G7c Wireless 1 to 5 Gas Detector

The Blackline Safety G7C is the world’s first direct-to-cloud connected gas detector. Integrated cellular communications allows the G7c to stream bump test, calibration and usage data to the Blackline Cloud, automating your regulatory compliance reporting. Spend less time retrieving data logs from the field and more time taking care of what's important.

The G7c can be configured for up to five different gases. The G7c uses a replaceable sensor cartidge that is available as either pumped or diffusion. Sensor cartridges can easily be replaced in the field, with each cartridge holding its own bump and calibration data.


G7 devices constantly stream situational data to the Blackline Live safety platform. The safety status of every team member is visible at a glance, and should something happen, this data can help identify precisely where to send help and how to prepare first responders for the scene.

With a fully-customized emergency response protocol, all your bases are covered. Choose to be notified by call, text or email in the event of an incident, or allow the Blackline Safety Operations Center to professionally manage every alert. Always be in control, even when you can’t physically be there.

Everything from alert management to bump and calibration status to real-time gas readings is updated to your web portal, directly from employee-worn G7 devices. With online device configuration and automatic over-the-air updates, your equipment is always current with zero downtime.
