SB-4VOC-500 (VOC)

Electrochemical VOC Sensor (0~500 ppm, iso-butylene)

SB-4VOC-500 is an electrochemical sensor capable of detecting various volatile organic compounds (VOCs) within a 0–500 ppm range based on iso-butylene. It provides linear output, high resolution below 3 ppm (based on iso-butylene), and a fast response time of less than T90 30 seconds. The sensor is suitable for both portable and fixed gas detection devices, operates stably across a wide temperature range, and offers a lifespan of more than 24 months in ambient air.

KEY FEATURES
    • Sensor Type: Electrochemical VOC sensor
    • Measurement Range: 0–500 ppm (based on iso-butylene)
    • Sensitivity: 250 ± 50 nA / ppm
    • Response Time: T90 < 30 sec
    • Resolution: < 1 ppm
    • Operating Life: ≥ 24 months in ambient air
    • Operating Temperature: -20℃ to +50℃
