SS11VC (C₂H₃Cl) Electrochemical Vinyl Chloride Sensor (0–20ppm)

The SS11VC is an electrochemical sensor designed to detect vinyl chloride (C₂H₃Cl) within the 0–20 ppm range. It delivers an output of 450 ± 100 nA/ppm with a T90 response time under 70 seconds. The sensor features a resolution of ≤0.5 ppm and repeatability within ±5%, allowing for accurate measurements. With low cross-sensitivity to CO, H₂, and NH₃, the SS11VC ensures stable operation even in complex environments. It is ideal for use in PVC manufacturing, chemical plants, and fixed industrial gas monitoring systems. The sensor supports an operating temperature range of -20℃ to +50℃ and offers a lifespan exceeding 24 months in air.
