SO2‑A4F Sulphur Dioxide Sensor
SO2 Gas Sensor, Electrochemical, A‑Series, Filtered PPB-Level
Enhanced selectivity SO2 sensing with PPB‑level resolution for environmental monitoring
Based on the proven SO2‑A4 PPB‑level platform, the SO2‑A4F adds targeted filtering to reduce cross‑sensitivities and improve performance. Its A-Series 4-electrode format is widely used in portable and handheld air-quality instruments requiring accurate low-level SO2 detection.
