The Orbisphere 1100 series optical dissolved oxygen sensor from Hach Lange is helping Serco to solve corrosion problems within the UK power generation sector.

The instrumentation has helped reduce maintenance time and service requirements to improve the overall monitoring efficiency of testing carried out under plant conditions.

The sensor is used to monitor feedwater for the determination of dissolved oxygen levels in ultra pure water, in this instance, primary coolant in pressurised water reactors.

Employing luminescent measurement technology, with no membranes or electrolyte, the solid state sensor head of the Orbisphere 1100 is unaffected by process changes or pressure shocks and requires minimal user intervention.

Annual maintenance is limited to just a few minutes for a zero point calibration.

In addition, chemicals are not required for this process, making the task easier and safer without reducing measurement precision.

A further feature of the luminescent measurement technology is the elimination of effects on readings by other dissolved gases such as carbon dioxide and hydrogen.

The sensor will fit into any existing Orbisphere sensor housings, allowing quick and reliable monitoring, even at sub-5ppb levels, making the instrument suitable for all power applications.

The sensor is then connected to the Orbisphere 510 – Multi Channel O2, O3, CO2, N2 and H2 Gas Analyser and Orbisphere 410 – Oxygen and Ozone Gas Analyser.
