## Description

Klein Tools ET120 Gas Leak Detector, Combustible Gas Leak Tester with 18-Inch Gooseneck Has Range 50 - 10,000 ppm, Includes Pouch, Batteries : desertcart.in: Home Improvement

Review: A little disappointed to find that the batteries that came with the unit were flat and wouldn’t power the unit. Once batteries were changed everything was fine.
Review: I had to weigh up getting in a gas professional to diagnose severity and location of a possible leak and buying this product.. I did the latter, because I was not prepared to wait. I'm glad I did - old gas oven was leaking past 10mill PPM. Turned off at the mains. No other leaks. Really glad I bought into the tool and took care of it myself. I also appeciate having low or high sensitivity. Only criticism would be I'd like a high PPM for the big leak, but really trivial when it's designed for finding small leaks, more than anything.

## Features

- WIDE DETECTION RANGE: Detect gas concentrations from approximately 50 to 10,000 ppm* (*based on Methane) for versatile gas monitoring
- ADJUSTABLE SENSITIVITY: Choose between High (50 to 1000 ppm) and Low (1000 to 10,000 ppm) sensitivity levels for accurate gas detection
- ENHANCED VISUAL AND AUDIBLE ALERTS: Stay alerted with five red LED's (visual) and 85dB audible alerts that intensify as gas concentration increases
- EASY CALIBRATION: Automatic zero-point calibration at power-up ensures accuracy; flashing lights during self-calibration, no gas presence indicated
- FLEXIBLE GOOSENECK DESIGN: Expand the sensor's reach with the 18-inch flexible gooseneck that conveniently clips onto the meter for storage
- COMFORTABLE AND DURABLE: Over-molded body provides a comfortable grip for prolonged use and is designed to withstand demanding environments
- BATTERY SAVING FEATURE: Auto power-off after 10 minutes of non-usage conserves battery life, ensuring long-lasting operation
