Quad-Gas Bump Test Cylinder

This four-gas cylinder combines combustible gas at the lower explosive limit, oxygen, carbon monoxide and hydrogen sulphide in a single certified mixture. It enables rapid one-step bump testing of standard multi-gas detectors, verifying every sensor simultaneously to confirm alarm response and instrument readiness before each shift or confined space entry.

Product Description

The Quad-Gas Bump Test Cylinder is purpose-built for the most common configuration of portable multi-gas detectors, delivering combustible gas at the lower explosive limit, oxygen, carbon monoxide and hydrogen sulphide from a single vessel. By presenting all four target gases at once, it allows technicians to bump test every sensor in a detector simultaneously, confirming that each channel responds and alarms correctly within seconds rather than cycling through separate reference gases. This dramatically speeds up pre-shift checks and confined space entry preparation across busy industrial sites in the GCC and India.

Because the mixture includes reactive hydrogen sulphide, the cylinder incorporates an appropriately treated interior to keep the toxic component stable at its certified concentration. Every unit is supplied with traceable certification documenting all four gas values at fill, supporting audit and compliance requirements. Compatible with fixed-flow and demand-flow regulators, the cylinder integrates easily with manual bump stations and automated docking systems. Its blend of speed, convenience and certified accuracy makes it an essential consumable for any programme that relies on standard four-gas detectors to protect workers from combustible, oxygen and toxic hazards.
