  • Page 7: Product Description

    OPERATING MANUAL Product description The DGi-TT7-E is designed to monitor poisoning risk induced by the presence of toxic gases or vapours (hydrogen sulphide, carbon monoxide, ammonia...). The DGi-TT7-O is designed to monitor the oxygen concentration in %vol either for inerting (scales 1 or 5%vol.) or in breathable atmosphere control (Scale 0-25%vol).

  • Page 8: Dgi-Tt7-E

    MultiTox Detector OPERATING MANUAL DGi-TT7-E The DGi-TT7-E is a MultiTox detector based on a transducer with electrochemical cell, which requires oxygen to function properly. The measuring principle is based on a redox reaction. In the event of a long period without oxygen, the measurement will not be representative of gases or vapours concentration.

  • Page 9: Technical Specifications

    • A colour coded cartridge with a label located in the lower part of the detector, a green one for the toxic gas detectors with electrochemical cell (DGi-TT7-E), a blue one for the oxygen deficiency gas detectors with electrochemical cell (DGi-TT7-O) and an orange one for semi-conductor toxic gas detectors (DG-TT7-S) The cartridge is connected to the detector’s body by an open ring leaving the label visible.

  • Page 10: Detection Cartridge

    OPERATING MANUAL Detection cartridge Detection cartridges are: • Intrinsic safety “ia” for the DGi-TT7-E- and DGi-TT7-O versions. They can be removed when the detector is powered. • Explosion proof “d” for the DG-TT7-S versions. They cannot be removed when the detector is powered.
