DM-TT6-K
The DM-TT6-K is a MultiTox detector, based on catharometric transducer. Its measurement
range is usually expressed in terms of %vol. relative to a particular gas (for example 5 %vol.
H
2
, 5 %vol. He...).
The DM-TT6-K measurement principle is based on the heat exchange between a heated
filament and a "cold" separation. The effectiveness of the exchange between those two
elements depends, in particular, of the thermal conductivity value of the mixture which
separate them.
This measurement principle is very stable, and able to operate with high gas concentrations.
In this configuration, the presence of oxygen is not essential, and catalytic poisoning is not an
issue.

Technical specifications
Each detector is constructed as follows:
•
A wall-mounted support secured by two screws, allows assembly of a cable gland
(M20) (optional) and up to three plugs.
•
An explosion-proof housing (epoxy coated aluminium or 316 SS) containing:
•
A set of tropicalized electronic cards
•
An infrared communication head, located on the detector’s housing. It
allows communication with the remote control (TLU600).
•
A colour coded cartridge. Yellow for Combustible Gas Detector with thermo-catalytic
cells (DM-TX6-X) and brown for catharometers (DM-TT6-K). The cartridge is located
in the lower part of the detector, and it is connected to the detector body by an open
ring leaving the label visible.
