G7c & G7x Gas Detector Sensor Cartridges


G7c & G7x Gas Detector Sensor Cartridges from Blackline SafetyField replaceable modular sensor cartridge for the G7 Lone Worker devices.

The ability to change your G7c or G7x Lone worker device into a lone worker with gas detector or gas detector alone is simple with Blackline Safety's field replaceable modular gas sensor cartridges. Available in single gas or multi gas options. The G7 provides three cartridge options to support gas detection, lone workers and evacuation management. The selection of gas sensors in each cartridge can be customized and configured for specific work environments.

Each cartridge features Blackline Safety’s exclusive green SureSafe® light — when the light is on, workers can be confident knowing that they are connected to the Blackline Safety Network and that their safety is being monitored.

Change out sensor cartridges in the field means more uptime

Blackline's Sensor Cartridges can be easily and quickly changed in the field with new, pre-calibrated replacements once sensors reach the end of their operating life. Device uptime is maximised and maintenance time is minimised, ultimately saving your businesses money.

The G7’s modular interface allows the device to be converted whilst on-site from a single to a quad-gas monitor in seconds. Combining the efficiency of a disposable gas detector with the innovation of a connected safety monitor — its modular design reduces the total number of devices needed, as one G7 can function as both a single and a quad-gas monitor, effectively reducing overall costs. When a sensor reaches the end of its serviceable life or gets damaged, the cartridge can be switched out int the field for a new one. 

Cartridge Options

Standard Cartridge

The standard cartridge is designed for lone worker safety monitoring. Suitable for applications where lone worker monitoring is the priority with no exposure to gas hazards. All sensor cartridges feature Blackline Safety's excluse green SureSafe® light, workers can be confident that when the light is on their safety is being monitored as they are connected to the Blackline Safety Network.


Single Gas Cartridge

The G7c or G7x with a single-gas cartridge operates as a gas detector and lone worker safety device, capable of monitoring your choice of one gas type. With a Single-gas cartridge, devices are customisable for specific working scenarios for when multi-gas coverage is not required.


Quad/Multi Gas Cartridge

Adding the Quad-gas cartridge the G7 device allows it to operate as a multi gas detector and lone worker safety device, delivering comprehensive gas detection coverage of up to four gases. Sensor combinations are customisable in order to tailor gas detection to complex, hazardous working environments.


Gases Detected

The G7 devices with Single-gas or Quad-gas cartridges are compatible with a variety of gas sensors. Blackline Safety currently offers gas sensors to detect hydrogen sulfide (H­2S), explosive gases (LEL), carbon monoxide (CO) and oxygen (O2).

Under development: Sulfur dioxide (SO2), hydrogen resistant carbon monoxide (CO-H) and ammonia (NH3)
