Zero Air gas is clean, dry air that is used for calibrating gas detection equipment. It is commonly used to set what we call the Zero Point on a gas detector. This is the equivalent of telling your gas sensor "this is what it looks like if the hazard is not present." Most calibrations will have you set a zero first. If you are in an environment with background gases such as CO, Butane, etc and you attempt to Zero the detector it will throw off your sensor. Use zeroing gas on the sensor before you zero and you'll ensure that the gas detector gets a clean zero point.
