The zero air supply is an accessory device for a variety of gas calibrators. It can produce a non-contaminant air with sufficient pressure and flow rate to supply a variety of gas calibrators to dilute the standard gas for calibration and verification of zero and full amplitude. The feeder itself needs to have a pressure regulator, a temperature control device, and a filter for removing pollutants. In addition, an air compressor and an air temporary storage tank are required.
