SIGI EX

Navigation

Description

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.
The following operating modes are used in the menu

  • Workplace monitoring
    (Measurement of LEL; 0-50 % LEL)
  • Tracing gas in pipeline networks
    (Measurement of gas concentration from ppm to 100 Vol.% with auto ranging)
  • Leak detection in houses
    (Measurement of gas concentration on gas installations and alarm on LEL; ppm to 50% LEL)
  • Pipe filling / Gas purity
    (Measurement range from 0 to 100 Vol.%)

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, together with the functions of monitoring the explosion limits and leak detection, is a powerful testing device for pressure tests of in-house gas installations.
The construction of the device head with a built in pump guarantees an extremely short indication time of flammable gas concentrations. The hydrophobic filter is easy to exchange and provides a protection of the device from water and dust. As an extra option a flexible probe with quick connector, a test adapter and chargers for 12 volt and 230 volt are available.
