The G7x gas monitors with lone worker monitoring leverage the G7 Bridge portable uplink base station to connect to available cellular and satellite networks. Connectivity transitions effortlessly to satellite when 3G is unavailable to ensure constant safety monitoring. G7x communicates with G7 Bridge using an industrial-strength 900 MHz radio link up to 2 km away. The G7 Bridge connects G7x employee-worn devices to the Blackline Safety Network via satellite or cellular networks.

The G7x can be tailored to specific work environments with the ability to replace the sensor cartridge within the field. Choose and change from single or quad gas options. Cartridge options include:

  • Standard - lone worker safety
  • Single Gas - customisable single gas options
  • Quad Gas - monitor for up to four gases

With wireless connectivity each G7c gas detector can be remotely configured and firmware updates are automatic allowing consistent and up-to-date operation.

Every safety incident and gas alert is communicated instantly to Blackline Safety for storage and reporting.
