TeledyneModel DG7 Series -Intelligent Toxic and Flammable Gas Detectors

SHARE

The DG7 Series is a group of intelligent gas detectors employs a wide choice of sensor types. The DGI -TT7-E is used for Toxic gases or Oxygen monitoring. The DG-TT7-S is a solid-state metal oxide semiconductor. The DG-TX7 employs a pair of OXYCOL catalytic sensors. All DGi-TT7 are constructed from a common housing and electronics with the detection properties being determined by the type of sensor (cartridge) used. A wide range of cells are available, these cells are intrisically safe protected, and may be replaced with the detector powered which minimises the system down time.
