4S Rev. 2 CiTiceL Sulfur Dioxide Sensor (SO2 Sensor) Key Features & Benefits: * Industry leading reliability * Improved performance variability 4S Rev. 2 CiTiceL Sulfur Dioxide Sensor (SO2 Sensor) Technical Specifications * Operating Principle: 3-electrode electrochemical * Measurement Range: 0-20 ppm SO2 * Maximum Overload: 150 ppm SO2 * Filter: To remove H2S * Sensitivity: 0.5 ± 0.1 µA/ppm * Response Time (T90): < 25 Seconds at 20 deg C * Repeatability: < ±2% of signal * Recommended Storage Temp: 0 - 20 deg C * Operating Humidity: 15% to 90%RH non-condensing Poisoning CiTiceLs are designed for operation in a wide range of environments and harsh conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments, and operation. When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic.
