The convenient, low-profile design ensures it’s always within reach when I need to check the water temperature, and the quick and easy installation makes it a hassle-free choice for anyone looking to enhance their pool or spa experience.

One thing that stood out to me was the battery life. The sealed internal, non-replaceable AA alkaline battery ensures that you won’t have to worry about changing batteries often.

Buyer’s Guide

Heating your pool to the perfect temperature is essential for maintaining a comfortable and enjoyable swimming experience. However, finding the right pool thermometer can be a daunting task. This buyer’s guide will help you understand the key features, considerations, and advice for choosing the best pool thermometer for your needs.

Important Features to Look for in a Pool Thermometer

When selecting a pool thermometer, consider the following features to ensure you get the most accurate and reliable readings possible. These include the type of thermometer, its construction, and additional features it may offer. Some factors to ponder include digital accuracy, float quality, ease of reading, battery life, durability, and water-resistance.

Choosing the Right Type of Pool Thermometer

There are three main types of pool thermometers: manual, digital, and automatic. Manual thermometers require a user to read the temperature by examining the temperature scale, while digital thermometers use an electronic display for easier reading. Automatic thermometers may use solar power for charging or rechargeable batteries to maintain continuous readings. Each type has its advantages and disadvantages, so it’s essential to consider how frequently you’ll check the temperature and your preferred reading method.

Considerations for Pool Thermometer Accuracy

Since pool temperature can vary due to factors such as weather, chemicals, and bather presence, it’s vital to have an accurate reading. Factors determining the accuracy of a pool thermometer are the accuracy of its scale, responsive elements, and calibration. Choose a thermometer with a high-accuracy scale, a responsive element, and a secure calibration, ensuring your pool water is measured accurately.

General Advice for Selecting a Pool Thermometer

While choosing a pool thermometer, consider the type of pool you own, whether it’s an above-ground or in-ground pool. The location of the thermometer probe can affect its accuracy, so choose a site where you can easily see it but avoid obstructions. Another crucial aspect is the thermometer’s durability since it will be frequently exposed to harsh pool environments. Lastly, the ease of installation is essential. The thermometer should be easy to install and remove, so it doesn’t hinder the enjoyment of your pool.


What is a pool thermometer?

A pool thermometer is a device used to measure the temperature of the water in a swimming pool. It is essential in maintaining an ideal water temperature for swimming, which is typically between 78–82°F (25–28°C). Depending on the pool thermometer type, it can be submerged, float on the water’s surface, or attached to the pool’s side.

Some models also feature additional features, such as a digital display, alarm systems, or the ability to connect to a smartphone app for remote monitoring and temperature adjustment capabilities. Overall, a pool thermometer is a valuable tool for pool owners to ensure a safe and comfortable swimming experience.

What are the different types of pool thermometers available?

There are three main types of pool thermometers, each with its advantages and limitations: Manual pool thermometers, Digital pool thermometers, and Smart pool thermometers. Here’s a brief overview of each type:

  1. Manual pool thermometers are typically inexpensive and require manual insertion into the water to read the temperature. They may not be as accurate as other types, but their simplicity makes them a popular choice for budget-conscious pool owners.
  2. Digital pool thermometers provide more accurate readings and usually come with a probe that is inserted into the water. They often feature a wireless display that can be mounted nearby for easy viewing. Some digital pool thermometers also have the ability to store historical temperature data and provide alerts when the water temperature rises or falls beyond a specified range. 3) Smart pool thermometers are connected to a smartphone app, which allows for remote monitoring and temperature control. They often come with advanced features such as predictive algorithms to suggest the optimal time to turn on a pool heater or cooler to achieve the desired temperature.

How do you use a pool thermometer?

The process of using a pool thermometer varies depending on the type of thermometer you choose. Here’s a general guide for each type:

  1. For manual pool thermometers, insert the thermometer bulb into the water, making sure it is fully submerged. As water temperature influences temperature readings, wait for the thermometer to settle and read the temperature. Most require no shaking or stirring for an accurate reading. Once you have the temperature, remove the thermometer from the pool, and note the value.
  2. For digital pool thermometers, insert the probe into the water so that it is fully submerged. Turn on the device and wait for the temperature reading to update and stabilize. Most digital pool thermometers have a waterproof, wireless display that can be mounted near the pool. Consult the manufacturer’s instructions for any additional setup or configuration needed.

What should be the ideal pool temperature?

The ideal pool temperature varies depending on the users’ preferences and the predominant climate in the area where the pool is located. In general, a temperature range of 78–82°F (25–28°C) is considered comfortable and suitable for most swimmers. However, some may prefer a slightly higher or lower temperature, especially children, older adults, or individuals with certain health conditions. Consult your local health department or the CDC for more specific temperature guidelines.

If you’re concerned about safety, particularly for young children, consider using a pool thermometer with preset temperature alarms to ensure the water remains within a safe range. Pool thermometers can also help prevent overheating or freezing of the pool water, which can affect the pool’s overall health, chemical balance, and functionality of pumps and filters.

What are the benefits of using a pool thermometer?

Using a pool thermometer offers numerous benefits to pool owners, including:

  1. Maintaining a safe and comfortable water temperature for swimming, which can help prevent overheating or hypothermia, especially for children or elders who may be more sensitive to temperature changes. 2) Ensuring a consistent water temperature for recreational activities, such as diving or playing water sports. 3) Monitoring the pool’s temperature before and after using it, providing valuable insights for adjusting heating and cooling systems, ensuring the pool remains in optimal condition throughout the season.
  2. Using a digital pool thermometer with a wireless display allows pool owners to keep an eye on the temperature from a distance, eliminating the need to frequently check the pool’s temperature. 5) Smart pool thermometers with connectivity to a smartphone app enable pool owners to monitor and control the temperature remotely, providing convenience and peace of mind, especially for those with busy lifestyles. Overall, pool thermometers contribute to a safe, comfortable, and enjoyable swimming experience.

Can a pool thermometer be used for both heating and cooling?

Yes, a pool thermometer can be used for both heating and cooling purposes. Its primary function is to monitor the water temperature and provide accurate readings to help pool owners make informed decisions regarding adjusting the pool’s temperature. For heating, the thermometer can be used to check if the pool heater is reaching the desired temperature and to avoid overheating the water. For cooling, it can be used to monitor the water temperature and identify when the pool is approaching the desired temperature for cooling.

With the help of a pool thermometer, pool owners can ensure that the pool’s temperature remains within the desired range, regardless of the season or weather conditions. This can be especially useful in areas with extreme temperature fluctuations or during times when the pool is infrequently used, as it helps maintain the pool’s optimal temperature for future use. By effectively managing the pool’s temperature, a pool thermometer contributes to a more enjoyable swimming experience and a healthier pool environment.
