Page 7: Product Description
MULTIXPLO AND MULTITOX DETECTORS OPERATING MANUAL Product description The DG-TX7-X is designed to monitor explosions risks induced by the presence of flammable gases or vapours (hydrogen, hydrocarbons, alcohol, etc.). The DG-TT7-K is designed to monitor the gas concentration in %vol. induced by the presence of some special gases or vapours (hydrogen, helium, carbon dioxide, etc.). -
Page 8: Dg-Tx7-X
MULTIXPLO AND MULTITOX DETECTORS OPERATING MANUAL DG-TX7-X Detectors are calibrated on 100% LEL (Lower Explosive Limit) of a particular-gas or vapour. The DG-TX7-X is a MultiXplo detector based on a thermo-catalytic oxidation transducer, which requires oxygen to function properly. In the event of a long period without oxygen, the measurement will no longer be representative of the concentration of gases or vapours. - Page 9 MULTIXPLO AND MULTITOX DETECTORS OPERATING MANUAL This cartridge is connected to the detector’s body by an open ring leaving the label visible. A coloured ring enables the identification of the device type at a larger distance. • A metallic support cable (optional) connects the wall mounting support and the housing, making the maintenance easier.
