AMETEK Brookfield Jerome J405 Fixed Monitoring Mercury Vapour Analyser
Continuous mercury vapour monitoring for industrial sites, with integrated enclosure, alarms, and system outputs.
Key highlights
- Continuous mercury monitoring: Provides automated, long-term measurement for site safety and compliance.
- Complete system solution: Combines analyser, enclosure, alarms, and outputs in one integrated unit.
- Gold film sensor technology: Proven method for selective, repeatable mercury vapour detection.
- Outdoor-ready enclosure: IP-rated housing with temperature control for harsh environments.
- Local alarm indication: Visual beacons provide immediate status and alarm visibility.
- Removable analyser capability: Enables portable surveys to locate contamination sources.
The AMETEK Brookfield Jerome J405 Fixed Monitoring Mercury Vapour Analyser is a complete system designed for continuous, unattended measurement of mercury vapour in industrial and environmental applications.
Used where ongoing monitoring is required, the system provides reliable measurement of mercury concentrations for compliance, safety, and perimeter monitoring. It is typically deployed in locations where manual sampling is not practical or where continuous visibility of site conditions is essential.
The system is configured to suit the application, with enclosure design, sampling system, power supply, alarms, and communication outputs specified based on site requirements. This ensures the monitoring solution aligns with installation conditions, environmental exposure, and data integration needs.
The system integrates the Jerome J405 analyser within a robust environmental enclosure, incorporating temperature control, local display, alarm beacons, and communication outputs. This enables reliable operation in outdoor and exposed environments, with flexible installation on walls, poles, fences, or dedicated structures.
Unlike portable instruments used for spot checks, this system is designed for continuous operation, automatically sampling at defined intervals and providing ongoing indication of mercury levels. Multiple units can be deployed across a site to support perimeter monitoring or area-based detection strategies.
A key advantage is the removable analyser design, allowing the J405 unit to be used for portable surveys to identify sources of mercury contamination. Once identified, the analyser can be returned to the enclosure for continuous monitoring and verification.
Key Features
- Automated sampling operation: Configurable sampling intervals enable unattended monitoring over extended periods.
- Environmental enclosure design: GRP IP-rated housing with internal temperature control supports reliable outdoor installation.
- Gold film sensor measurement: Selective detection method provides stable and repeatable mercury vapour readings.
- Integrated alarm functionality: Visual alarm and health status beacons provide clear on-site indication of system condition.
- 4–20 mA output integration: Enables connection to site monitoring systems, PLCs, or data acquisition platforms.
- Flexible mounting configuration: Suitable for installation on walls, poles, fences, or dedicated frames.
- Removable analyser operation: J405 unit can be removed for portable survey use and reinstalled for continuous monitoring.
- Local display interface: Illuminated display provides clear visibility of readings and system status.
