Electrodes & probes

Electrodes & probes are the sensing elements that plug into pH, dissolved oxygen and conductivity meters. Water quality analysts, food laboratories and teaching labs buy from this Instruments & Spare Parts sub-category to replace a worn electrode or extend an existing meter.

All 88 listings are Apera Instruments electrodes and electrode accessories. pH options include the PH60-E pH electrode and the PH60S-E pointed pH electrode for pushing into semi-solid samples. For dissolved oxygen there is the DO803 luminescent optical DO electrode, an optical sensor rather than a membrane-based one, and the DO8032 replacement electrode cap.

Match the electrode to the meter it will connect to and to the sample: a pointed tip for cheese, meat or soil, a standard bulb for liquids, and an optical DO sensor where frequent membrane changes are a nuisance. Replacement caps keep an optical DO electrode in service. Lancetech Limited can quote any Apera electrode or probe and confirm compatibility with your meter.
