About This Product

In a school or training laboratory the detector is used to check gas taps, pipe joints and Bunsen burner connections for leaks, moving the probe along each fitting and listening for the alarm to change. It also lets students see how the reading rises as they approach a source of gas, which ties in with lessons on combustion and gas behaviour.
