Frequently Asked Questions (FAQ)

• Does the XNXO1SS directly replace the S3KO1SS?
  Yes, the XNXO1SS is the direct replacement for the older S3KO1SS oxygen sensor cartridge. It fits the same cradle and uses the same connector.
• Is this sensor brand new and original Honeywell?
  Absolutely. We supply 100% new, genuine Honeywell XNXO1SS cartridges with full factory calibration.
• Can I use this with my Series 3000 MkII transmitter?
  Yes, the XNXO1SS works with XNX, Series 3000 MkII, and MkIII transmitters without any modifications.
• What is the measurement range for oxygen?
  The sensor measures oxygen from 0 to 25% v/v, which covers both deficiency and enrichment monitoring.
• How long does shipping take?
  We dispatch within 5 business days via FedEx, UPS, or DHL. Transit time depends on your location.
• What is the default calibration point?
  The default cal point is typically 12.5% v/v, but you can adjust it using 30-70% of full scale.
• Can I return the cartridge if I order the wrong one?
  Yes, we accept returns within 30 days, provided the cartridge remains unused and in original packaging.
• Is hot-swapping safe for this oxygen sensor?
