Summary
- With pH test strips, you can measure your pH level from home. The pH values from 0-6.9 are acidic, at 7 it is neutral and from 7.1-14 it is basic.
- pH test strips are available in litmus paper, plastic and paper pads. You can use these pH test strips to test your urine and saliva or other liquids.
- Which pH test strip is right for you depends on what you want to measure and how accurate and reliable your test result should be.

Guide: Questions you should ask yourself before buying pH test strips
What are pH test strips?
| pH value | Type |
|---|---|
| 0 - 6.9 | Acidic |
| 7 | Neutral |
| 7.1 - 14 | Basic (Alkaline) |

When should you use pH test strips?
If your body is over-acidic, the consequences are fatigue, bad skin, bad teeth, headaches and obesity. Especially when bladder infections are suspected, people like to use the pH test strip to find out whether a bladder infection is present. Furthermore, pregnant women can use pH test strips to monitor their values and react quickly in case of problems. You can also use pH test strips to detect vaginal and urinary bacterial infections. If you quickly detect a deviation in your vaginal alkaline acidity, you can react quickly and restore the balance.

What is the ideal pH value?
For optimal balance, your pH should be between 6.8 and 7.4.
The pH value is subject to fluctuations. It always depends on when you measure it and what you have eaten. For example, the pH value is lower in the morning than in the evening. Furthermore, vegetarian meals tend to be alkaline and meals with meat tend to be acidic.
For whom are pH test strips suitable?
No matter if you are a man or a woman, young or old! Anyone who wants to monitor their acid-base balance to avoid over-acidification can use pH test strips. You can even check the acid-base balance of your dog or cat. In short, anyone can use pH test strips.
How to use pH test strips?
pH test strips: Step 1: Wash your hands and take a strip with dry fingers.
Step 2: Hold the test strip in the urine or other liquid for 1 second and then shake off the strip.
Step 3: The test strip changes colour. Hold the strip up to the colour chart and match the colour to the chart to find the pH value.
pH test roll:
Step 1: You can determine the length of the test strip at your own discretion and tear it off.
Step 2: Hold the pH test strip in the urine or other liquid for 1 second.
Step 3: You can now compare the test strip directly with the colour chart on the plastic housing and determine your pH value.
How do you interpret the result of pH test strips?
In principle, the colour table is arranged in such a way that it is listed from red to dark blue.
Red means very acidic, orange to yellow is also acidic, light green to dark green means neutral and light blue to dark blue is basic.
| Solution | Classification | pH | Type |
|---|---|---|---|
| Stomach juice, fruit juices, cola, vinegar | Ultra acidic | 0-3.5 | Dark red |
| Wine, beer | Extreme acidic | 3.5-4.4 | Red |
| Coffee | Very strongly acidic | 4.5-5.0 | Dark orange |
| Tea, skin surface | Strongly acidic | 5.1-5.5 | Orange |
| Rain, mineral water | Moderately acidic | 5.6-6.0 | Dark yellow |
| Milk | Slightly acidic | 6.1-6.5 | Yellow |
| Saliva, Pure water | Neutral | 6.6-7.3 | Light yellow-light green |
| Blood, sea water | Slightly alkaline | 7.4-7.8 | Green |
| Pancreatic juice | Moderately basic | 7.9-8.4 | Dark green |
| Soap | Strongly basic | 8.5-9.0 | Light blue |
| Bleach, concrete, caustic soda | Very strongly basic | 9-14 | Dark blue |
What types of pH test strips are there?
Furthermore, a distinction is made between whether you want to measure the value with saliva or urine or with other liquids. Other liquids include the water in a pool or aquarium, the composition of the soil or, for example, drinking water.
What alternatives are there?

