Frequently Asked Questions

• What is the lowest H₂S level this sensor can detect?
  • 1 ppm is the lower detectable limit.
• Can I change the full scale range after installation?
  • Yes, you can select 50 to 500 ppm via software.
• How often should I calibrate the sensor?
  • Calibrate every 3–6 months for best accuracy.
• Does it work in freezing temperatures?
  • Yes, it operates from -40°C to 55°C.

Selection Guide

• Choose range based on your max expected H₂S level.
• For low-level areas, select 50 ppm range for better resolution.
• For high-risk zones, use 500 ppm to avoid saturation.
• Check operating temperature before installation.
• Use the default 100 ppm if you are unsure.
• Order spare calibration gas for routine checks.
