Essentials pH Meter

Product Information

The cap is difficult to get off, making it good at keeping the moisture in and preventing the electrode from drying out, but it also means that the fragile glass electrode inside is at greater risk of damage if you are too heavy-handed when removing and replacing the cap. That’s why you need to regularly measure pH; if your medium is too alkaline or too acidic, your plant won’t be able to access all the nutrients they need.

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.Unlike some other pH pens, it uses a single AAA battery for power, which tends to be more popular with users than the button cell batteries that most other pH meters use.

Replaceable electrode meters like our High Accuracy pH Meter are great if you have long-term plans for testing pH.This means that your pH meter is going to be exposed to a lot of water splashes, and at some point, you are almost certainly going to accidentally drop your pH meter into the solution being measured. Check with your pH meter manufacturer, or current educational or professional institution, about acquiring pH buffer solutions. However, even expensive laboratory pH probes have a limited life span as the sliver electrodes and the junctions between chambers within the probe degrades with use, so scientific probes will last for several years but by no means indefinitely.