Another alternative would be drops or pH sticks. The application of the drops works the same as with the test tubes and that of the sticks the same as with the pH test strips. The alternatives are summarised once again:
- pH test meter
- pH test test tubes
- pH test drops
- pH test sticks
How much do pH test strips cost?
Decision: What types of pH test strips are there and which is right for me?
Below we have listed 3 types of pH test strips with their advantages and disadvantages to help you decide. In summary, these are:
- litmus paper pH test strips
- pH test rolls
- pH test strips made of paper pads
What are the advantages and disadvantages of litmus paper pH test strips?
Litmus is a type of lichen that changes colour when it is mixed with acidic or basic substances. For example, the litmus paper strip turns red when the value is less than 4.5 and blue when the value is greater than 8.3. Between 4.5 and 8.3, the litmus paper pH test strip turns purple.
Since litmus only divides the acid-base balance into 3 parts, the litmus pH test strip is only for rough estimates and should not be used for exact measurements. The accuracy and quality of the pH test strips also depend very much on the manufacturers and suppliers.
What are the advantages and disadvantages of pH test tapes?
pH test rolls are like pH test strips. You can decide for yourself how long you want your test strip to be and simply tear it off the roll. You can use the pH test roll to measure your acid-base balance, liquids, food, pools, aquariums and drinking water.
What are the advantages and disadvantages of pH test strips made of paper pads?
These pH test strips are particularly suitable for pools, aquariums, soils, lakes, drinking water, but also for food. Simply measure from the comfort of your own home and after about 30 seconds you will have the result.
Buying criteria: You can use these factors to compare and evaluate pH test strips:
In the following, we have listed a few more factors to make your purchase decision a little easier and to show you factors that you can compare. In summary, these are:
Measuring range
There are pH test strips that have a measuring range from 0 to 14 and thus cover all ranges. This type of pH value measurement is usually very coarse and only measures in whole steps.
Furthermore, there are types of pH test strips that concentrate on the middle part, but indicate it more precisely. This allows you to measure to one or two decimal places.
Reliability/Accuracy
To get reliable and accurate pH values, you should measure your values at least 3 times a day. The pH values tend to be more acidic in the morning and more alkaline in the evening. Litmus only divides the acid-base scale into 3 parts and thus only serves as a rough classification.
If you want to measure pH values precisely, pH test meters or pH test strips made of paper pads are suitable.
Quantity
Quantity could also play a role in your purchase. If you only want to measure your pH values for a short time, you can buy a small quantity of pH test strips. A small quantity is also cheaper.
However, if you want to monitor your acid-base balance over a longer period of time, we advise you to buy a larger quantity to get more accurate comparisons with the same product. In general, you can buy pH test strips from 50 to 500 pieces. pH test rolls are on average 5 metres long.
Brand
There are very many suppliers of pH test strips. If more values are tested, the price also increases.
Some products test other values besides pH, such as glucose, protein, nitrite and leukocytes.
The most popular manufacturers and suppliers are listed below:
- Merck
- Aquanatura
- Macherey-Nagel
- Roche Diagnostics
- Gabmed
Facts worth knowing about pH test strips
Acidic vs. alkaline foods
Acidic foods: fish, meat, sausage products, vinegar, cheese, yoghurt, ready-made products, industrial sugar, coffee, alcohol, flour, bread, pasta Alkaline foods: parsley, nettle, kale, spinach, fruit, mushrooms, nuts, cucumber, fennel
Tips to keep the acid-base balance in equilibrium
Tip 1: In the morning, drink a glass of warm water with a dash of lemon. Tip 2: Alkaline baths are good for the acid-base balance, for the skin and for the muscles. Tip 3: Sports and sauna visits also help you to find your balance. Tip 4: Massages in any form bring your acid-base balance into balance.
The 3 most common mistakes when measuring
- Acids and bases: Indicators usually have a slightly acidic or basic pH value. Although this is usually too low to influence, it can cause a bias of one pH point in liquid indicators.
- Salts: If 2 solutions are tested with artificial material and the same value, this will influence the result. Since the salts of the materials are different, this will affect the result colour. The pH values are only accurate with a salt value below 0.2 N.
- Temperature: The temperature should be constant during the measurements, because different temperatures change the concentration of hydrogen ions and distort the result.
