Ph calibration solutions are essential in making sure that your ph measurements are accurate. You may be wondering why you need them and how they can help you keep your samples at the right ph. In this article, we’ll cover everything you need to know about ph calibration solutions, from their purpose to what to look for when choosing one.
What are ph calibration solutions?
Using a ph calibration solution is a common procedure in many industries, including chemistry and microbiology. These solutions often come packaged with an indicator that can be dropped into it to determine the ph levels of a substance by determining when colour changes are present. There are two main types of solutions commonly used for ph calibration: one with hydrochloric acid and one with sulfuric acid. While there is some overlap in what each can be used for, as well as their pros and cons, they also have unique properties. In order to know which type you need for your process, or even if you need one at all, here’s everything you need to know about using them in different applications.
Why do you need ph calibration solutions?
In order to maintain a safe and healthy indoor environment, a solid understanding of your pool’s ph level is crucial. A well-balanced pool not only helps avoid potential health risks for swimmers but also allows you to reach desired efficiency levels for running a swimming pool or spa. The proper balance between chlorine and pH can have a major impact on how efficiently your pool or spa functions. While we don’t recommend trying to mix up your own ph calibration solution at home, there are other ways that you can achieve high levels of ph calibration in your pool or spa. Home test kits can be used for measuring algal growth in pools and spas as well as maintaining normal levels of carbon dioxide within your water source.
How often should you calibrate?
It all depends on how often you’re using your meter. If you use it once a day, then you might be able to go up to four weeks before a calibration. If, however, you’re measuring blood sugar levels in a handful of different patients every single day, your meter will likely need calibrating more frequently than that. The best way to tell if it’s time for a recalibration is simply by checking its accuracy. When you test with your new control solution, compare it against a known accurate control (either another calibrated meter or known standard solutions). By doing so, you’ll know if your meter still has accuracy in tact and is capable of producing an accurate result—in which case, there’s no need for recalibrating just yet.
What is the difference between liquids and tabs?
Many ph calibration solutions come in both liquid and tablet forms. There is not a huge difference between them, so it really just comes down to your preference. Tabs are great for keeping your solutions fresh because they usually don’t need refrigeration. They are also less messy than liquids, making them good for use at home or on the go with little mess left behind. Of course, when it comes to accuracy, tabs do not offer quite as much flexibility as liquids—some only reach up to 8.0 ph!
