Honeywell 1309A0035 E3PT H2S Sensor Cartridge

Product Description

The HONEYWELL 1309A0035 is a replacement sensor cartridge for the E3PT fixed-point gas detector, designed to detect hydrogen sulfide (H2S) in hazardous and industrial environments. The cartridge outputs a current signal, making it compatible with standard 4-20 mA monitoring and control systems. It is designed for straightforward field replacement without requiring full instrument replacement, reducing downtime during maintenance cycles. Licensed gas detection technicians, industrial hygienists, and instrumentation technicians are the primary installers for this type of cartridge.

This sensor cartridge is suited for fixed gas detection applications across a range of industries including oil and gas production, mining operations, agricultural facilities, transportation hubs, industrial laboratories, and general manufacturing environments where H2S exposure is a hazard. It is intended for use within the HONEYWELL E3PT detector platform and is installed as a maintenance replacement when the active sensor element reaches end of service life or fails calibration.

Key Features

• Detects hydrogen sulfide (H2S) gas for fixed-point safety monitoring
• Current signal output for integration with 4-20 mA control and monitoring systems
• Cartridge-style form factor supports field replacement without full instrument swap
• Suited for industrial, oil and gas, mining, agricultural, transportation, and laboratory environments

Compatibility

Designed as a replacement sensor cartridge for the HONEYWELL E3PT fixed-point gas detection platform, for use in H2S detection applications.

Installation Notes

Sensor cartridge replacement should be performed by a qualified instrumentation technician or licensed gas detection service professional. De-energize or place the detection system in maintenance bypass mode before removing the spent cartridge to prevent false alarms or control actions. Follow the instrument manufacturer's calibration procedure after installing a new cartridge, as fresh sensors require a stabilization period before the unit is returned to active service. Comply with applicable site safety and confined-space entry requirements when servicing detectors located in hazardous areas.
