    2.4.1 Diffusion monitoring If you wish to monitor gases in ambient air for dangerous levels, the Gas-Pro can be worn by either clipping the strong alligator clip to clothing/overalls in the breathing zone or through the use of a chest harness.

  • Page 22: Pumped Mode

    33). Gas-Pro can either be worn or used with hoses and probes to sample from spaces prior to entry. The pump capacity in the Gas-Pro is 0.5l/m and will draw a sample of gas from 30m within 80 seconds. Please note the expected losses for some gases below. Please allow at least 3 seconds per meter of hose used.

  • Page 23: Manual Sampling

    1 minute is recommended to ensure a stable sample is read. If the Gas-Pro being used is fitted with a carbon monoxide sensor (CO) a 5% increase in reading is expected during this process due to the extra pressure placed on the sensor (ie if the sample being tested is 30ppm –...
