pH meters are a great tool to have on hand if you need to test water quality often.

If you have a swimming pool, a hydroponic garden, or even if you just want to make sure your drinking water is at the right pH level. a pH meter makes it easier.

Below I have reviewed the top 4 meters that are available to buy.

Oakton EcoTestr pH 2 Review

This model by Oakton is a strong, rugged beast that is designed to be used often. It is a bigger model and has more functions, hat is represented in the higher price. The bright green case is built to exacting IP67 standards. What that means, is it is completely dustproof in the casing, and waterproof (it floats).

A feature that I like about the EcoTestr is the 3 contact points for testing, most meters only have one. Also the “ATC” or Automatic Temperature Compensation, setting is a nice feature. This setting allows you to maintain accurate readings even with varying temperature changes in the solution you are testing.

The LCD screen displays results immediately after testing. To maintain calibration you need to store 7.0 pH water in the cap and keep it upright. The EcoTestr requires four 1.5V batteries which are not included.

Qimius Digital pH Meter Review

Built by Qimius, this bright blue and red digital pH meter is a great workhorse and can handle a wide range of applications. For its price, it is the best value meter. You also get a lot of included items when you buy this model. It is almost more of a pH testing kit than just a simple meter.

Powered by two small batteries the Qimius is very easy to use, simply insert it into the water and the pH level is shown to you on the large digital display. Readings are calculated and displayed almost instantly.

Calibration is very easy, packets of pre-calibrated testing powder are included with the meter, and instructions on how to use them.

A 30 day money back guarantee is also included.

Jellas Pocket Size PH Meter Review

This model by Jellas is a great budget pH meter and it works great. It is small and compact, there is a reason why it is called pocket size. It is six inches long and only weighs a few ounces. However just because it is small doesn’t mean it can’t do its job well. The black protective cap you can see in the picture protects the small sensing electrode.

Take the cap off and put the sensor into what you want to test. There is a line on the tip that shows the maximum immersion level. When in water, slide the on/off switch to the on position and results are returned to you on the small back-lit screen. Yes it is a bit harder to read, but it is still legible, and a smaller screen decreases the overall size of the meter.

To calibrate the Jellas it comes with two packets of pH buffer powder that allows you to successfully adjust your meter. A small screwdriver is also included to make your calibration adjustments.

Digital pH Meter Review

This pH meter by Box Professional, is a model that has the slightly bigger LCD screen so it makes results reading easier. Batteries are already installed and similar to other models it is very easy to use. Make sure you calibrate the first time you use it by mixing the included buffer powder into distilled water.

The powder turns the water to a known pH level which will then set the calibration for your meter. Now you can swirl the sensing tip into many different types of liquids to find the true pH level.

Results show up very quickly. A protective carrying case is included.
