XES: Aspirated Multi-Gas Detection Across the Field
50,000 Field Hours with FEI Across Construction, Wellhead, Landfill, and Residential Safety Deployments
Partner: Field Environmental Instruments (FEI) · Industry: Environmental
Rental fleets face a different reliability bar than fixed installations: equipment moves from job to job, environment to environment, and has to perform consistently without the luxury of a controlled, single-site deployment. Safeguard Analytics' XES aspirated multi-gas detection system has been put through exactly that test. Deployed by Field Environmental Instruments (FEI) across a rotating portfolio of projects - construction sites, oil and gas wellhead monitoring, landfill emissions and odor tracking, and residential safety validation near environmental hazards - the XES has logged 50,000 cumulative field hours with only isolated, minor component issues and no failures in its core sensor chambers or pump. Safeguard Analytics is built on decades of industrial gas detection engineering, carried forward by a founding team with over 45 years of field-proven design experience.
Technology overview
The XES is an aspirated gas detection system available in 2-, 4-, or 6-sensor cell configurations, drawing air samples through the unit for active analysis rather than relying on passive diffusion. Depending on the application, XES units are configured with electrochemical, NDIR, or PID sensor technology - enabling detection ranges from parts-per-million (PPM) down to parts-per-billion (PPB). This flexibility allows the same platform to serve construction site safety monitoring, oil and gas wellhead surveillance, landfill emissions tracking, and community-adjacent hazard monitoring, each configured to the sensitivity the application demands.
Deployments
The 50,000 hours reflected here span multiple independent rental engagements through FEI. Project-level detail is limited by customer confidentiality and non-disclosure agreements; individual project deep-dives will follow as separate case studies.
Construction
Active job-site gas monitoring supporting worker safety programs.
Oil & Gas Wellhead Monitoring
Surveillance of wellhead operations for hazardous gas presence.
Landfill Monitoring
Tracking emissions, odor, and pollutant migration toward nearby residential areas.
Residential Safety Validation
Monitoring near environmental hazards to confirm safe conditions for nearby communities.

| Detection range | PPM down to PPB, application-dependent |
| Rental partner | Field Environmental Instruments (FEI) |
Lessons learned
- Parts-per-billion level monitoring demands a rigorous, consistent measurement process - small deviations in handling or setup carry a proportionally larger impact on data integrity at that sensitivity.
- Readings at this sensitivity are more susceptible to temperature and humidity influence; field deployments require active compensation and adjustment in data representation to preserve accuracy where those conditions are present.
- Because methodology varies by project type and objective, standardizing data consistency protocols - independent of the specific environment - has been essential to maintaining reliable results across a diverse rental portfolio.
Conclusion
Across 50,000 field hours and a wide range of project types deployed through FEI, the XES has demonstrated consistent reliability with only isolated, minor component issues - and no failures in its core sensor chambers or pump. Whether supporting construction safety, wellhead surveillance, landfill emissions tracking, or residential hazard validation, the XES platform delivers the flexibility and durability rental operations demand.
