Klein Tools et190 Combustible Gas Leak Detector

Product Description

The KLEIN TOOLS et190 is a compact, pocket-sized combustible gas leak detector designed for fast and accurate identification of gas leaks in residential and commercial environments. It detects combustible gases across a wide range from 50 to 2,000 parts per million (PPM), allowing it to catch both minor seeps and significant leaks. Multi-level LED visual alerts combined with audible alarms deliver immediate feedback, keeping technicians aware even in low-light or high-noise job site conditions. A 30-second automatic zeroing sequence on startup calibrates the sensor baseline before every use, reducing false positives and ensuring trusted readings from the first sweep.

The et190 is suited for gas leak surveys on natural gas and LP gas supply lines, fittings, valves, appliance connections, and meter sets. Its compact form factor allows technicians to reach tight spaces around water heaters, furnaces, boilers, and gas appliances where larger instruments are impractical. Plumbers, HVAC technicians, and gas fitters use this tool during commissioning, preventive maintenance, and service calls.

Key Features

• Detection range of 50 to 2,000 PPM covers both trace leaks and major failures
• Multi-level LED visual indicators show leak severity at a glance
• Audible alarm provides alert in noisy environments without relying on visual cues alone
• 30-second automatic zeroing on startup establishes an accurate baseline before each use
• Pocket-sized, compact body fits in a tool bag or shirt pocket for easy field carry

Compatibility

Designed for general-purpose detection of combustible gases, suitable for use on natural gas and LP gas piping systems, appliance connections, and fittings in residential and light commercial applications.

Installation Notes

This instrument is operated by licensed plumbers, HVAC technicians, and qualified gas service professionals. Before conducting a leak survey, shut off any ignition sources in the work area and ensure adequate ventilation. Allow the 30-second startup zeroing cycle to complete fully before beginning the sweep to ensure baseline accuracy. This detector is a survey and diagnostic tool and does not replace pressure testing procedures required by IFGC or local gas codes.
