Advanced modular portable gas detection platform

    A configurable platform designed to support gas detection across a wide range of applications, from broad hazard screening to compound-specific analysis. Rethinking gas detection for modern operations. Industrial environments are becoming more complex, and so are gas detection requirements. Many organisations rely on multiple devices to identify unknown hazards, measure compounds and support compliance workflows. This can increase complexity across operations, maintenance and training.

      Detection needs vary, from identifying unknown hazards to measuring compounds at trace levels. Traditional, single-purpose devices often require multiple tools, workflows and systems to address these challenges.

        Honeywell’s ModRAE™ ModRAE is a modular gas detection platform designed to support configurable detection across a range of industrial applications. Its cartridge-based architecture enables teams to align detection capabilities with specific monitoring requirements.

          From soil remediation and fumigation to industrial operations and emergency response scenarios, ModRAE supports a range of monitoring needs, helping improve visibility into environmental conditions while supporting operational continuity.

            True modularity for dynamic applications ModRAE is built to support demanding environments. ModRAE enables faster configuration, more consistent workflows, and greater flexibility as operational requirements evolve.

              Interchangeable smart cartridges enable rapid field changes through a quick-release mechanism, letting users adjust sensing configurations at the point of use with minimal disruption.

                Whether transitioning from broad VOC screening to targeted chemical measurement, the system adapts through cartridge selection, rather than full device replacement. Cartridges can be removed and managed independently, enabling calibration, servicing, and storage without requiring full device disassembly, helping reduce downtime. Each cartridge incorporates an integrated SensorRAE, helping maintain sensor readiness even when removed from devices. This reduces the need for separate external sensor management systems and allows cartridges to remain operational during transport, storage or servicing.

              Configure detection to match your application

                Supports diverse applications: Designed to support a wide range of use cases, from soil remediation and fumigation to industrial hygiene and confined space, enabling flexibility across changing monitoring requirements.

                  Connected and integrated operations: Supports multiple wireless communication approaches to enable remote and real-time monitoring, improve visibility into field conditions and support centralised data management across operations.

                    Integrated with Safety Suite 2.0: Designed to integrate with Honeywell Safety Suite 2.0, enabling centralised device management, visibility into monitoring data and more informed decision-making across connected operations.

                      Enhanced serviceability: Cartridge-based architecture supports efficient maintenance and simplified workflows by enabling independent servicing, calibration, and handling of sensing components.

                        Modular configuration: Interchangeable smart cartridges support fast adjustment of detection capabilities with reduced disruption. The modular design also enables simple wireless upgrades through field installation of a wireless module, helping reduce downtime, service costs, and upgrade effort.

                          Streamlined user interaction: Designed to support guided workflows and consistent operation, helping reduce variability across users and improve efficiency in the field.

                            Honeywell ModRAE Features & Benefits

                          ▪ Scalable design - ModRAE is designed to support evolving operational and regulatory requirements, enabling organisations to adapt gas detection capabilities as conditions change. Its modular architecture supports quick cartridge replacement, wireless connectivity upgrades, and other enhancements without requiring full device replacement.

                            ▪ Advanced gas and chemical detection - Supports a broad range of gas monitoring applications, from VOC screening and total VOC measurement to compound-specific detection such as benzene, enabling teams to address evolving monitoring requirements within a single platform.

                              ▪ Flexible connectivity - ModRAE supports multiple wireless protocols to enable real-time remote monitoring and centralised visibility across operations. Connectivity options such as cellular, Wi-Fi, LoRa, Mesh, BLE and NFC support flexible deployment and device configuration.

                                ▪ Decision-ready interface - ModRAE features a high-visibility colour display with intuitive, colour-coded alerts to help users quickly interpret gas conditions and respond in real time. Its award-winning interface design, combined with integrated guidance and access to key metrics such as TWA and STEL, supports faster, more consistent decisions.

                                  ▪ Continuous readiness - Each ModRAE cartridge integrates SensorRAE technology to help maintain sensor readiness independently of the device. Cartridges can be stored, transported or serviced while supporting flexible maintenance and faster deployment.

                                    ▪ Adaptable workflows - ModRAE features Health Mode for continuous monitoring with exposure metrics such as TWA and STEL, and Safety Mode for targeted investigation. Safety Mode supports survey detection with real-time graphing and object measurement for consistent, repeatable sampling across applications.

                                        The future of detection isn’t just more devices. It’s a better system.

                                          Advanced gas detection has expanded significantly over time. New sensors, workflows and measurement techniques have made detection programs more capable and more specialised.

                                            What’s changing now is not whether advanced detection is necessary; it’s how it’s structured. Honeywell ModRAE is designed to support a more continuous, configurable approach, aligned with how work is performed across industrial hygiene, safety and response applications. Advanced detection isn’t incomplete; it’s just not yet connected. ModRAE helps bring those pieces together!
