Inventor(s)Rogero; Lawrence R. (Santa Barbara, CA); Trobridge; Rex G. (Costa Mesa, CA); Castleman; Luis J. (Goleta, CA); Schneider; Tracy L. (Santa Barbara, CA)
AbstractAn Automated data collection system for fugitive emission sources includes a handheld data terminal formed as a single portable package or integral unit. The data terminal is connected to an organic vapor analyzer (OVA) and an emissions receiving probe. The data terminal includes a display, a keypad, a microprocessor, a memory, a barcode reader and an analog to digital (A/D) converter for converting the emissions signal received from the OVA to a digital representation. The data terminal facilitates immediate on-site repair by providing repair guidance or repair options to the inspector during the inspections process. Front and rear magnets detachably mount the probe to the data terminal. The probe's rear magnet is recessed to matingly receive the unit's projecting rear magnet.

What is claimed is:

1. Apparatus for taking a gas sample at a release point tagged with an identification tag having a scannable identification code thereon, comprising:

a gas probe having a front mounting portion and a rear mounting portion spaced from said front mounting portion;

a gas analyzer coupled to said probe, said gas analyzer analyzing the gas sample received from said probe and generating a concentration signal representative of the concentration of a component of the gas sample;

means for scanning the identification tag and providing an identification code signal representative of the identification code;

means for storing said identification code signal and said concentration signal;

a display on which said concentration signal can be continuously displayed; and

a data terminal housing said scanning means, said display and said storing means, said data terminal having a front mounting pad selectively engageable with said front mounting portion and a rear mounting pad selectively engageable with said rear mounting portion, said probe being disposed in an operative orientation when s
