From trace levels to super saturation

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

Unrivalled detection limit of ±0.1 ppb or 100 ppt

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

Guard Ring Electrode design improves speed of response and reduces interferences

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

Installs in-line for process control, or in flow chamber for spot measurement

Unrivalled detection limit of ± 0.1 ppb or 100 ppt

What's included?

Sensor and manual.
Controller, sensor cable, flow-chamber or process connection must be ordered separately.
