SB-4ClO₂-1 (ClO₂)

Electrochemical Chlorine Dioxide (ClO₂) Sensor (0–1 ppm)

Product Description

The SB-4ClO₂-1 is an electrochemical gas sensor designed for precise detection of chlorine dioxide (ClO₂) within the range of 0 to 1 ppm. It is suitable for both portable and fixed gas detection devices, offering linear output characteristics and excellent stability. With a fast T90 response time of less than 30 seconds, the sensor ensures reliable ClO₂ detection across various industrial applications. It operates stably over a wide temperature range from -20℃ to +50℃ and provides an expected operating life of more than 24 months in ambient air.
