GasCheck G4 advanced gas leak detector

At the heart of the instrument is a sensor which can detect any gas with a different thermal conductivity to that of air. Leaks can be located, and the gas leak rate shown on the large LCD colour display in a choice of convenient units. The handheld leak detector holds an easily selected internal library of gases specific to your application. Datalogging with the GasCheck G4 is now possible over a long period of time (up to 10 days continuous) meaning less back and forth to download data.

As part of the GasCheck G4 kit you receive a lightweight portable carry case, which is a good source of protection when the device is in transit. The carry case holds the handheld gas leak detector, key accessories, and cables, more of which are available separately.
