G7 Multi-gas
Detector with Pump

Confident, connected confined space gas monitoring.

Our multi-gas pump cartridge gives you unprecedented control over each confined space entry and leak check your team performs. Quickly adapt to the environment or evolving circumstances by flipping between diffusion and pump configuration modes at any time – and all with the standard features of G7 single-gas and multi-gas devices, including inherent connectivity to cloud-hosted data, allowing you to proactively discover potential hazards, find opportunities to increase productivity and drive efficiencies in events such as evacuations.

Reliable connectivity and ultimate control

Without complicated Wi-Fi or mesh networks to manage and maintain, G7 multi-gas pump monitors deliver unrivaled coverage and unlimited support to seamlessly address all your confined space entry workflow and safety program needs

You can streamline workflows by customizing how your G7 devices operate, turning the pump on and off as needs change.

Pre-entry mode

Select ‘pre-entry’ mode to turn on the internal pump. Pre-entry mode automates and simplifies confined space sampling processes. Never again rely on assumptions, instead, trust the safety of a space knowing that it was properly sampled. Combined with a user-entered length of tubing, G7 provides a sample timer that instructs users how long to wait before proceeding.

About G7

All of our devices integrate seamlessly within the rest of our connected ecosystem, delivering an array of industry-leading tools and services to help keep your teams safe and amplify your productivity.


Cellular Connectivity

With integrated 4G/3G connectivity, G7c automatically watches over employees and lone workers, instantly linking them to the Blackline Cloud via available cellular networks. Workers can take comfort knowing they can communicate with monitoring personnel or control room staff in real-time using the exclusive two-way speakerphone. And since it's intrinsically safe, there's no need to purchase or carry an additional, expensive cell phone. G7c delivers simple, robust connectivity to account for the wellbeing of workers across all industries — without ever having to manually configure a network.


Satellite Connectivity

Our G7x system leverages satellite connectivity to wirelessly link your workers to the Blackline Cloud via the robust Iridium satellite network, wherever they may be working. Users can communicate with monitoring or control room personnel via two-way text messaging to account for their safety or communicate critical situational insights during an incident. Consisting of our G7x wearable monitor and G7 Bridge portable Iridium satellite uplink unit, the G7x system ensures the wellbeing of your teams is always accounted for — even in the most remote or offshore locations.
