Honeywell BW Rig Rat Area Gas Monitoring

BW RigRat

Honeywell BW™ RigRat brings a new level of user-friendliness to transportable multi-gas area monitoring, so your people can work with confidence in hazardous areas. Simply place the monitor nearby, and it will alert workers to area gas threats so they can take action.

Complements your personal gas detectors, protecting workers wherever they’re at risk. Unlike some transportable area monitors, Honeywell BW RigRat is fully self-contained — with no need to repurpose your personal gas detectors for an area monitoring application. Instead, continue using your personal detectors to monitor workers’ breathing zone, while using Honeywell BW RigRat to monitor an area.

Up to six gas sensors — with the flexibility to switch them out as your needs change. Choose from more than 15 4R+ sensors for toxic gases, oxygen, and combustible gases at the lower explosive limit (LEL).
