Frequently Asked Questions

• What is the default full scale range?
  • Default is 15.0 ppm, but you can choose 5.0–20.0 ppm.
• Can I calibrate with a gas different from the default?
  • Yes, use cal gas between 30% and 70% of your selected range.
• Is this sensor suitable for outdoor use?
  • Yes, it works from -40°C to 55°C, but protect from rain.
• What is the Lower Detectable Limit?
  • The LDL is 0.6 ppm – it can detect very low SO2 levels.
• How often should I replace the sensor?
  • Typical life is 2–3 years; replace when accuracy drifts.

Experience-based Q&A

• My reading is unstable. What should I check?
  • Check for moisture or dust on the sensor surface.
• Can I use this sensor for H2S detection?
  • No, this sensor is specifically for SO2 only.
• How do I store a spare sensor?
  • Keep in original packaging, at room temperature, dry place.

Buying Guide

• Choose the right full scale for your expected SO2 level.
• For low-concentration areas, 5.0 ppm range gives best resolution.
• Ensure your gas detector supports this sensor type.
• Order calibration gas along with the sensor for initial setup.
• Consider a spare sensor to avoid downtime during replacement.
