S425 pH/ORP Sensor 1″ Threads & Extended Insertion

Application

In-Line & Submersion

Maximum Flow Rate

10 ft (3 m) per second

Chemical-resistant Wetted Materials

These high quality sensors are constructed of corrosion-resistant wetted materials including Ryton®, Teflon® and glass.

Coaxial Porous Teflon® Reference Junction

The large annular junction resists fouling. Also, the sealed, double-junction reference electrode is highly resistant to poisoning.
