Simtronics MultiTox DGI-TT7 Solid-State (MOS) Gas Detector

Designed For The Detection Of Hydrogen Sulfide In Dry Locations.

SKU
GDGITT7MOS

The MultiTox DG-TT7 Solid State Gas Detector is a reliable gas detector mainly used for the detection of hydrogen sulphide (H2S) in hot and dry environments. The device can also be configured to detect other gases, such as refrigerants (e.g. R22).

The sensing element in this robust unit only needs to be replaced once a year making this gas detector low maintenance. Additionally, the device does not need a high gas concentration to reactive the active sensing material.

The microprocessor driven unit is fully configurable using a wireless hand-held terminal (TLU) or through the use of a hard wired HART option. Elements such as relay operation and alarm levels are all

set via the TLU.

The device may also be interfaced directly with a wide range of panels, controllers and PLC’s.
