ATi’s D12 digital gas detector is a flexible, toxic and combustible gas detector that is compatible with up to 46 different sensors.

Fixed, toxic gas detector

The D12 digital gas detector is a flexible, toxic and combustible gas detector that accepts up to 46 different sensors, reducing the requirement of multiple transmitter models.

The self-aligning sensor holder simply plugs in, with automatic sensor recognition and verification when contact is made.

The unique sensor response testing system provides reliable response checks to insure system integrity, which includes outdoor weather conditions. The sensor response is verified with an actual gas sample, generated on demand. Generators store run time information accessible to operators, and are automatically tested for compatibility with the installed sensor.

Features & specification

  • Backlit LCD Display
  • Non-Intrusive operating functions such as calibration, alarm setup, alarm reset, data view, and setup
  • Options are all available using a magnetic tool.
  • No need to open the enclosure when making adjustments.
  • Password Protection
  • Modular Electronics
  • Scalable 4-20 mA: The output range for a particular sensor is programmable within the range boundaries set in that sensor.
  • Three Internal Alarm Relays
  • Analog Output Simulation
  • Relay Output Simulation
  • Serial Communication Interface
