The original maintenance-free optical oxygen sensor for power plants.
The Orbisphere K1100 is a high accuracy Luminescent Dissolved Oxygen Sensor optimized for power industry application. Since 1978, Hach Orbisphere LDO analyzers have set the industry standard for oxygen measurement by delivering confidence to every water chemistry manager. Together with the Orbisphere 410 single channel controller and the Orbisphere 510 multichannel controller, offers a new way of monitoring oxygen in power plants. Orbisphere dissolved oxygen sensors set the industry standards for oxygen measurement by offering peace of mind to every water chemist. The absence of membrane and electrolyte means that the sensor accuracy is unaffected by process changes such as changes in flow. The K1100 dissolved oxygen analyzer maintains this tradition and offers significant operating and cost benefits.
