Information about Apera Insturments PH20 Value PH Pocket Tester:

It is easy to think about how much technology has evolved in the last century that at times, we might feel overwhelmed with the choices. Undecided, some of us would dismiss technology and play the ancient times card. For instance, who even thinks about pH in the old days and plants did proliferate.

But that is the beauty of science and technology. Not only do we understand better, but in the process, we use this understanding to make growing plants even better.

Take hydroponics, for instance. Babylonians used hydroponics in the Hanging Gardens. Too bad it no longer exists today, but it is one of the wonders of the ancient world. So, think about your indoor hydroponics set up and the tools such as pH meters available to you. What you have is something the ancients could only drool for.

So, you want to know which pH meter you could use for your plant?

We know how difficult it is to find the right product at the right price on Amazon. As a matter of fact, we had a difficult time too when we were looking for products to feature here. But we still did it so that you could lessen the time you use for searching and instead, focus on choosing.

On Amazon, being the world’s largest online B2C marketplace and having tens of thousands of vendors, looking at the sheer volume of results whenever searching for products is overwhelming. Adding to the confusion are similar looking products with different brand names. That is because those are likely small vendors who purchased them in China and have their own brand stamped on the product and printed in the packaging.

How is Apera Instruments different from the others, then?

Apera Instruments


Apera Instruments is in the business of providing scientific instruments for water analysis for more than two decades. It has an ISO 9001:2008 certified manufacturing base located in Shanghai, China. In the United States, they have a branch in Columbus, Ohio.

Among the many instruments they designed, engineered, and produced, one that caught our attention was the PH20 Value pH Pocket Tester.

Key Features

The PH20 is not the Apera Instrument’s top-of-the-line series. Instead, this is a model that is ideal for use in the home. Although it does not offer the same range of precision, it is still one of the best you could find to test pH levels.

Besides using it to test your nutrient solution, it could also be used in a wide variety of applications such as in water supplies, agriculture, aquaculture, and others.

Everything You Need For Reliable PH Test

The most important thing about pH meters is its ability to take an accurate measurement with the least tolerance.

PH20 measures both pH level (0 to 14.0 pH) and temperature (0 to 50 °C) with an impressive resolution of 0.1 pH and 0.1°C. It also has an outstanding accuracy of ±0.1 pH and ±

One of the most irritating in using a testing instrument is the difficulty in reading the results. PH20 does not have that nuisance with its impressive ultra-clear LCD screen with a wide viewing angle of 180 degrees that display both pH and temperature readings, as well as other indicators.

Besides the accuracy of the instrument, another problem encountered by those who purchased obscure and cheap products is the housing material. PH20 uses an IP67 waterproof and dustproof material, so that is no longer a concern. And one more thing, if in case this pH tester falls accidentally in water, it floats.

Apera Instruments PH20 Value pH Pocket Tester comes with everything you need out of the box. Instead of spending more time and money looking for calibration solutions, it is already included in the package, as well as AAA batteries, a lanyard, and a carrying case.

Where To Use
Where To Use

The PH20 has an efficient power usage with a continuous usage of up to 2,000 hours before the batteries need to be changed. Apera Instruments also has a two-year warranty on the PH20, but for the probe, it is only six months.

All these are great, but what do customers think?

Overall, the feedbacks have been highly positive. In fact, after checking and reviewing all pH meters we could find, the PH20 scored the highest net customer satisfaction rating.

Although there was one negative criticism, it was also because the customer did not realize that the PH20 cannot take accurate measurements of distilled water. To be fair to the company, it is clearly stated in the descriptions and in its operation manual.

A few other issues were reported but were mostly due to failure in following the instructions provided for the proper calibration and use.

If you have a need to use a pH meter, then the question is if this is the right product for you. Equally important is if this unit works as intended. Finally, are there better or more practical choices?

In terms of performance, the PH20 is right up there on top. As for the cost, well, that is one of its best features too. Being the highest rated pH meter on Amazon, it does not come with the high price tags of some other units, but it is not the cheapest too.

Although there are cheap alternatives in the range of $20 to $26, the PH20, which cost under $60 is not that expensive, especially when you consider its quality, accuracy, and durability.

Like any product, there is a small chance that there might be a defective unit. Even so, it is easy to contact Apera Instruments and they are quick in resolving any issues. In fact, one of the things customers like is how responsive their support team are in addressing any concerns.

At the end of the day, we do highly recommend this product for one simple reason. It works as intended and nearly everyone who purchased the PH20 is more than satisfied. Buy Apera PH20 Meter here!
