This highly reliable Gas Leak Detector is ideal for Industrial uses such as in gas furnaces and plant maintenance. This affordable, reliable and simple to use portable unit is quick in locating gas leaks. Capable of detecting both propane and methane to high accuracy. 

A 5-level LED leak alarm and audible beep mean you are constantly updated on the level of gas detected. As a combustible gas or vapor source is approached, an audible signal (ticking sound) increases in frequency and the red lights illuminate in sequence, to show the intensity of the leak. 

The advantage of having this instrument is that it comes with a headphone jack so you never miss a beep in a busy or noisy environment and a mute function when u want to use just the LED leak alarm.
