Wireless Gas Detectors

Battery-powered and line-powered wireless gas monitors that detect toxic, combustible, and VOC hazards and report readings back to a central controller over GDSCorp wireless networks.

Fixed Gas Detectors

Permanently installed point gas monitors using electrochemical, infrared, catalytic bead, and PID sensor technologies. Cover toxic, combustible, VOC, and oxygen depletion hazards with 4-20mA and MODBUS outputs for wired plant integration.

Open Path Gas Detectors

Line-of-sight open path gas detectors using UV and infrared spectroscopy to monitor hydrocarbon, hydrogen sulphide, and ammonia gas clouds over long distances, up to 200 metres between transmitter and receiver.

Wireless System Accessories

Explosion-proof wireless transmitters that bridge legacy analog sensors and switch inputs into a GDSCorp wireless network, extending coverage without new cabling.
