Essentials pH Meter

Product Information

Replaceable electrode meters like our High Accuracy pH Meter are great if you have long-term plans for testing pH. Been brewing for a while and you’re planning on keeping at it? You should get a replaceable electrode meter. But if you’re working on a one-time project or aren’t planning on using your meter for longer than a year, just go with a low-cost non-replaceable meter like our Waterproof pH meter. As already noted, calibrating every time you use your meter is the best practice. But you also have to calibrate correctly. If you’re measuring something that is basic, always calibrate first using the 7.00 pH reference buffer and the 10.00 pH buffer to establish a proper reading. If you’re measuring something on the acidic side, calibrate using the 7.00 pH reference buffer first and then use the 4.00 pH buffer. purified (distilled or deionised) water (to make up fresh KCl storage solutions and to rinse between measurements) Clean your electrode after use. Rinse your electrode with distilled water and blot or dab dry with a lint-free tissue. You may store your pH meter once clean and dry.

Overall, the PH-200 from HM Digital is an excellent all-round pH meter that is probably one of the best consumer pen-type pH meters that you can currently get for hydroponics. Before we go into the common mistakes and their remedies, it’s important to understand the differences between replaceable electrode meters and non-replaceable electrode meters. The names of the two groups are self-explanatory, but whether you buy a replaceable electrode meter or not depends on how you intend to use it. The PH-200 by HM Digital is one of the more expensive options out there for pen-type pH meters, but for the serious hydroponic gardener, it is well worth the extra cost knowing that you have something that is extra accurate and reliable. The PH-200 is waterproof, tested up to a rating of IP-67 (ie. it can be submerged in water up to 1m). It also comes with a clear cap so that the all-important electrodes can be monitored for wetness during storage. Like most pH meters, it has all the standard utilities like auto-off to conserve battery levels, a data-hold function that allows you to hold a pH reading if you can't immediately see the display (very useful for less accessible nutrient solutions), and a low-battery alert. Because of the ionic nature of the electrode glass itself, when it is stored in ion-free water, the Law of Diffusion describes how the ions will leave the glass to try to establish an ionic solution in the water itself, creating more equilibrium. That exodus of those ions from the glass to the liquid depletes the glass of its pH-measuring qualities, rendering the electrode useless.To properly store your pH meter, it is imperative that you use pH-electrode storage solution. The storage solution is hydrating and is properly balanced with the right kind of ions. If you suddenly run out of storage solution during a testing process, deionized water can be used in the very short term until more storage solution can be obtained. Not calibrating properlyThis mistake is common and easy to fix. The pH meter reads the total electrical potential difference on the surface of the electrode, so, if half of your electrode is outside the sample solution, it’s missing half of the reading. That kind of difference is not acceptable! As noted above, electrodes don’t last forever. If you’ve had your meter for over a year and you find that your readings aren’t quite what you think they should be, you might have a bad electrode. That means you’ll need a new electrode or, in the case of a non-replaceable electrode meter, a new meter. Bluelab’s wall-mounted monitors offer comprehensive and user-friendly features, allowing you to have complete peace of mind. In addition, our Connect range of monitors will allow you to access your pH data remotely. Always on, always monitoring, always available. If you’re a brewer or a home cheesemaker, chances are you don’t come to ThermoWorks just for our best-in-class thermometers. You probably also love our great selection of pH meters!

Right about here, we really start to see how much more trouble pH meters are than thermometers: the storage and buffering solutions are essential to proper use of your pH meter, which means that any time you measure pH, it’s going to start looking like you’re playing with a chemistry set. For me, that’s a fun thing, but it certainly isn’t as convenient as a Thermapen ®. Not submerging the electrode While many pH meters require you to manually test your pH and adjust these levels yourself, pH automation will do this automatically on your behalf. Our pH controllers will not only monitor your reservoir but also adjust pH levels when measurements fall outside of your optimal pH target range. To improve the ongoing accuracy of your pH meter, we’d recommend that you clean and calibrate your pH probe regularly. We offer pH buffer solutions, as well as pH probe storage solutions, allowing you to maintain your pH probe easily.It is easy-to-use as you can just dip the sensor into the test solution - stir and wait. This unit will deliver a stable reading in about 20 seconds. The meter has a minimum lifespan of about 1 to 3 years depending on the rate of sampling. The energy-saving feature shuts off the tester when it is not in use. Calibrating Bluelab’s pH meters couldn’t be easier. The easy-to-follow calibration process will ensure that your pH measurements remain accurate; if you’re using your pH meter every day, it will need to be calibrated more regularly. Either way, you need to be aware that the electrodes in your pH meter are going to wear out. pH meter electrodes are like old-fashioned candescent light bulbs: over time they just ‘burn out,’ no matter how carefully you use them. With non-replaceable electrode meters, it means you’ll need to buy a new meter in about a year’s time. But with replaceable electrode meters, it means you’re going to have to buy replacement electrodes to keep your pH meter working long term. pH Meter Electrode Lifespan Why don’t we make an electrode that doesn’t burn out and need replacing? The answer is that this technology simply doesn’t exist yet. As it stands, there are physical constraints on the system that prohibit the creation of longer-life or permanent electrodes. Current pH electrodes have a lifespan of about one year or up to 18 months at the most (with less frequent use). If you properly care for your electrodes, you’ll still need to replace them roughly annually. That said, there are things you can do to avoid damaging your pH electrodes. They can be fairly fragile and require a little extra TLC, which we’ll discuss below. Common pH Meter Mistakes and How to Avoid Them A replacement probe with 2 meters of cable for Bluelab Combo and pH Meters as well as the Bluelab Guardian Monitor.

Please note: Some of our new replacement electrodes come with just one larger cap that holds the storage solution in a little sponge against the electrode. If you have one of these newer replacement electrodes, just be sure to saturate the sponge with storage solution, loosen the threads on the cap to allow the air to escape as you press the electrode into the sponge, and then retighten the cap for storage. When you remove the electrode cap from your meter, there will be a tiny amount of storage solution that clings to the electrode. Do not wipe it off. Why not? Because what the pH meter is actually measuring are tiny, tiny changes in electrical potential. If you wipe the surface of the bulb, you can induce a tiny static electrical charge on the surface of the glass. Though minuscule, this static charge can be large enough to throw your readings off. For crops that need monitoring 24/7, our wall-mounted monitors and pH controllers will measure your key parameters, including pH, and alert you when these measurements move out of their optimal range.
