Honeywell Analytics E3NO2 Sensor Cartridge

The Honeywell Analytics E3NO2 Sensor Cartridge is a professional-grade replacement component engineered specifically for the E3Point Gas Detection System. This toxic gas sensor is cross-compatible with several legacy units, as the E3NO2 is identical to 1309A0037 and effectively serves as a high-performance replacement for the 201T and 301M series integrations. Designed for commercial parking garage gas detection and mechanical room monitoring, this "smart sensor" features a 0 to 10 ppm detection range with 0.1 ppm resolution. Utilizing pre-calibrated electrochemical technology, it features Plug-n-Play gas sensor functionality, allowing for field replacement without the immediate need for complex bench calibration. The unit operates reliably in extreme conditions, maintaining mechanical integrity from -40° to 122°F. By integrating Demand Control Ventilation (DCV) through your BAS, these cartridges help optimize fan run-times and reduce operational costs in Honeywell E3Point Network Single Gas Monitor E3_M or standalone E3SA configurations.

• Universal Compatibility: Fully compatible with Honeywell E3Point series monitors, including standalone, network, and remote configurations.
• Pre-Calibrated Precision: Factory-calibrated "smart cartridge" design ensures accurate nitrogen dioxide monitoring immediately upon installation.
• Simplified Maintenance: The 1309A0037 nitrogen dioxide sensor utilizes a keyed, pin-base design for rapid field swaps, minimizing system downtime.
• Advanced Diagnostics: Works with the E3Point’s patented Reflex technology to continuously monitor sensor cell health and communicate fault status.
• Rugged Environmental Range: Rated for demanding mechanical environments with an operating temperature range of -40°C to 50°C.

How do I replace the Honeywell E3NO2 sensor cartridge?
Always power down the E3Point base unit before service. Pull the old replacement gas sensor straight out from the board and press the new cartridge firmly into the socket. Ensure the "TOP/HAUT" marking faces the top of the monitor to avoid bending the pins.

Can this sensor be used for dual-gas detection?
Yes. In a standalone E3Point configuration, you can use one internal E3NO2 cartridge and add a remote sensor to monitor a second location or a different gas type, such as Carbon Monoxide (CO).

At what height should this NO2 sensor be installed?
Nitrogen Dioxide (NO2) is typically heavier than air; however, hot exhaust from vehicles can rise. For standard garage applications, mount the sensor at breathing zone height or according to local building codes for the specific ventilation strategy.
