The GX4 Gas Monitor helps warn your team when monitored gases reach unsafe levels near a supplied breathing-air source. This collection makes it easier to keep the unit configured, powered, calibrated and ready for work.

Shop replacement gas-sensor cartridges for carbon monoxide, oxygen and hydrogen sulfide, along with calibration gas, flow regulators, calibration adapters, sensor manifold tubes, air-supply hoses and inlet filters. You’ll also find power components, mounting hardware, field cases, auxiliary connections, strobe lights and remote alarm accessories.

Sensor cartridges, calibration gas and regulators must be selected for the gas being monitored. Follow the current GX4 instructions for installation, bump checks, calibration and sensor replacement. Operating conditions or contamination in the breathing-air line can affect sensor performance and service life.

Need the complete unit rather than a replacement component? Shop the GVS-RPB GX4 Gas Monitor. If you’re unsure which sensor, regulator or fitting is required, tell us about your current GX4 configuration and we’ll help you identify the correct part.
