Orbisphere K1200, Luminescent Oxygen Sensor - Nuclear version

Orbisphere K1200, Luminescent Oxygen Sensor - Nuclear version
Product #: K1200-S00
Unit Price Contact Hach

One calibration per year

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.

No membranes = two minutes of maintenance

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.

Low cost retrofit

The complete system consists of a Controller, a flow chamber, the K1200 Luminescent Dissolved Oxygen Sensor and a 312xx Hydrogen Sensor for parallel measurement. The sensor is compatible with Hach Orbisphere 28 mm flow chambers, eliminating the need for engineering changes. The installation is fast and easy and does not require special preparation.

A new level of confidence

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.
