G7c Series


G7c is the world’s first 3G-connected gas detector with integrated lone worker monitoring and evacuation management tools, connecting workers to live monitoring personnel in real-time. Work-anywhere 3G connectivity is complemented by an industrial two-way speakerphone, text messaging and location tracking.

Devices automatically watch over workers and call for help, even when the employee can’t. G7c delivers comprehensive gas coverage with an exclusive modular design, tailoring gas detection to every industry, application and scenario. Should a gas leak, fall or a no-motion incident be detected, assisted-GPS capability guides responders directly to the effected worker’s location.

G7c provides critical insights and situational awareness for optimized emergency responses, enabling teams to react with all the information necessary for rescues in complex, hazardous environments. Devices communicate all gas detection and safety incidents to live monitoring teams who can mobilize responders to an employee’s exact location or trigger evacuations in real-time when required.

With its high flow rate, real-time ppm concentrations or TWA values are displayed instantly with corresponding audible tick-rate indicator to precisely pinpoint leaks. Rapid clearing time enables accurate ambient-air leak detection using the probe along a chiller or display case. A re-zeroing algorithm and filter/bladder system allows the unit to be used in contaminated areas without affecting target gas readings. The rechargeable Li-ion battery provides a minimum of 8 hours of runtime for all-day usage.
