Eutech’s pHion and ORPion electrodes are most ideal for general-purpose field and indoor measurements as these epoxy body electrodes are less brittle than glass electrodes.  These electrodes do not require extra maintenance.  Moreover, these electrodes do not break on fall unlike glass body electrodes.
