GfG MSHA G450 4 Gas Detector (Alkaline) G450M-11410
Description
Protect your team in confined spaces with the GfG G450—the gas detector that keeps workers safe without breaking the budget.
When lives depend on early detection, you need a detector you can trust. The G450 is MSHA-approved and monitors four critical gases: LEL, O2, CO, and H2S. Its 0.1 ppm H2S resolution meets the latest TLV standards, giving you the precision that matters when seconds count.
Built for the job. One-button operation means no confusion in an emergency. The compact, rugged design fits easily into a toolkit, while the bright 360° LED alarm and three-color backlight ensure every team member sees the alert—even in poor visibility. Completely automatic calibration takes the guesswork out of maintenance.
Real durability, real savings. Three-year warranties on all sensors—including replacements—mean the G450 delivers the lowest cost-of-ownership in its class. Interchangeable alkaline battery packs run up to 24 hours continuously, and the IP67 water resistance handles jobsite conditions. Standard event and datalogging keep you compliant and informed.
What's included: detector, sensors, calibration adapter, manual, and CD. Everything you need to start protecting workers today.
