iGA Sample Specifications
Fathom Systems intelligent Gas Analysers are modular in format with a number of configurations available to meet with the specific dive system requirements.
The overall system make-up is dependent on the certifying and compliance standards with which it must meet and this ultimately dictates the configuration of the Gas Analysis system and the individual system chassis’ which form the overall networked system. In all instances, or indeed most, there is a requirement for the O2 Master Unit and CO2 Slave, which are then accompanied by a specific Sample Gas Processor, the type of which is dictated by the service being provided. Fathom Systems now offer sample gas pressure gauge panels as part of the system chassis in conjunction with the gas processor. These are supplied with the front panel indicating the service provided in clear anodic print. In lieu of the sample gas pressure gauge panel, a 4th analyser module may be installed. The product type is again dictated by where it is to be used and may range from either an O2 Injection Unit (for main living chamber and transfer), 6-Input Sample Manifold (for cross-check scanning) to a ppO2 Fuel Cell (for Bell sampling).
All Fathom Systems intelligent Gas Analyser products are supplied in 19” x 3U rackmount chassis format, either for conventional front install in a standard 19” rack or rear install as a flush fit to a SAT or Dive Control panel.
Below are just a few samples of typical configurations and their area of use.
