Are you searching for an indicator that shows whether a liquid is acidic or basic? Would a benchtop pH meter be right for you? We have a guide on how this tool can help you measure liquids. If you hear about pH meter, you may think, big expensive machine, but in fact, there are many budget-friendly options. We will be going through some best pH meters available for several budgets, what you should look for to choose the right one without breaking the bank in this guide.
For those that are new to pH measuring and don’t want to spend a fortune, there are several easy, yet good options to choose from. For example, the Labtech brand makes a simple benchtop pH meter that is extremely simple to operate and costs roughly $50. This pH meter that comes with pH electrode and temperature probe, which helps to measure both the pH and temperature of the liquid, adding good points to it. It is capable of measuring pH levels between 0 and 14, so it is ideal to test most liquids. This is a great choice for home use or for school projects if you want to learn about pH levels.
The Labtech digital benchtop pH meter is another good option for beginners. It's not much more expensive — about $100 — but has more to offer. It features a large digital display which makes reading the measurements a genuine breeze. It also has an integrated computer to assist in auto calibration. It also means that you won’t have to keep resetting it every time you use it! It can also take temperature readings, which are important for reading pH accurately. Ideal for smaller labs or for anyone needing to check pH frequently.
Another important aspect is the pH meter's accuracy. Accuracy refers to how close the readings are to the actual pH of the substance you are measuring. Precision, in contrast, is how repeatable the readings are when you test the same liquid repeatedly. Especially if you plan to use your pH meter often, you want to choose one that is both accurate and precise. This serves to make sure you get consistent readings every time you test.
We know of several good pH meters with high recommendations if you can afford to spend a little more. As an example the Orion Star A211 is a very exact pH metre excellent for laboratories. It has a big color touchscreen that is easy to Navigate and read the measurements. There is a capacity of storing 5000 readings in this meter, I mean that's quite a data! At about $800, the Orion Star A211 Is a quality lab work investment.
It is also worth looking into the YSI MultiLab 4010-3 pH meter. That's incredibly versatile as it can measure more than just pH, also looking at conductivity, dissolved oxygen, and a whole slew of other factors. It also has a large color touchscreen and can store up to 500 readings. The YSI MultiLab 4010-3 pH meter is priced approximately $2300, which the genius in multi-tasking makes it an excellent choice for bigger lab, or people needing multi-user results.
The Hanna Instruments HI5221 pH meter is another excellent mid-range selection. The meter has an oversized LCD display and is capable of registering up to 100 readings, making it great for tracking results. It also has a multitude of advanced features, including automatic temperature compensation to help ensure that you get the correct results even when testing liquids that are not the same temperature as what you are testing. The pH meter used was the Hanna Instruments HI5221, which costs around $800.
