Best Pool Thermometer Buying Guide
Even though we have coveted the top seven best pool thermometers of 2021 for you to pick from, knowing about the key features to check out should make your search easier.
Of course, you may have a few customized requirements, but overall it’s essential to consider the following aspects.
Durability
Ideally, your pool thermometer should last for seasons together. Fortunately, most pool thermometers don’t have a short lifespan, even though many pool fittings do.
Ideally, look for a thermometer that features a simple design to withstand heat and other issues common in a pool. It should be easy to maintain for several seasons.
Power source
Though initially, the power source may not seem like a great deal, however, you will feel differently about it once you start using the unit.
Thus, to avoid any laments later, consider the power source seriously.
Analog thermometers, for example, will have low maintenance since they don’t have any power source. All you need to do is put it in the pool and forget about it.
Digital thermometers, however, require some work. These are generally battery or solar-powered, so it will require some work on your part for its upkeep.
Generally, your choice would be between solar and battery-powered thermometers.
Of course, each has its pros and cons.
Battery-powered thermometers must be charged using a unique tool. And there might be no signal to show that the unit is about to die.
Solar units naturally require sun exposure to function. However, it’s crucial to find a unit that will require minimum sun exposure to operate. Or you can also opt for one with power storage so that you can still get readings on a cloudy day.
Ease of use
A pool thermometer should not be too complex to use. Its job is simple and should require minimum effort from your end.
Keeping that in mind, you should not be required to move, clean, or adjust the thermometer continuously. Doing these would not be easy, so look for a unit that will give the readings without any issue.
Ideally, look for a unit that will nicely float if they are of the floatable kind or digital to ensure that they don’t have many complex features and unnecessary instructions.
The display should be easily readable without using a flashlight or making a mess.
Accuracy and consistency
The sole purpose of a thermometer is to get an effective temperature reading. Thus it’s ineffective to get a thermometer that does not provide an accurate reading.
However, be prepared to get some variation in the reading since accurate reading requires calibration, which isn’t easy.
Thus, instead of depending solely on the accuracy, it’s essential to consider consistency as well.
If you are aware that your thermometer constantly predicts a five-degree off reading, you can gauge the accurate temperature. On the flip side, if you get a unit that reads varied accuracy every time, then it’s not effective at all.
Thus, overall consistency is more essential than accuracy. Therefore opt for a unit that features stable consistency.
Warranty
When it comes to purchasing a thermometer, make sure you look for a unit that features a strong guarantee. Going wrong with your choice is highly probable, and if that happens within a few years of the product’s lifespan, a warranty will cover it.
In the absence of a strong guarantee, you might have to cover the replacement and repair costs of the thermometer in case something goes wrong.
Anything might go wrong at any time, especially with an attachment that is connected to the water at all times.
Most pool thermometers come with a guarantee. Even if a company provides a guarantee only on the components, you will still save a lot.
Display
A thermometer is no good if it’s difficult to note its readings.
Do note that each brand has a different display. They might vary in size; while some may be brighter, others might have backlighting.
So, to see which works best for you, check out the display before you decide. While buying from a store, you can always ask the salesperson to give you a viewing; however, check its display look on YouTube prior to taking a call if you are buying online.
This especially goes out to the people who suffer from vision problems.
In addition to the display, you also need to figure out whether you will like a wireless version with a display you can set aside.
Though it’s not essential, these can be effective if you are waiting for the pool to reach a specific temperature.
Frequently Asked Questions (FAQs) About Best Pool Thermometer
As the name suggests, the primary purpose of a pool thermometer is to monitor the pool temperature and has multiple benefits. For instance, if the pool water is too cold, over 60 degrees Fahrenheit, swimming in such water can lead to cold shock.
Besides, a pool thermometer allows you to save money and power by monitoring the pool temperature. Once the pool reaches the required temperature, you can turn off the heater, which is quite cost-saving. A pool thermometer is also practical during maintenance and pool calibration.
Temperature affects your pool water in multiple ways. For instance, during the summer months, rising temperature makes chlorine disappear quite quickly. The sun’s UV rays impact the chlorine, breaking it down and affecting the water quality.
Even heavy rainfall can affect the water’s quality as rainwater contains dirt and bacteria. These too attack the chlorine making the water quality poor.
Ideally, there are two types of pool thermometers, digital and analog. These can be further divided into floating, hanging, and handheld.
Of these, the digital models are the most effective and provide an accurate reading. Besides, they also have more additional features. However, they are a tad bit more pricey than the other units.
The analog models though cheaper than the digital counterparts and easy to use, are not accurate.
The same applies to the floating and handheld models. In comparison, floating thermometers are less accurate than hanging pool thermometers. Since the latter is not submerged in the pool like the hanging models, they often fail to provide the correct accuracy. Handheld ones are better than floating and hanging thermometers.

Indeed you need a pool thermometer.
Your pool temperature is undoubtedly going to affect your swim. Either it can be comfortable and relaxing or nerve-wracking and taxing.
And yes, the best pool temperature of 2021 has a role to play in that.
Additionally, whether or not your pool will be bacteria-infested will be determined by the water temperature.
So, you see, a lot depends on your pool water temperature. Thus choosing the best pool thermometer is essential. Fortunately, making that choice is not so hard.
We have covered the best products in the market to help you make a pick.
However, if you are not sure about the high-end digital thermometers, opt for the sole analog ones initially.
