Klein Tools ET190 Gas Leak Detector – Wide Range, Audible & LED Alerts, Slim & Lightweight

Introducing the Klein Tools ET190 Gas Leak Detector

Meet a compact, pocket-friendly tool designed for fast, reliable screening of combustible gases. The ET190 covers a wide range from 100 to 2,000 ppm, enabling users to detect both small signs of a leak and more noticeable releases with confidence. Its slim profile and lightweight construction make it a natural companion for everyday inspections, service calls, and routine diagnostics.

Wide range for versatile screening

The 100–2,000 ppm detection span is crafted to adapt to different environments—from residential kitchens and mechanical rooms to industrial workspaces. This broad sensitivity helps your team quickly triage situations and decide when to escalate checks or shut down equipment for safety.

• Broad coverage supports quick triage across settings
• Helps differentiate minor signs from more significant releases

Clear feedback you can rely on

Visual and audible cues are designed to grab attention where it matters. Bright LED indicators pair with escalating tones to keep you informed in bright rooms or noisy job sites, ensuring you won’t miss a potential gas release.

Designed for field use

The ET190’s pocket-sized form is paired with a sturdy clip, making it easy to carry in a pocket or tool pouch between checks. Its compact design does not sacrifice durability, so you can rely on it during daily use on the job.

• Pocket-sized convenience for quick, on-the-spot screening
• Durable enough for daily professional use

Fast, trustworthy startup

Automatic zeroing occurs within about 30 seconds at startup, establishing a stable baseline and helping you move from idle to action quickly without manual calibration.

Dual sensitivity modes

Switch between High and Low sensitivity to tailor tests to the task at hand. High sensitivity helps reveal subtle changes, while Low sensitivity reduces background noise when screening larger areas.

Heritage and reliability

Backed by Klein Tools’ six generations of engineering and a long-standing American heritage, the ET190 reflects a commitment to quality, precision, and tools designed to stand up to professional demands. It’s a practical choice for tradespeople who value consistency and real-world performance.
