CAT Water Chemistry Controller Sensor (ORP)The performance of any chemical controller is only as good as the signals generated by the pH and ORP sensors. The new CAT & Hayward heavy-duty sensors are the product of more than seven years research and development. Our new design incorporate the latest technology such as dry-polymer electrolyte for extremely long life and patented Porous Teflon reference suction for low maintenance. CAT heavy-duty electrodes are a direct upgrade for all common pH and ORP controllers. Hayward Item Code: PRO25-10, PRO25-2, PRO25-AU-10, and PRO25-AU-2FeaturesLow-Noise Specialty Cable – CAT pH and ORP sensors utilize a 24 highly specialized, low leakage cable which ensures clean signal transmission while filtering the noise and interference commonly found in equipment rooms. The standard BNC connector is covered by a colour-coded boot. High Capacity 1/2″ NPT Molded Body – Durable custom injection molded body provides protection for the interior components while incorporating a standard 1/2″ NPT wet end. Reference Element – CAT sensors are constructed as combination electrodes. Each sensor is actually comprised of a reference half-cell and a measurement half-cell, so no additional reference electrode is required. Dry-Polymer Electrolyte – Formulated to provide extended service life and high resistance to bacteriological contamination. Teflon Reference Junction – Revolutionary in the sensor field, the special porous teflon material resists fowling and is easily cleaned with a soft brush and a degreasing cleanser such as 409. Mineral deposits can be removed with a mild acid solution.
