The first maintenance-free optical oxygen sensor for nuclear power plants.
The Hach Orbisphere K1200 sensor is a high accuracy Luminescent Dissolved Oxygen (LDO) sensor that has been optimized for measurements in water processes in the power and steam industry.
Designed for mechanical robustness to extend service life and optimize total cost of ownership, the sensor, combined with the Orbisphere Controllers, offers a new way to monitor dissolved oxygen in power plants. Based on good engineering practice the Orbisphere K1200 LDO sensor is suitable for nuclear plant application.
Maintenance and operating costs are significantly reduced due to the absence of membrane and electrolyte and sensor accuracy is unaffected by process changes such as flow changes.
