    MULTITOX DETECTOR 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.
