PRODUCT DESCRIPTION

RK500-12 ORP sensor is simple and cost effective solution for a wide variety of waste water and process applications.
This all-in-one sensor provides simultaneous measurement of ORP and temperature.

The rugged Ryton body is designed for easy installation into on-line via the 3/4 inch tapered threaded connections provided on both ends of the sensor.

The wide body sensors (26 mm diameter) hold four separate elements in one unbreakable Ryton body, large volume gelled electrolyte and the double junction reference system slows down depletion and poisoning extending the life time.
