pH SENSOR - AQPH-E1B1Z.

The AQUAMATIC "SPECTRA" pH sensor AQPH-E1B1Z offers the most advanced design of pH glass electrodes available.

The sensing element consists of a unique peripheral Porous Teflon liquid junction with matched viscosity electrolyte combined with a specially formulated, low impedance glass membrane which permits this sensor to be used in the broadest spectrum of pH applications.

Features include a pressure stable and waterproof construction designed for easy maintenance. Small dimensions, good linearity, high accuracy and good long time stability. Isopotential point at pH 7.00 + 0.02 - The construction permits extended periods of pH measurements where the presence of "POISONING ION" or "MEMBRANE LEECHING" conditions exist which will shorten life of a conventional electrode.
