G7c Series

The G7 Sensor Series detects O2, H2S, CO, and LELs, among other gasses, and provides real-time updates to a data center. The G7x Sensors does this through satellite connectivity while the G7c uses 3G communications — the only 3G gas detector available. The sensors can be equipped with single-gas, quad-gas, or standard cartridges, as well as a pump cartridge ideal for leach-check surveys.

Along with detecting gasses, the G7 Series provides real-time information (including location services) to protect lone workers.
The range of the G7 series varies, although distances of up to a mile are generally safe and supported.
