Frequently Asked Questions (FAQ)

• Q: Is this sensor compatible with the XNX transmitter?
  Yes, the XNXXSG1SS directly replaces the hydrogen sensor in XNX and Series 3000 MkII/MkIII.
• Q: What is the detection range for hydrogen?
  It detects H₂ from 0 to 1,000 ppm with a 30 ppm lower limit.
• Q: Can I calibrate this sensor in the field?
  Yes, you can use 30-70% of full scale (default 500 ppm) for calibration.
• Q: What is the typical response time?
  T50 is under 60 seconds, and T90 under 90 seconds.
• Q: Does this sensor require powering down the transmitter?
  No, the smart design supports hot-swapping without disconnecting power.
• Q: What is the operating temperature range?
  It works from -20°C to +55°C (-4°F to 131°F).
• Q: Do you have stock available?
  Yes, we maintain ample stock for immediate shipment.
• Q: What is your return policy?
  We support 30-day returns on unused, original-condition units.
