Infrared equipped mobile unit provides efficient, low cost means of supplementing other survey methods; in Southern California Gas Co's case, surveys are obtained at one-tenth normal cost; principles and operation of infrared gas detection; instrument is sensitive to 5 ppm of methane in air; application of unit to vehicle transportation; limitations are adverse wind conditions, soil compaction, moisture content of soil; tight pavement over pipe line, dust conditions and speed of travel over pipe line; cost comparison of survey methods.
