D12 Toxic & Combustible Gas Detector
Brand: Analytical Technology IncATI's D12 Toxic and Combustible Gas Transmitter will accept up to 46 different sensors, greatly reducing the need for multiple gas transmitter models.
The self-aligning sensor holder simply plugs in, with automatic gas sensor recognition and verification when contact is made.
For many toxic and combustible gases, ATI offers a unique sensor response testing system unmatched by any competitive transmitter.
Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to ensure system integrity.
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.
D12 gas transmitters provide useful features that simplify installation, operation, and maintenance.
From clear menu-driven setup pages to large numerical display of gas values, you simply can’t find a more versatile gas transmitter.
Gas concentrations are displayed in large, easy to read numbers.
The display also provides alarm indication and complete menus for setting up operating parameters.
Backlighting is available when operating in 3-wire mode.
Operating functions such as calibration, alarm setup, alarm reset, data view, and setup options are all available using a magnetic tool. It is not necessary to open the enclosure when making adjustments.
