Macurco OX replacement oxygen sensor cartridge for the OX-6 fixed oxygen deficiency and enrichment detector.

Key features

• Electrochemical oxygen sensor cartridge sized to drop into the OX-6 detector housing without rewiring
• Used to restore O2 detection capability after sensor end-of-life notification from the host device
• Field-replaceable design allows maintenance staff to swap the sensor without removing the detector body from the wall
• Calibration with span gas is required after replacement to validate accuracy across the 0 to 25 percent O2 range
• Typical service life is 2 to 3 years depending on ambient conditions and gas exposure history

The Macurco OX sensor is the replacement electrochemical cell for the OX-6 oxygen detector used in commercial refrigeration machine rooms, confined space monitoring stations, and ASHRAE 15 compliance installations. Electrochemical O2 sensors have a finite service life because the internal electrolyte consumes during operation; the OX-6 reports end-of-life via its LED display and host system relay. Replacement triggers a recalibration cycle with a known span gas (typically 100 percent N2 for zero check and ambient air for span check). Confirm the host detector model before ordering, since other Macurco O2 cell variants are not interchangeable.

Verify panel/device family compatibility before ordering.
