The GAS CHECK 3000 series of gas leak detectors identifies the source of gas leaks quickly and easily, and enables you to quantitatively measure any leakage found. Hand held and cordless, the GAS CHECK is simply traced around suspect flanges, valves, and joints - leaks are pin-pointed with an audible alarm and a direct leak rate reading in a choice of units. This is particularly useful when working to quality or emission standards that should be below a certain level. The instrument can be used with one hand and the special flexible long probe provided allows easy access to difficult to reach areas. There are various models to choose from, including a BASEEFA approved intrinsically safe version.
