Description

The ARD 75 is a modular immersion holder for up to three pH, ORP, conductivity, or oxygen sensors. The fitting is suitable for measuring inside tanks, basins, and channels.

Customizable to Your Application Needs

The ARD 75 is available in many configurations to fit most application needs. The sensor holder is available in high-quality PP-H or PVDF and comes with process connection options of flange ANSI 2“ – 4“ with optional sliding flange bushing, wall holder, catenary suspension, or as a submersible version. You can also choose your immersion depth.

Easy Sensor Maintenance and Replacement

The ARD 75 design is easy to operate. Users can easily install or replace the sensors with just a ½ turn of a coupling nut on the sensor adapter. In addition, the retraction and rinse option effectively cleans the sensor without opening or dismantling the fitting when using an automated cleaning system like the CL-90.
