15 Best pH Testers Reviews 2019 | For Accurate Reading

Best pH Testers

In today’s dynamic world, you may find many measuring gadgets that test the pH level. However, there are only few that live up to the standard.

People have started to find pH meters very useful than a strip tester. The meter gives an accurate reading and doesn’t leave any room for doubt.

The features of the meter vary with the brand. Each brand has its unique feature. Let’s have a look at the reviews of 15 best pH testers that we have compiled for you.

Buying Guide:

Before purchasing the pH meter, you should consider these 5 essential factors. These include:

Calibration:

Calibration is when you achieve the results with pH buffer solutions.

The usual type of buffers available in the market are 4, 7 and 10 that are coded red, blue and yellow.

While purchasing, consider the meter that uses 2-point calibration. This will measure the accurate results for acidified food.

If you buy 3-point or 5-point it would increase the range of pH.

Accuracy:

The accuracy of the pH meter depends on the range. Meters commonly range from ±0.1 pH to ±0.001 pH. Among which ±0.01 is an ideal choice for quality research.

However, a pH meter with ±0.10 is considered to be affordable for students.

Electrode:

This measures the concentration of hydrogen ions. When it comes to pH meter, purchase the ones which have a low-cost replacement of electrode bulbs. Or, it can cost you.

Temperature:

This is the most significant factor that can affect the pH meter.

For an accurate result, the calibration should match the same temperature. Some advanced pH meters would have automatic temperature compensation.

Portability:

Where will you use your pH meter?

The best advice for you is to consider the pH meter that is compact in size for convenience. Also, meters that can float in water can be considered as they are durable and waterproof.

You can also consider benchtop meter if you want to use in a laboratory.

Frequently Asked Questions

What does a pH tester do?

A PH tester measures the hydrogen ion activity also known as acidity or alkalinity.

It measures the acidity using its electrodes. It measures the voltage (electrical potential) produced by the solution.

The electrodes are inserted in water or any other given solution, and then it measures the acidity. It shows the results of PH on the display screen of the device.

Do pH strips expire?

Yes, PH strips do expire. The expiry date of PH strips is given on the bottom of the bottle.

However, if they are stored in a safe place properly, then it can last for approximately 3 or 4 months

How can I test my pH meter?

Take off the electrode cap from PH meter. Turn on the PH meter it will automatically calibrate itself.

When the calibration is complete. Insert the PH meter in a given solution to check its acidity or PH levels.

The PH meter depending on its measurement speed will measure the PH. After measuring it will display the results on the device screen

How do pH levels work?

The PH meter reads the levels of acid and base. The scale starts from 0 and goes up to 14. The neutral PH level is 7.

The PH level which is less than 7 is acidic, and the PH level which is greater than 7 is basic.

How accurate is pH paper?

If you want accuracy from one PH to two than PH paper is great.

It is great for good qualitative work. The PH paper shines from one side if the PH levels differ from one another.

How long do pH test strips last?

If the PH strips are stored in a safe place properly, then it can last for approximately 3 or 4 months.

The expiry date of PH strips are given on the bottom of the bottle.

What is Hydrion pH paper?

Hydrion PH paper is a series of different colors. When the PH level changes the color changes accordingly on the Hydrion paper.

What do the colors on the pH strips mean?

Each color defines a different PH level on the strips when its inserted into the solution.

Why is it important to calibrate the pH meter?

Modern PH meters automatically calibrates itself when turned on while some PH meters don’t.

Therefore, it is necessary to calibrate the PH meter to get fast and accurate results while measuring the PH.

Why does the pH scale range from 0 14?

The pH scale ranges from -infinity to +infinity.

There is no reason, in principle, that you cannot have negative pH values or values > 14. The neutral PH level is 7.

The PH level which is less than 7 is acidic, and the PH level which is greater than 7 is basic.

The concentration of H+ and OH- ion is the same when the PH level is neutral.

Are pH strips accurate?

There are a variety of PH strips available in the market. It is an easy method to measure PH levels.

The PH strips are accurate and very cheap. But it is said that the PH meters are more accurate while measuring the results of PH.

It can display the accurate number of PH in the solution. In PH strips it is hard to recognize colors unless you are a professional.

How do you read a pH strip?

The neutral PH level is 7. The PH level which is less than 7 is acidic, and the PH level which is greater than 7 is basic.

The concentration of H+ and OH- ion is the same when the PH level is neutral. The PH strips show a variety of color. Each color defines a different PH level on the strips when its inserted into the solution.

A color card is given to check the color of PH strip to measure the color and find the result by matching the color with the color card.

However, It is hard for most users to distinguish the difference between colors.

Conclusion

Once you know how to read the figures accurately, it becomes a useful gadget in your life.

The process of calibrating seems difficult, but once you understand it carefully, it’s very simple.

It can be used in various applications such as aquariums, pools and more.
