Are you tired of using pH test strips that give you inaccurate results? Don’t worry, it’s not your fault. The most accurate pH test strips are hard to find.
Like me, you probably thought that they’re all the same. Perhaps you bought a case of alkaline water and became frustrated when you tested a sample and the pH came back acidic? This is a common occurrence, and the problem isn’t you; it’s the pH test strips.
In this article, I show you the most accurate pH test strips for drinking water, saliva, and urine. Once you have a set of accurate strips, you’ll know for sure that your tests are correct.
I also share alternative (better) ways to test pH and a few additional tips you may find useful down the line.

The Most Accurate pH Test Strips
The key to choosing the best pH test strips is to choose a brand that is ionic strength, especially if you’re testing the pH of bottled alkaline water or alkaline water in general.
Click here #ad or the image below to check out the most accurate pH test strips for drinking water with a wide pH range:
Micro Essential Lab recommends these for testing water. They are their Hydrion Lo Ion (LI-5000) test strips.
The wide pH range of 1 to 11 also makes these strips great for general use.
- The roll is 15-feet long
- Includes pH chart
- pH guide
- Carrying case
- Sample tube
- Serrated edge on the roll for tearing off 3″ test strips
- Measures pH between 1 and 11
- Consistent results
- Best strips for testing drinking water
The strips above also come in a narrower pH range. The Micro Essential Lab LI-5900 strips measure between 5 and 9.

How to Test pH Level in Water
The directions for testing water using the strips above are as follows:
- Cut off a 3″ test strip using the serrated edge on the case (be careful to watch your fingers near the edge)
- Place the 3″ strip inside the included sample tube
- Fill the tube with your water, saliva, or urine sample (be careful not to overfill and spill)
- Put the cap on the tube and shake it
- Wait 1 minute
- Hold the tube against the black bar on the included pH test chart
- Match the color of the liquid inside the tube to the included pH color chart
- After you finish, rinse the tube with distilled water (if possible) and allow it to air dry before putting on the cap

For those of you who prefer pre-cut strips, Micro Essential Lab also offers a vial of 100 Hydrion strips. However, these strips aren’t as accurate as LI-5000 and LI-5900 test strips above.

Here’s one final option for testing saliva and urine #ad:
Now you know all the most accurate pH test strips for testing all liquids at home.
Are there better options for testing pH than strips? Yes.
Better Alternatives for Testing pH at Home
Did you know you can test your pH all the way down to the hundredth? The problem with the strips above is they only provide a certain level of accuracy.
Even the most accurate pH test strips can’t provide the same level of accuracy as a decent digital pH meter.
However, it’s important to choose the right pH meter, or you’ll run into the same problem you did with the strips. Cheap pH meters are notorious for breaking.
A cheap pH meter may work wonderfully for a month or so before suddenly dying on you, and nobody wants that.
It’s best to buy a mid-range digital pH meter (or better) to ensure years of accurate results. Plus, it’s fun to see a pH reading in the hundredths if you’re a science nerd like me.

What’s cool about this meter is it also reads the temperature of your liquid.
To learn how to use and calibrate a digital pH meter, my article How to Test Your pH Level Without Strips is helpful.
- Measures pH between 0 and 14
- Measures both temperature and pH
- Carrying case included
- Calibration solutions included ensuring highly accurate readings
- Instant readings down to .01
- 24-hour lifetime customer support
- This meter is great for testing alkaline water brands to ensure they’re delivering on their pH promises
- After you finish using it, it’s best to rinse the tip with distilled water and allow it to air dry before replacing the cap
- Follow the instructions to calibrate it before the first use
- Store it in a cool, dark, dry place when not in use
- If you use it to test the pH of your urine, it’s even more important to rinse it after you’re done using it

pH Tester Drops
Another alternative to pH test strips is pH tester drops. These are less messy, easier to use, cheap, and provide accurate results.
To use these drops, put your sample in a glass or sample tube and add a couple of the tester drops. Then, allow the drops to mix with your sample. Finally, match the color of your sample to a pH color chart.
Click here #ad or the image below for a reliable brand of reagent pH test drops:
These are the best pH tester drops for testing alkaline water. You can also use these to test urine, but darker colored urine can make the results hard to read.
The kit comes with everything you need: tester vial, two 20mL bottles of reagent tester drops, pH chart, and a dropper bottle.
They have a pH testing range of 4 to 10.
- The strips are good for getting an idea of pH, but even the most accurate pH test strips are less accurate than the digital pH meters I showed you above.
- You’ll also find that the tester drops are better than the strips because they’re easier to use and usually more accurate.
- Always remember to read the instructions to ensure you’re doing it right. Once you run your tests correctly a few times, testing liquid pH becomes second nature.
- Remember to calibrate your digital pH meter to get the most accurate results.
- Alkaline water brands recommend a pH meter over the strips. I’ve seen many reports written by people who claim alkaline water has an acidic pH. Since the companies closely monitor the pH of their water, the people who claim the water’s acidic almost always use the wrong pH test strips or don’t know how to test pH correctly.
Now you know which strips are the most accurate pH test strips.
Remember to check the pH range of the strips before you buy because the strips with the smaller pH ranges aren’t made for testing alkaline water with a high pH.
