pH METER [Electrode Buffer storage solutions/tablets]: pH 1 to 14
Price range: $ 26.80 through $ 124.00 excl. GST
• A variety of buffer solutions and buffer tablets for use with electrodes and pH Meters.
• NEVER store a pH electrode in distilled water as the distilled water absorbs the ions out of the electrode electrolyte.
• By cleaning well after use and storing electrode in storage solution or a buffer solution of about pH4 it is possible to extend the electrodes life considerably.
• As pH electrodes age they get sluggish in their operation and take longer to settle on a reading.
• Given this more time is needed when calibrating and taking readings.
• If obtaining a reading takes too long this is an indication that the electrode need as replacing.
INFO: TAKING CARE OF pH METER ELECTRODES (PLEASE READ CAREFULLY.)
– Many schools send pH meters to us for repair. We find that for about 95% of these, the pH electrode is at fault.
– Given care it will last for quite a while – up to 3 years – but even for the best electrode available it is considered acceptable if it functions for 1 year once activated.
– If not cleaned properly or left to dry out it may not be able to be resurrected.
– Try soaking in pH storage solution (refer to pH Storage Solution, cat. ALP 1825) for 24 hours.
* Buffer solution sachets and tablets are a great option if you do not use your pH meter regularly.
* Liquid buffer solutions start to deteriorate once the bottle is opened whereas, with tablets and sachets, you can make up a fresh batch as required.

(Wikipedia excerpt: ..."A pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH.[2] The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, and so the pH meter is sometimes referred to as a "potentiometric pH meter". The difference in electrical potential relates to the acidity or pH of the solution.[3] Testing of pH via pH meters (pH-metry) is used in many applications ranging from laboratory experimentation to quality control.[4]...")
