A system for monitoring gases including sample, dilution, test, and control subsystems. The sample subsystem has a gas probe assembly defining a first end of a sample line and disposed in an area or adjacent to an object to be monitored. A sample pump in the sample line provides a positive motive force for drawing a sample and a sample pressure detector provides a sample pressure signal which is proportional to the sample flow rate. The dilution subsystem includes a dilution line having a first end vented to atmosphere. A dilution pump mounted in the dilution line provides a positive motive force for drawing the dilution air and a dilution pressure detector provides a dilution pressure signal which is proportional to the dilution flow rate. The test subsystem includes a test line having a first end in fluid communication with the second ends of the sample and dilution lines. At least one gas sensor senses the presence of a gas in the test line and provides a gas signal proportional to the level of sensed gas in the test line.

Monitoring system

The present invention is an instrument identification system and method for a confined space gas detector used to assure user safety conditions or to collect gas concentration and gas type data at a multitude of known predetermined locations. The system consists of information buttons with touch sensor contacts used for transferring ID type data comprising small stainless steel canisters containing computer memory programmed to store data pertaining to individuals and locations. The system further comprises a receptacle connector with electrical contacts coupled to a confined space gas detector for transferring information from the information buttons, where the gas detector, receptacle and receptacle contacts are contained within a portable integral housing.
