pH METERS: Variety

A variety of pH Meters and electrodes for measurement use including: Conductivity, Hand-held, Integral, Multi-parameter, Electrodes, Gel-filled, mV, Temperature, 6-Pin or 8-Pin. 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 ...
