Using the oxygen module, the IKS aquastar can continuously measure and regulate the oxygen content in your fresh and seawater aquarium. And while it is doing so, you can have the oxygen content displayed in mg/l or the oxygen saturation in %. As the module is galvanically separated from the basic system, the oxygen content can be measured at different points in a water circuit without the individual sensors having an effect on each other.Technical data iks Oxygen module with optical sensor ODOS:Measuring range from 0 to 150%, from 0 to 20 mg/lTemperature range 0 to 50CAccuracy when exposed to a flow of 2 cm/s ca. 5% below the real figureAccuracy when exposed to a flow of 5 cm/s ca. 1% below the real figureSwitch hysteresis 2%High-quality, low-maintenance Clark-measuring cellsLong sensor life (physically 2 years)Calibration apperatus for precise calibrationAutomatic or manual temperature compensationUp to eight control processes can be programmedUpper and lower alarm setting
