Why Do You Need a Pool Thermometer?
As I describe above, the inappropriate temperature of your pool water might badly affect your body’s health. But how? Now I will talk more specifically about it.
While cold water (normally lower than 60°F) might lead to cold shock if in prolonged use, unnecessary warm water (normally higher than 90°F) might cause your body to release sweat and lead to dehydration, even cramps, and muscle spasms.
Your pool contains lots of different chemicals that need to be maintained at a balanced level to keep your pool water hygienic, clear, and healthy. A water test kit or a pool test strip might be useful to help you determine the chemical levels of your pool.
Then you need some types of pool cleaners to remove unwanted chemicals at high levels or, in contrast, some floating pool dispensers to add chemicals at low levels, such as chlorine, bromine to your pool water.
But there’s one thing you might forget, the water temperature also affects your pool chemical levels and then indirectly have influenced your body’s health.
While chlorine in your pool is responsible for killing harmful bacteria and algae to keep your pool hygienic, heat is one of the main factors which might decrease chlorine’s effectiveness. Warmer pool water will burn through its chlorine supply as well as breeds more bacteria.
Not to mention warm water is such a perfect environment for algae to set up its camp. You never want to jump into a green-water pool, right?
That’s why you definitely need to grab this small piece of equipment for your pool, not only for your health purpose but also for your best comfort in the water.

Pool Thermometers Buying Guide
There are some main technical features you need to keep in mind to purchase a pool thermometer, which satisfies all your expectations. Let my buying guide below give you a hand for the best suitable one.
There are two main types of pool thermometers, including digital model and analog model. Each of them has its own benefits and drawbacks.
Analog pool thermometers are the basic type with the same operating mechanism as an ordinary indoor thermometer. It contains a thin strip of plastic (or glass) and mercury (or alcohol) inside.
Floating thermometers are the most common type of analog thermometer. However, an analog thermometer can be designed either floating or hanging (submerged underwater with a strip attached to the side of the pool).
These thermometers are cheap, easy to use, and potentially durable over time (better durability than digital thermometers). However, they are not appreciated in terms of accuracy and convenience.
Meanwhile, digital pool thermometers are the most popular type among users, thanks to their advanced technology. A digital thermometer can be either floating, hanging, or handheld (wireless).
The temperature number of your pool will be displayed on a separate display console, which is super easy to read. It won’t take your time to identify the mercury level in an analog-modeled thermometer.
Besides, you won’t need to worry about incurring problems with the mercury inside pool thermometers, which could be damaged by direct sunlight and pose deadly health problems to our health.
However, digital thermometers relatively come at high prices.
As I mentioned above, an analog thermometer might be more suitable for long-term use. Still, the material might decide the lifespan of your pool thermometer.
Cheap, thin, easy-broken materials will not only reduce the long-lasting capacity of your thermometer but also implicit risks of damaging when using and threatening your health safety (especially in analog thermometers).
Moreover, well-known brands might ensure a reliable product with excellent durability. If you shop online, visit verified online stores not to get cheated with a crappy product working for a few days.
A warranty paper from the manufacturer is also needed for the sake of the product failure (commonly one-year warranty).
Analog thermometers don’t need batteries to function while digital thermometers are either battery-powered or solar-powered.
Solar-powered thermometers are eco-friendly because they harness power from the sun to power its own unit. They might be a bit more expensive than battery-powered ones, but in the long run, they will save you a great amount of money for replacing batteries regularly.
Battery-powered thermometers are the basic version but probably less common now. They require frequent battery replacement to stay alive though you can cut down on the expense for using rechargeable batteries.
