One calibration per year

One zero point calibration per year is all that is needed with the K1100 sensor, unlike traditional electrochemical (EC) sensors, which display significant drift after only a few months and demand regular re-calibration and substantial operator time.

Low Cost Retrofit for existing Orbisphere EC sensor

The complete system consists of a 410 Controller, a flow chamber and the K1100 Luminescent Dissolved Oxygen Sensor. The sensor is compatible with Hach Orbisphere 28 mm flow chambers previously used with EC sensors.

The K1100 optical sensor is the first to use luminescent measurement technology to measure low level oxygen in power plants. Since 1978, when the first patent on EC sensors was granted, Hach Orbisphere sensors have set the industry standard for oxygen measurement at ppb level.
