Natural Gas Detector : Sigi EX - SImple Gas Indicator

Find your Best Natural Gas detector among all Natural Gas Detector and Natural Gas Leak Detectors for Natural Gas Leak Detection & Measurement. Gas measurement instrument for flammable gases...

Why you need Natural Gas Detector & Natural Gas Leak Detectors?

Few fires are more dangerous and destructive as gas fires. Few homes are designed with any sensory detection for gas leaks despite the dependency our home appliances have on natural gas. A natural gas detector can provide you with additional protection for your home by alerting you to potential danger so you remain safe. Natural gas is commonplace due to modern utilities and is frequently used as fuel for home appliances. As its use becomes more prevalent, being cautious and aware will help to prevent dangers to you and your family. There are many things to consider when it comes to natural gas, including: how it is being used in your home, what can cause a natural gas leak, and what type of natural gas leak detector would be best for protecting you. By learning about natural gas, you will be better prepared to handle any difficult gas-related situation that may arise and create an overall safer home.

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.


  • Improved sensor technology and adjustment options
  • Increased operating temperature range of -20 to +50 ° C
  • By up to 44% larger display area for better readability
  • Red backlight for improved perception of alarm messages
  • Simpler handling of the battery and battery connection mechanism
  • Extension of the operating time by about 30%
  • Representation of the individual menu items (fields of application) in plain text

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, gaspurity (measurement range from 0 to 100 Vol.%) 

The display shows useful informations like the peak value or leak rate. 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.

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 options a flexible probe with quick connector, a test adapter and chargers for 12 volt and 230 volt are available.

  • Extremely rugged and light weight hand-held measurement device
  • Internal pump and filter technology
  • Menu technology and function keys for easy operating
  • Automatic start in last used operating mode
  • Display of useful extra information, peak value and leak rate
