This will allow the Gas-Pro to be zeroed using clean air as the base point. If the Gas-Pro is zeroed in contaminated air a false gas reading can result, or the zero could fail.

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.
