Which Pool Water Testers Are Best? [Expert Guide!]

Spread the love

Knowing which type of pool water tester is best can be a little confusing. There are several different makes and models to choose from when preparing to purchase a device designed to measure the purity of the water in your pool. The key issue to consider when selecting a pool water tester is which type of technology is most suitable for your needs. Below, you will discover a guide that can assist you in making the right decision. Be sure to keep reading as we dive into the best pool water testers on the market.

PEMF Testing

If you are looking for a device that can test for radiation and there is no option on the market that fits perfectly, then you should consider purchasing a Pulse Electric Magnitude Field tester (PEMF tester). This style of tester mounts on the wall above the pool and sends out electromagnetic waves into the water. When a harmful element is found, the tingling sensation that you feel is enough to let you know that you have a problem.

This type of pool water tester is better suited for commercial pools as it does not require any chemical reactions to determine the presence of a contaminant. The lack of chemicals means that it is much less likely to deteriorate over time and thus provide false results. In addition, this type of tester can measure the electrical activity of the water in your pool which determines the amount of radiation present. To learn more, visit https://repairpal.com/.

Fluoride Testing

Fluoride is a naturally-occurring substance found in groundwater and many types of fresh water. It is extremely toxic to humans and has been known to cause dental and skeletal fluorosis. This condition can cause tooth discoloration, aching, and eventually loss of teeth. To reduce the risk of fluorosis, you should always choose water containing less than 1.45 ppm of fluoride. You can purchase a water quality monitor that is specifically designed to check for and alert you of fluorides in water at https://repairpal.com/.

This type of tester is great for use in pools as it only requires a few simple steps to operate. First, install the sensor at the deepest point of the pool. Next, add a few drops of liquid into the tank. After this, you can turn the device on and walk away leaving it to do its work. When the results are displayed on the display, you will know if there is too much fluoride in your pool or not.

This type of device is more suitable for home use as it is lightweight, portable, and easy to use. However, if you decide that traveling with it to your pool is not convenient, then it may not be the best choice for your needs. In addition, this type of tester is not designed to detect the level of radiation in your pool so you will need to purchase an additional monitor for that purpose.

Radium Testing

Radiation is everywhere around us and can be found in the soil, in the air, and in many forms of water. Although it can be harmless, when it comes to medicine and science it can be considered very dangerous. There is some risk involved with this type of activity, and thus you should always assume that every time you are exposed to radiation, there is some risk involved. To determine the amount of radiation that you are exposed to, you can purchase a Geiger Muller counter at https://repairpal.com/ that will monitor and alert you whenever there is a spike in radiation.

The good thing about this type of tester is that it is very easy to use. Simply place the probe into the pool water and wait for the results to be displayed on the device. To take a deeper dive into this type of testing technology, visit https://en.wikipedia.org/wiki/Geiger%E2%80%93Muller_counter.

Chemical Testing

Chemical testing is typically used in combination with water testing to determine the specific ingredients in the water. Typically, you will need to purchase separate equipment to perform the chemical analysis of the water, and thus having a tester that can perform both functions is ideal. To test for the presence of nitrates, nitrites, chlorides, phosphates, and chloramines, you can purchase a Total Acidic Nitrogen tester at https://repairpal.com/.

The advantage of this type of tester is that it can analyze multiple chemicals at once which saves you a great deal of time. In addition, some models can even analyze the chemicals in your pool without you having to enter the water so you can get an accurate reading without having to fish around in the pool for a sample.


A multi-use tester is ideal if you have more than one type of pool. For example, if you have an above-ground pool and a crawl space pool that need testing, then you should purchase a tester with two separate chambers so that you can perform the analysis for both pools. When selecting this type of tester, make sure that you purchase one that has the capability of analyzing the chemicals in your pool without having to remove the device for maintenance or servicing as removing the device once it is installed is very difficult and can cause serious damage to your pool.

Some multi-use testers are more sophisticated than others and come with many additional features. For example, some models can test for specific harmful chemicals or elements and also provide a visual alert through a system of lights and/or alarms. Some models can even be integrated with a security system so that if movement is detected then an alarm can be issued and those responsible can be punished according to law.


The type of pool water tester that you select depends on your specific needs. If you are looking for a quick, easy, and most importantly, reliable method of testing for the presence of radiation, then you should purchase a Pulse Electric Magnitude Field tester (PEMF tester). This type of tester is considered the ‘gold standard’ when it comes to measuring radiation and can detect even the tiniest amounts of radiation present in the water. The fact that it is chemical and radiation-free means that it is less likely to provide false results over time.

If, however, you have a pool that you want to test for fluoride or other chemicals, then you should consider a multi-use tester as they can analyze multiple chemicals at once and provide a more reliable result. In addition, if you want to test for specific elements, then you should opt for a specific model sold for that purpose.

Where Can I Buy A Pool Water Tester?

If you are planning on purchasing a pool water tester, then you should first check with your local retailers to see if they carry this type of equipment. Many stores, including hardware and grocery stores, sell water testing equipment, and thus if you can find a good deal at a retail store, then it may be worth buying it there rather than trying to find a laboratory that carries this type of product.

If, however, you decide that buying a tester at a retail store is not ideal because you want to ensure that you purchase an authentic product that has not been tampered with, then you should look for a laboratory that specializes in this type of testing as they can provide an authentic product that has not been tampered with. In some instances, they may even have samples of the product that you are purchasing so that you can confirm that it is exactly what you want. If, however, you want a quick and easy method of testing, then you should opt for a model that can be used for multiple pools as they are much easier to use than others and do not require much maintenance.


As a general rule of thumb, you should perform regular maintenance on all of your appliances and devices that are connected to or near water. This includes the filters, chemical additives, and pumps in your pool. When it comes to your pool, you should change the water chemistry every three months or every six months depending on the size of your pool. This ensures that the water is always fresh and that no bacteria or algae are growing in the pool that can cause serious harm to you or your family.


In the end, what is most important is that you select a pool water tester that will provide you with the results that you want and need without the fear of using unreliable equipment.
