The TIF8900 is a broadband, solid-state combustible gas detector that pinpoints the location of combustible gas leaks as low as 5 ppm, the company says. It can be used in virtually any situation where a combustible gas, vapor, or residue needs to be located, states the manufacturer. In addition, the gas detector can be used to verify the safety of potentially hazardous locations. This battery-powered unit features a flexible 16-inch probe. A Geiger counter-style ticking signal increases in frequency as the source of the combustible gas or vapor detected. The gas detector comes with a carrying case, owner's manual, rechargeable batteries, and recharger.
