Honeywell 1309a0037 NO2 Replacement Sensor E3point

Product Description

The HONEYWELL 1309a0037 is a nitrogen dioxide (NO2) replacement sensor cartridge designed for use with the Honeywell Analytics E3Point line of toxic and combustible gas monitors. This field-replaceable cartridge installs directly inside the E3Point monitor housing, restoring detection capability without replacing the entire unit. The sensor operates across a wide temperature range of -40 to 50 degrees C (-40 to 122 degrees F), making it suitable for demanding indoor and outdoor environments. Installation is performed by licensed technicians or qualified gas detection service professionals familiar with fixed-point gas monitoring equipment.

This sensor cartridge is intended for facilities and applications where nitrogen dioxide monitoring is required, including parking garages, boiler rooms, confined spaces, and industrial environments with combustion or exhaust exposure. The E3Point monitor platform is commonly deployed in commercial and light industrial settings where continuous toxic gas detection is a code or safety requirement. Replacement of the sensor cartridge is a routine maintenance task performed on a scheduled basis to maintain detector accuracy and regulatory compliance.

Compatibility

Designed as a replacement sensor cartridge for the Honeywell Analytics E3Point line of Toxic and Combustible Monitors. Verify the installed E3Point monitor is configured for NO2 detection before ordering.

Installation Notes

Remove power from the E3Point monitor completely before installing this sensor cartridge. Installation should be performed by a qualified technician familiar with fixed-point gas detection systems and applicable facility safety protocols. After reinstalling power, allow adequate sensor warm-up and stabilization time before returning the monitor to service. Verify detector readings and alarm setpoints following sensor replacement per the monitor manufacturer's commissioning procedure.
