The SGM595 LPG Gas Sensor is the gas sensor used with the complete range of Duomo conventional detector panels. This is the LPG version of the SGM595. For the Methane CH4 (Natural Gas) see SGM595 Methane Gas Sensor

We have installed and commissioned natural gas and carbon monoxide sensors for applications such as:

  • Boiler rooms
  • Kitchens
  • Car parks
  • Aircraft hangers
  • Factories
  • Shopping centres

The SGM595 is an easy to install product. It sends signals back to the Duomo gas detector panel (please see below) that powers it. Then, the Gas Sensor interprets the signal and can sound alarms whilst turning off gas supplies to the protected area. As a result, a gas cannot escape into the atmosphere.

Because of its automatic drift compensation feature, the SGM595 is now one of our most popular gas sensors. To ensure efficacy and extend sensor life, Duomo recommend servicing at a minimum of every 12 months.

We manufacture all Duomo products to meet relevant European standards and proposals for explosive and toxic gases. The gas industry recognise Duomo for providing a comprehensive range of low cost, high reliability gas detection for many applications.

This LPG Gas Sensor is compatible with complete Duomo conventional Gas detection range GS100MGS300MGS300McBX444McBX150 & BX316.
