The Best Pool Thermometers: Digital & Wireless
Temperature Thermometers with String, Shatter Resistant, for Outdoor & Indoor Swimming Pools, Spas, Hot Tubs, Aquariums & Fish Ponds
By Allen Hayward
People have very specific demands when it comes to the water temperature of a pool. On the one hand, they may want to jump into a pool of cool water during the hot summer months. On the other hand, they may find it uncomfortable if the water is too cold because the sudden temperature change from hot to cold will shock their system.
If your pool has a heater, then you can heat the water just enough to make it comfortable without making it burning hot. The only way you’ll know the temperature of the water is if you use a pool thermometer to test it and give you an accurate temperature reading.
There are many benefits to using a pool thermometer. Let’s go over those benefits now.
Testing the Pool Heater
If you don’t have a pool thermometer, then you may have trouble determining whether your pool heater is working correctly. A pool thermometer allows you to see if the water temperature rises after you turn on the heater. That way, you’ll know if the heater is actually working or not. If you turn up the heat, and the temperature remains the same or gets cooler, then you’ll know that your heater is faulty.
Lower Your Power Bill
Swimming pools don’t need to be heated all the time, especially if you live in a tropical location or warm-climate region. If you can monitor the temperature of the water, you’ll know when it is a better time to turn off the heat or at least turn it down. Then you can reduce your energy consumption and save money on your energy bill at the end of each month
Better for Your Health
There are certain people who have their own pool temperature requirements due to health reasons. For instance, someone with multiple sclerosis cannot handle too much heat or else their symptoms will get worse. A pool thermometer allows you to set an ideal temperature for a person suffering from this condition. This will give them relief and joy when using the pool instead of pain and misery.
As for senior citizens and younger children, they would rather have warmer pool temperatures than cooler ones. To ensure that you don’t shock their system with cold water, you can make the temperature just warm enough for them to be comfortable in the water. A pool thermometer is the only way you can make this happen.
Types of Pool Thermometers
A pool thermometer may seem like a simple invention, but there are actually four different categories of pool thermometers.
Wireless Pool Thermometer
Wifi Pool Thermometer
Digital Pool Thermometer
Some of these categories can be combined. For instance, you could have a mercury-filled thermometer or digital thermometer that is also a floating thermometer. But if it is a handheld thermometer, then it can only be digital.
Mercury-filled thermometers are more dangerous if they’re floating in the water around other swimmers. Let’s say a swimmer accidentally damages the thermometer or bad weather damages it. The mercury inside the thermometer will pour out into the pool water. On top of that, you’ll have small pieces of glass in the water which could injure somebody or rip the liner of the pool.
Therefore, out of safety concerns, a digital handheld thermometer is the best choice.
There are endless numbers of pool thermometers available to purchase. How do you know which one is good quality and which one is not?
Milliard Outdoor & Indoor Digital Pool Thermometer
The Milliard digital pool thermometer works well and is very affordable. It can measure temperatures in the water ranging between -4°F and 158°F. The three-inch display screen is easy to read and will automatically shut off after three minutes. This will help you save energy on the 1.5V LR44 button battery in the device. The temperature continues to get measured, even while the thermometer is off. You’ll have an immediate readout of the temperature every time because of this.
The thermometer is designed to stay afloat on the water. However, a nylon cord that is 42 inches long comes with the thermometer in case you want to install it on the pool wall instead. The thermometer can also work well in hot tubs too.
Milliard Floating Pool Thermometer (Polar Bear)
Most thermometers look the same, but this particular pool thermometer looks like an adorable polar bear. The rope tether included lets you position the thermometer in the same area of the pool. You’ll get both a Celsius reading and Fahrenheit reading of the temperature.
The polar bear thermometer is filled with mercury, but the exterior is constructed from durable “acrylonitrile butadiene styrene” material. This is another way of saying ABS thermoplastic. With this material securing the mercury, there is a less chance of spills and leaks.
Ambient Weather Wireless 8-Channel Floating Pool Thermometer
This thermometer lets you see the water temperature of the pool while you’re indoors or outdoors. Thanks to the wireless technology integrated into the thermometer, the temperature reading can get wirelessly transmitted to more than 100 feet away on an LCD display screen. You’ll be able to place multiple sensors around your pool in 8 different locations. Then you can use the 8-channel system to check the temperature of each location in the pool. The entire thing runs on solar power, although you have the option to use four AAA batteries as a backup energy source. The temperature updates at 60-second intervals.
If you add chemicals to the water, remember to take out the floating thermometer first. Otherwise, the chemicals could greatly deteriorate the plastic of the thermometer.
Raytek Non-Contact MiniTemp Infrared Thermometer
This is a futuristic style thermometer which can measure temperatures ranging between 20°F and 932°F. You’ll have a huge backlit display screen which will give you immediate readings of the temperatures. The response time for each reading should be under 500 milliseconds.
The design of the thermometer is ergonomic, compact, and durable. It gets power from a 9V alkaline battery (included). To preserve its lifespan and prevent damage, you can put the thermometer in a storage pouch and protective boot (included).
Etekcity 1022D Dual Laser Digital Infrared Thermometer
The Etekcity 1022D is a handheld pool thermometer which uses infrared lasers to give you an instant temperature reading of the water. Not only that, but it will give you the temperature of virtually any area of the pool. To get the most accurate temperature, get a reading from the middle of the pool. After all, water depth always affects the temperature the most.
It comes with a 9V battery and a two-year warranty. It can give you temperature readings which range from between -58°F and 1022°F. Of course, you’ll probably never need to see a temperature greater than 120°F in the water (hopefully not). However, you can use this device for other things too, such as car maintenance, home repairs, and barbeques.
With a pool thermometer, you’ll never need to guess what the temperature is again before jumping into the water. Now you’ll have complete control over the temperature by using the thermometer and heater together.
