Environmental Chemical Monitoring System
GD624
GD624 is an environmental chemical monitoring system that detects up to 24 gases at once using multi-sensor, multi-channel direct detection, integrating optical ionization, electrochemical and infrared sensors. It is built for real-time monitoring of toxic, hazardous and flammable gases in emergency response, firefighting and industrial environments.
Overview
Product information at a glance
An incident scene rarely involves one gas, and the picture changes as it develops. GD624 monitors up to twenty-four gases and vapours simultaneously and keeps monitoring, so responders work from a live picture of the atmosphere rather than a series of spot readings.
The system can be deployed fixed or mobile and starts with one click, which matters when it is being set up at a cordon under time pressure. Alongside gas concentrations it records environmental parameters including temperature, humidity, pressure, wind speed and wind direction, giving the context needed to interpret where a release is going.
GD624 works as a standalone unit or as a networked system: collection and control terminals can each operate independently, one control terminal supports multiple collection terminals, and built-in 4G links the system to a remote cloud for management, control and analysis. Collection terminals also support external video and thermal imaging, and data can be stored, replayed, exported and analysed after the event.
