The principle of our SONIC LEAK DETECTOR™
) is to pick up any sound with a frequency higher than what we can hear, from 15 kHz up to 200 kHz. this wide range is made possible by using a sophisticated microphone. Most manufacturers only listen to frequencies around 40KHz.
Detection depends on the amount of leak, if it is a tiny slow leak, it might produce bubbles in water. This will be very hard to detect because the slow speed of escape of the gas will not produce vortices, so no noise will be generated.
If the escaping gas is more rapid, then it can be detected – and you can work out what equipment you need depending on the volume of the noise is.
If it is loud, then a pair of padded headphones are needed as opposed to the simple skeleton headphones provided with the set as standard.
Because our SONIC LEAK DETECTOR™ has such a wide frequency range, it makes it a very good bat detector, picking up any species of bat, as it doesn’t need to be tuned to any particular frequency.
