Product Number: K1200-S00H
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.
One zero point calibration per year is all that is needed with the K1200 sensor. Traditional electrochemical (EC) sensors display significant drift after only a few months, demanding regular re-calibration and substantial operator time. Due to its luminescent technology, the K1200 sensor is designed for minimal drift, resulting in it being the most stable sensor with the longest calibration interval in the nuclear industry.
With no membranes to replace and no electrolyte solution to replenish, the K1200 is virtually maintenance-free requiring only two minutes of maintenance per year. Sensor accuracy is unaffected by process changes or low flow events with no polarization time, eliminating
unnecessary operator interventions in radioactive zones. In addition, corrosive or hazardous chemicals are not required, making the annual task faster, easier and safer without reducing measurement precision.
The complete system consists of a 510 Controller, cable, and the K1200 Luminescent Dissolved Oxygen Sensor. The sensor is compatible with Hach Orbisphere 28 mm flow chambers previously used with EC sensors, eliminating the need for engineering changes to weld, add, and test new connections - an ideal retrofit. The installation is fast and easy and does not require special preparation. The plug-and-play sensor is ready immediately ready for measurement.
The K1200 optical sensor is the first to use luminescent measurement technology to measure low level oxygen in nuclear power plants. Since 1978, when the first patent on EC sensors was granted, Hach Orbisphere sensors have set the industry standard for oxygen measurement by delivering confidence to every water chemistry manager. The new K1200 maintains this tradition in the nuclear industry and offers significant operating and cost benefits.
