Essentials pH Meter

Product Information

If you really must clean the storage solution off of your electrode, rinse it in deionized water and blot it dry on a lint-free towel. It is also susceptible to drying out, if not properly cared for, and is easily damaged by 'oily' fingers, so should never be touched directly.

The unit also displays a low battery symbol to warn you before it degrades the accuracy of important readings. When you take a sample to test, make sure you take enough to submerge the entire electrode and that your sample holder is deep enough to accommodate the electrode. Obviously the more accurate your pH meter reading, the more expensive the pH meter, but also the more you will be able to understand the subtle variations in optimal conditions for your plants' growth. If you’re a brewer or a home cheesemaker, chances are you don’t come to ThermoWorks just for our best-in-class thermometers.That means you’ll need a new electrode or, in the case of a non-replaceable electrode meter, a new meter.

Pen-type hydroponic pH testers are significantly less expensive than the 'always-on' counterparts and so they are often the preferred option amongst amateur gardeners. 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. Another reason to cool your sample is that electrodes degrade faster at higher temperatures, meaning shorter electrode life. Then simply dip the meter into the buffer 7 and hold the calibrate button until it says CAL, the Essentials pH Meter will then re-calibrate the device.

To properly use a pH meter, you have to calibrate it for every measurement session using a known buffer solution.

You are going to be dipping your pH meter into solutions and waving it about a bit to dislodge any air bubbles whenever you take a pH reading.
