Honeywell Analytics E3M Sensor Cartridge

The Honeywell Analytics E3M Sensor Cartridge (Order Number: 1309A0040) is a critical genuine OEM replacement for maintaining the E3 Point Gas Detection System. Professional installers recognize this CH4 gas sensor cartridge for its plug-and-play architecture, allowing for field replacement without the need for complex recalibration or system overhauls. Built with high-grade catalytic combustion technology, it provides a detection range of 0 to 100% LEL with a precise 0.5% LEL resolution. This makes it an essential component for industrial methane monitoring in parking garages, wastewater treatment facilities, and boiler rooms. The E3M is fully compatible with both E3Point Standalone (E2SA) and Network (E3SM) monitors, ensuring seamless integration into existing safety protocols. Its rugged design thrives in environments ranging from -40° to 122°F, providing stable 4-20 mA current output for real-time data logging and alarm triggering.

Key Benefits for HVACR Contractors:

• Universal Compatibility: Direct replacement for part number 1309A0040, fitting both standalone and networked E3 Point units.
• Pre-Calibrated Precision: Each Honeywell E3M sensor arrives factory-calibrated, significantly reducing commission time and labor costs.
• Extreme Environment Tolerance: Engineered to operate reliably between -40°C and 50°C, ideal for unconditioned mechanical spaces.
• High-Resolution Safety: Offers a 0-100% LEL range for Methane (CH4), providing early warning for combustible gas accumulation.
• Seamless Installation: Features a robust pin-connector design for rapid smart sensor cartridge swapping with minimal system downtime.

Common Questions & Technical Support:

Is the E3M cartridge hot-swappable?
No. You must remove all power from the E3 Point base unit before extracting the old cartridge and inserting the E3M replacement to prevent damage to the PCB pins.

Does this sensor detect Propane as well?
The E3M is specifically calibrated for Methane (CH4). For propane applications, you must use the E3P (1309A0038) sensor cartridge to ensure accurate LEL readings.

What is the recommended installation height?
Since methane is lighter than air, the E3 Point monitor housing this CH4 sensor should be mounted approximately 1 foot (30 cm) from the ceiling near potential leak sources.
