Solid State (MOS) Hydrogen Sulfide Detector - MultiTox DG-TT7-S

The MultiTox DG-TT7-S intelligent solid-state (MOS) hydrogen sulfide (H2S) gas detector has been designed for effortless operation and maintenance in dry and hot environments.

The DG-TT7-S is a solid-state metal oxide semiconductor (MOS) gas detector chiefly used for the detection of hydrogen sulfide in arid locations having air present. It is also possible to configure this gas detector for other gases, such as refrigerants (e.g. R22). The unit uses a robust sensing element that requires recalibration only once a year. A high gas concentration dose is also not needed by the device in order to reactivate the active sensing material.

The intelligent, microprocessor driven unit can be completely configured using the hard wired HART option providing true flexibility to the installer or by using a wireless hand-held terminal (TLU). Elements such as alarm levels and relay operation are all set via the TLU; a hazardous area approved hand-held unit. It is also possible to directly interface the unit with a variety of panels, PLCs and controllers etc. The device offers HART Protocol 7th edition output is offered as an option.
