G8 Portable, 1 to 5 Gas Detector
G8 portable gas detector is the most connected safety wearable ever made—helping teams stay safer and get more done in one scalable platform.
G8 delivers advanced gas detection in a rugged, intrinsically safe device designed to perform in the most demanding environments.
With swappable cartridges and coverage for virtually any gas your team may encounter, G8 provides reliable protection without slowing work down.
And it does so much more than detect gases.
G8 combines real-time alerts, built-in radio communication, and direct-to-cloud data to keep workers safe while improving visibility, response, and productivity across every site
Connected Gas Detection
Protect your people from gas exposures with a portable detector that’s built for how they work:
- Detect up to 5 gases simultaneously from 20+ sensors, with optional pump to easily switch between pre-entry and continuous gas monitoring.
- Advanced 4G LTE cellular connectivity with auto-switching between major carriers for the best coverage.
- Swappable cartridges to adapt to any situation (lone worker, single-gas, multi-gas, or multi-gas pump).
- Sensor readings to monitor the latest gas data, spot elevated readings sooner and act faster.
- Configurable alert thresholds to align with site policies, regulatory requirements, and job-specific risk profiles.
- Field-optimized, industrial design with a bright display and quick-access flashlight for demanding work environments.
Monitoring and Wareness
Always know where your people are, what they’re facing, and when something changes—so you can respond quickly, confidently, and with the right information
- Dual-band GPS/GNSS to pinpoint worker location, ensure quick incident response, and to show when and where every alarm, event and near-miss takes place.
- Real-time alerts for time-weighted average (TWA), short-term exposure limit (STEL), high/low gas levels, bump tests, calibrations, falls, no-motion, missed check-ins, proximity-based events, and silent and emergency SOS.
- Direct-to-cloud data streaming from the field to Blackline Live for alert management and worksite visibility.
- 24/7 live monitoring through your own safety control center, Blackline’s in-house Safety Operations Center (SOC), or our global Alarm Receiving Center (ARC) partners.
Human-to-Human Communication
Three ways to communicate in one device means your people can get help quickly and work together better with:
- Emergency Voice with a real person checking in when an alert is triggered and sending immediate help if needed.*(*connects to your own control room or Blackline’s 24/7 live monitoring service)
- Push-to-Talk works just like a two-way radio, using a dedicated button for clear audio and optional remote speaker mic (RSM) rivaling any industrial radio — so teams can coordinate quickly across sites.
- Text messaging for fast mass notifications, like evacuations or extreme weather events, and for workers to send custom or pre-set messages to monitoring personnel when help is needed.
Data and Analytics
Stay one step ahead of hazards, simplify compliance, and keep work moving safely with:
- Automated reporting that saves you time, shows if safety devices are being worn, turned on, and calibrated for easier compliance management.
- Historical trend data on gas leaks and exposures supports incident investigation, root cause analysis, and continuous improvement of gas safety practices.
- ZoneAware to draw site-specific areas and understand who is in each zone, spot bottlenecks, and monitor movement to muster points.
