and the chemicals in your pool water. So, if you know your kids are going to be rough-housing, diving with the thermometer in their hands, and subjecting it to other abuse, maybe go with the cheapest option.
