Honeywell Analytics E3SCO Sensor Cartridge

The Honeywell Analytics E3SCO Sensor Cartridge (equivalent to part number 1309A0038) is a critical component for maintaining safe air quality in high-traffic environments. Designed specifically for the Honeywell E3Point Gas Monitoring System, this electrochemical sensor provides precision detection of Carbon Monoxide (CO) within a default 0–225 ppm range, though it can be configured for ranges up to 250 ppm. Utilizing Smart Sensor technology, the E3SCO is factory-precalibrated, enabling immediate "plug-and-play" integration that simplifies field maintenance and reduces downtime for busy contractors.

This replacement CO cartridge is compatible with E3Point standalone (E3SA) and networked (E3SM) models. It facilitates Demand Control Ventilation (DCV) by signaling HVAC fans through 4-20 mA outputs, Modbus, or BACnet MS/TP protocols, ensuring carbon monoxide levels stay below hazardous thresholds in parking garages, mechanical rooms, and loading docks. The polycarbonate housing protects the internal Reflex technology, which a veteran tech knows is essential for continuous cell condition monitoring to prevent false alarms and ensure system integrity during critical events.

• Seamless Field Service: Snap-in design allows for hot-swappable replacement. Ensure the base unit is powered down before installation to avoid pin damage and allow for auto-configuration.
• Industrial-Grade Detection: High-accuracy electrochemical sensing with a resolution of 1 ppm, ideal for meeting OSHA and local building code requirements.
• Network Integration: Fully supports dual-gas monitoring when paired with a remote sensor on E3Point standalone units, streamlining multi-point detection.
• Operational Versatility: Engineered to function in rigorous environments ranging from -4°F to 122°F (-20°C to 50°C), perfect for unconditioned commercial spaces.

Is the E3SCO cartridge interchangeable with other E3Point sensors?
While the physical cartridge format is consistent across the series, the E3SCO is specifically calibrated for Carbon Monoxide detection. For monitoring Hydrogen (H2) or Nitrogen Dioxide (NO2), you must use the specific compatible cartridge for that gas type.

Does this cartridge require manual calibration upon installation?
No, these CO sensor cartridges are shipped factory-calibrated. The E3Point base unit will automatically recognize the new cartridge and sync the gas type and range settings.

How do I verify if my sensor needs replacement?
The E3Point system performs self-diagnostics. If the display shows Error 09 or 15, or if the maintenance log indicates the sensor has reached the end of its typical 6-year field life, it is time for a new 1309A0038 assembly.
