Yokogawa PH97-07 Retractable Ph Sensor

Description:

The Yokogawa PH97-07 Retractable pH Sensor is used a rugged industrial electrode designed for use with retractable assemblies (PH87 series) to enable continuous pH measurement in pressurized or flowing process environments. It features a durable Ryton body, integrated temperature element, and double-junction reference system for stable and long-life operation in harsh applications such as slurries and chemical processes. 

Applications:

The Yokogawa PH97-07 is used in industrial environments for continuous online monitoring of pH in liquid processes where retractable installation is required. It is commonly deployed in pulp and paper processing, chemical tanks, slurries, and pressurized pipelines. The retractable design allows safe removal and maintenance of the sensor without shutting down the process, ensuring continuous operation and reduced downtime.
