The SIGI EX is a multi range measurement device for flammable gases with an internal pump. Like many other Esders instruments the well known operating concept with a menu technology driven by two function keys is also used for the SIGI EX. Furthermore it is possible to make pressure measurements (optional) and leak detection together with the SIGI EX P. One problem on an installation is a low gas pressure or a failure of the gas regulator. That is why the SIGI EX is together with the functions of monitoring the explosion limits and leak detection a powerful testing device for pressure tests of in-house gas installations.
