G7 Field replaceable Sensor Cartridges by Blackline Safety

Blackline Safety G7 gas sensor cartridge optionsMaximise your uptime with Field-replaceable cartridges

The G7 sensor cartridges can be easily and quickly changed out in the field with new, pre-calibrated replacements once sensors reach the end of their operating life. Maximising the G7c and G7x uptime minimising the maintenance time.

The flexibility of the modular interface allows the device to be converted on-site from a single to a quad-gas monitor in seconds. The G7 combines 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 is damaged, the cartridge can be easily switched out for a new one. No more costly repairs or extended product downtimes.

The Standard Cartridge features Blackline’s exclusive green SureSafe® light — when the light is on, workers can be confident that they’re connected to the Blackline Safety Network and that their safety is being monitored.
