The MultiXplo DM-TX6 intelligent catalytic sensor based flammable gas detector used to detect a wide range of gases, including hydrogen (H2). The device has been designed for ease of installation, operation and maintenance in testing environments.

The DM-TX6 uses a computer matched pair of poison resistant pellistor beads to provide reliable flammable gas detection performance in harsh environments, provided oxygen is present. 

The intelligent, microprocessor driven unit is fully configurable using a wireless handheld terminal (TLU] giving true flexibility to the installer. Parameters such as relay operation and alarm levels are all set via the TLU, hazardous area approved handheld unit.  In addition, the sensor element is protected by the onboard electronics to prevent exposure to over-range LEL gas concentrations. This helps reduce ongoing maintenance and service costs.

The device offers a wide range of output options as standard and is suitable for use in SIL 2 appLications. The unit may be interfaced directly with a wide range of panels, controllers and PLC·s etc.
