Klein Tools Combustible Gas Leak Detector combines visual and audible alerts to provide clear indication when combustible gases are detected. Five red LEDs and an 85 dB audible alarm increase in response as gas concentration rises, helping users identify leak locations more effectively. The over-molded body provides a comfortable grip during inspections, while automatic power-off helps conserve battery life between uses. Supplied with batteries, a storage pouch, and an instruction manual, this gas leak detector is a practical tool for maintenance checks, troubleshooting, and safety inspections.
