Pool Test Kit/Digital Pool Tester Buying Guide

Owning a sparking swimming pool may be the ultimate dream, but maintaining its sparkling state is a tough task. You have to be particular about its cleanliness as well as sanitization so that it does not become a source of diseases and infections.

For this purpose, you need to use some chemicals; however, balancing these chemicals is also important. And a pool test kit or digital pool water tester can help you with that. Here’s a buying guide to help you find the right one.

Types of Water Testing Kits

Poolmaster Essential Collection Chemistry Case (22260) 5-Way Swimming Pool & Spa Water Test Kit, Small, Neutral

Pool Test Strips

Pool test strips are the easiest, quickest and cheapest way to test your pool water. They are fairly accurate but not as precise as liquid and digital test kits.

Test strips come with a color chart that you match the strips to.

This gives you the pH, alkalinity or acidity level. You can also use strips to test for specific chemicals like chlorine, bromine or water hardness.

You can buy strips for a single test or a pack for multiple tests.

Liquid Test Kits

Liquid test kits are more reliable than test strips.

Instead of dipping a strip in the water, you add a chemical reagent to water in a test tube and match the color change to the color chart.

For some tests, you count the number of drops required for a complete color change.

A liquid test kit will have several reagents for multiple tests.

There are two types of liquid test kits.

Liquid test kits with the color chart: These are basic kits where you have to match color changes to a chart. These kits are cheap but can be difficult to use for people who suffer from bad eyesight or color blindness.

Digital liquid test kits: Instead of matching colors, digital liquid test kits do the reading for you. After you add the reagent to the water in a test tube, you insert it into the digital unit that has a photometer which detects changes in the water. It then provides a precise digital reading on a screen.

Electronic Test Kits

An electronic test kit does not use reagents. Instead, you insert probes into a water sample to get instant readings.

Most electronic test kits provide accurate measurements for pH, TDS, salt, and temperature but tend to be less precise when it comes to measuring chlorine.

Electronic pool testers are the easiest to use. You do not have to add reagents, and you can get multiple readings at once.

Of course, they are more expensive than other types of pool testing kits.

The best choice among these three depends on your needs.

If you want a fast and cheap way to test your pool, get test strips.

If you want a more accurate but affordable testing method, get a liquid test kit.

If you are color blind or have trouble matching colors, get a digital liquid test kit or an electronic test kit. The latter is also the best if you want the most accurate readings (except chlorine a liquid test kit is the best for chlorine testing).

What to Look for When Purchasing the Most Effective Pool Test Kit

You can’t randomly settle on any pool testing kit without knowing the needs of your specific pool. For example, a freshwater pool has different contaminants than a saltwater pool.

Other than the water type, you also have to factor in the type of test kit, test elements, accuracy, and ease of usage before purchasing any pool water test kit.

Let’s discuss why in detail below.

Type of test kit

There are various types of testing kits to choose from. While they all ultimately perform the same tests, the methods are vastly different.

Liquid pool test kits or titrimetric kits are usually the least expensive, but they are the most difficult ones to use. They require you to collect a sample and mix the exact amounts of reagents to obtain accurate results.

While their results are quite accurate, you have to be precise when mixing the reagents. They come as a set of 5-7 bottles, each containing a different reagent to test certain water pollutants.

You can go for water testing strips or colorimetric pool test kits if you want something simpler. They are affordable and simple to use, but reading the results is a pain.

When you dip the strip in the water sample, it changes color, which you then have to compare with the provided color chart to determine the result. Strips can analyze up to seven parameters per strip; however, the results are not as reliable as the results provided by digital pool water testers.

Digital pool water testers are equipped with a metallic probe to check water quality. They can display accurate readings of water temperature, pH level, salt, and chlorine content.

Despite being extremely accurate, a single device can only measure one or two factors at a time. Plus, digital kits are costlier than any other home pool testing kit.

Water Type

The type of water you want to test also determines the best pool water test kit for yourself. For example, a saltwater pool can only be tested with a saltwater testing kit. But since these pools use a salt-chlorine generator for sanitization, a standard water test kit won’t work.

People also resort to using chemicals like pool shock, chlorine, and bromine, along with a pump and filtration system to prevent bacteria and algae from breeding inside the water.

You can test the chemical levels with a standard pH kit or invest in a more comprehensive pool tester for your peace of mind.

Testing Elements

Knowing what elements a pool water kit can detect also helps you choose the right one for your application. For example, where most liquid pool testers can test for various pool chemicals, most digital testers can only report one or two parameters.

The most common pool elements that homeowners want to detect are chlorine, bromine, pH, total alkalinity, calcium hardness, and cyanuric acid.

Fortunately, even the most basic water testing kit can test for pH as well as chlorine and bromine levels. But if you want to test for other parameters, choose a kit with a wide testing range.


The accuracy of a home pool testing kit varies from product to product and from user to user, too, especially when it comes to liquid water testing kits.

When used correctly, liquid testing kits are the most accurate ones; however, the process of comparing results leaves a wide window for human error.

These kits require you to collect a sample of pool water, add specific reagents, and then compare the color results to a provided scale. And unfortunately, not everyone has the same perception of colors.

Pool testing strips are much easier to use but are also subjective to human error because of color-coded results.

Digital pool testers are the most accurate, with a slight error window of 1 or 2 percent. Plus, they are pretty easy to use and read. However, they entail a high upfront cost and can measure only one or two parameters.

Ease of usage

Pool testing kits measure the concentration of different chemicals inside the pool. The testing procedure is so sensitive that even the slightest mistake can result in inaccurate results. Before settling on a certain product, you should carefully analyze how easy to use different kits.

If you choose a digital pool tester, be sure that it can measure the water element you want to test. And if you choose a liquid or strip testing kit, check out the color charts to ensure they are easy to compare results against.

How to Use a Pool Test Kit to Get the Most Accurate Results

Poolmaster Essential Collection Chemistry Case (22260) 5-Way Swimming Pool & Spa Water Test Kit, Small, Neutral

Here are some tips on how to use a pool test kit to get the most accurate results.

  • Read the instructions before you do anything. Focus especially on how to use the reagents. Adding the wrong reagent or using more than the recommended drops will give you the wrong readings.
  • When taking a water sample from the pool, dip your hand up to the elbow. Do not scoop water from the surface, near the skimmer or the return line.
  • If you are using a liquid digital test kit, wash the tube between tests or use a new tube to avoid contaminating the water.
  • Use the white placard included in your liquid test kit to better see the watercolor and match it to the chart. If your kit does not have the card, use anything else you have on hand like a white sheet of paper to create a white background.
  • If you are color blind or are not sure about the color, get a second opinion. If you are color blind, we highly recommend buying a digital liquid test kit or an electronic test kit.
  • Do not use fingers to cover the tubes when mixing water with the reagent. Oils from your skin can affect the readings. Either jiggle the comparator to get a good mix or, if you are using a digital tester, use the included caps to seal the tube then mix.
