Orbisphere
Description
The Orbisphere K1200-S00H is a high-range luminescent dissolved oxygen (LDO) sensor designed for inline measurement of dissolved oxygen (O₂) with a range of 0 – 40 ppm. Utilizing optical luminescent technology, the sensor reduces drift and maintenance requirements compared to traditional electrochemical sensors. It is configured with a 28 mm Orbisphere fitting for easy integration into existing flow chambers or process connections. The sensor offers consistent performance under varying process conditions without frequent recalibration.
Features and Benefits of K1200-S00H
- High-range dissolved oxygen measurement up to 40 ppm — K1200-S00H.
- Luminescent dissolved oxygen (LDO) technology for minimal drift and extended calibration intervals.
- Maintenance-free optical design with no membranes or electrolyte.
- 28 mm Orbisphere fitting compatible with standard inline flow chambers.
- Designed for industrial water quality applications including boiler and steam cycle water.
Usage and Handling
The K1200-S00H sensor should be installed into an Orbisphere 28 mm inline flow chamber or equivalent process fitting and connected to a compatible Orbisphere controller. Follow manufacturer instructions for wiring, calibration and initial setup. Calibration typically uses zero (oxygen-free gas) and air reference points upon cap replacement. Maintenance is minimal, usually limited to an annual calibration. Store the sensor in original packaging until installation to avoid contamination.
