SmartDip 450M is a pneumatically retractable electrode housing with long immersion length up to 250mm from mounting flange. This metal body model can be implemented in different chemical applications including tanks, vessels and reactors for In-situ measurements of parameters such as pH/ORP, Conductivity and Dissolved Oxygen. SmartDip 450M has a ball valve the most reliable and widely accepted isolating equipment for isolation in the service position. The user-friendly design makes it much easier to remove the sensor from the housing for calibration.
