WTW SenTix® Special pH Electrodes
Special samples need special electrodes. SenTix® special electrodes can take on the challenges associated with measuring the pH value of surfaces, solids, suspensions, emulsions, low ionic samples, smallest volumes and more. For those who require a non-glass electrode: The SenTix® FET can be used with every WTW pH meter.

SenTix® quality electrodes by WTW - convenient measurement and precision.

Low-resistance glass membranes guarantee stable measuring signals even at low temperatures.
Silver ion-free reference electrolyte, together with the proven platinum wire diaphragm, prevent measurement problems by precipitating silver compounds.
Functional slide for accessing the refill opening for electrodes with liquid electrolyte.
Connectors: Waterproof DIN connector, BNC connector, fixed cable (1 or 3 m, 3 ft. or 9 ft.) or plug head (S7 or SMEK).
