Sensitivity Characteristics The figure below represents typical sensitivity characteristics to dissolved oxygen in 25˚C water. The X-axis is indicated as dissolved oxygen concentration in water (mg/L). The Y-axis is indicated as sensor output voltage (mV). Temperature Dependency (typical) The figure below represents typical temperature dependency characteristics. The Y-axis is indicated as sensor output voltage (mV). The Maxell Dissolved Oxygen Sensor KDS-25B is a unique galvanic cell type sensor which was developed for water quality control. Its most notable features are long life expectancy and no influence by CO2. Features: * Long life * Virtually no influence from CO2 * No external power supply required for sensor operation * No warmup time is required Maxell Dissolved Oxygen Sensor KDS-25B Applications: * Water quality control PRODUCT INFORMATION 100 120 140 0 10 20 30 40 50 60 70 80 Output Voltage (mV) Dissolved Oxygen Concentration (mg/L) Max Min Typical 0 10 20 30 40 50 Output Voltage (mV) Temperature (˚C)
