bw technologies portable gas detectors -LEAK DETECTOR EZ SENSE


The most economical solution to detect leaks of Methane, Propane, Butane, LPG and Natural Gas. Compact and very light, just approach it to the possible gas leak to intercept it. Acoustic alarm and yellow or red LED display for different levels of gas alarm. It does not need calibration.

Detecting natural gas, propane, butane, LPG and LNG has never been so ez

ez sense is the most convenient way to detect natural gas, propane, butane, LPG and LNG. It is compact and light on the pocket in more ways than one.

ez sense utilises a catalytic bead sensor which requires absolutely no calibration to individual gases or fuel types – simply point and click!
It is suitable for identifying the source of leaks in pipes, fittings, valves, gas storage tank/ cylinders and hot water heaters.
This product is also an opportunity to quickly inform your customers as to the source and size of a leak and undoubtedly provide some peace of mind at the same time.


Ez to use
Simply check the suspected area by pointing ez sense close to the source. If gas is present the alarm will sound and the yellow LED or the red LED will light up according to the concentration of gas. It couldn’t be simpler.

Ez to test
ez sense can be tested quickly and easily by releasing a small amount of gas (butane) in a well ventilated area. The alarm should sound and the yellow or red LED light will come on.

Ez to look after
ez sense doesn’t react well to water – it will damage the instrument. So please keep it in a dry environment.
Also avoid using it in areas of high humidity. If, for any reason, ez sense is redundant for several weeks, it is advisable to remove the batteries to prevent any corrosive damage.
