Hach Orbisphere Electrochemical Oxygen (O₂) Sensor, PEEK, 20 bar, EPDM O-Ring

Product #: 31110.02

Unit Price Contact Hach

Guard Ring Electrode Design

An auxiliary guard ring electrode surrounds the working electrode to shield against the influence of other gases and improve stability.

Rugged Construction

Use for harsh chemicals, hot CIP and high pressure situations.

Flexibility

Installs in-line for process control, or in flow chamber for spot measurement. Cable detaches at sensor end for installation and maintenance flexibility.

From trace levels to super saturation
