Buying Guide and Advice

Detailed reviews of the best pH meters

When reading the reviews remember that distilled water has a pH of 7, and that the pH scale goes from 0 to 14. In addition take note that pH meters are different from ORP meters, TDS meters and dissolved oxygen sensors, although they are often used in combination to rate the quality of different type of liquids.

The Beginners Choice

The Embryant Digital High Accuracy Pocket Size Handheld pH Meter is an easy and affordable way to accurately test the acidity or alkalinity of solutions. Simply immerse the electrode in a solution thats either alkaline or acidic and read the pH value right of the device. This product is ideal for everyday testing and hobby use, but even though the accuracy is said to be between 0.01 and 0.05 pH, don’t expect extreme ph scale accuracy without at least calibrating the device with a buffer solution.

This Embryant pH Meter is perfect for simply testing the pH of the water in swimming pools, aquariums or in the tap. It can also be used in a basic laboratory setting, but since it is not very durable and the accuracy can be questioned, we recommend one of the other more professional pH meters featured in this article for laboratory use.

Specifications

  • Measuring Range: 0-14 pH
  • Advertised Accuracy: 0.01 pH
  • Automatic Temperature Compensation (ATC)

This pH meter by Embryant is one of the best selling products in the Lab pH Meters category on Amazon.com, and with an average user rating of 4.2 from over 425 reviewers, you can be certain that this is an excellent choice if you are looking for a low end, affordable and all around pH meter as an acid/alkalinity indicator.

The Hobbyist’s Favorite

If you think of yourself as more than a beginner, but still not ready to get full on professional gear, the Dr. Meter PH838 0.01 Resolution High Accuracy Pocket Size pH Meter with ATC is just for you. This pH meter is highly reliable and has an impressive accuracy of 0.01. The pH meter is handheld and very light. It also comes with a carrying case for ultimate portability and convenience.

This pH meter is widely used, and is very popular in education and for water treatment, because of the highly accurate, reliable and quick readings. It is a better alternative to ph test strips og litmus paper.

The Choice for the Small Laboratory

Last update was on: November 23, 2021 1:42 am

Our third featured product is the HMD PH-200 Digital Professional Waterproof 0-14 PH & Temperature Meter which is the perfect choice for the hobbyist who wants a more professional pH meter, as well as the small laboratory who want’s a semi-professional device with high accuracy, extreme durability and auto ranging three point calibration with digital fine tuning.

One of the extra features that this pH meter has over the other featured products is that it is waterproof, and includes a storage solution that makes sure that the pH meter is always calibrated and measures accurately.

Specifications

  • Measuring Range: 0-14 pH
  • Advertised Accuracy: 0.01 pH
  • Automatic Temperature Compensation (32-176°F)

The Professional pH Meter

Last update was on: November 23, 2021 1:42 am

This pH meter by Horiba is meant for a professional environment where durability, accuracy and ease of use is crucial. The Horiba LAQUATwin pH33 pH Meter has an accuracy of 0.01 pH and features flat sensor technology which allows for a convenient, extremely easy testing process. This product requires only a few drops of the solution put onto the ph electrode to be able to accurately read the pH value. Instead of immersing the pH meter in the solution, users can also place a small sample directly onto the ion selective membrane and get the results instantly displayed on the LCD screen.

Horiba LAQUATwin pH33 pH Meter also features an easy calibrating process. With the touch of a single ‘cal’ button the user can easily calibrate the device with the help of the calibrating solutions that accommodate the product.

Specifications

  • Measuring Range: 0-14 pH
  • Advertised Accuracy: 0.01 pH
  • Automatic Temperature Compensation

As a bonus, Horiba is offering a 1 year warranty on the pH Meter (B-213). All these extra features, combined with the high accuracy as well as the ease of use is also reflected by the price tag which is relatively high – doesn’t change the fact that this is definitely close to the best pH meter available.

One of the best pH Meters for Water

When it comes to the best pH meters specifically for water testing, theres one meter that simply blows all other ph meters out of the water (no pun intended). I’m of course talking about the WTW ProfiLine pH 3310 pH meter. It’s one of the most durable and rugged pH meters in the industry and it’s specifically made for testing the pH of water.

It’s waterproof all the way down to about 300 ft. and it’s auto-calibration feature makes sure that your readings always are accurate. On top of that this meter has a range of -2 to 20, which means that no matter the solution your testing you’ll be able to record the pH onto the 200 step datalogger.

This product is truly one of the very best pH meters on the market, especially for testing the pH of water. Get one of these and your set on that front for life.
