PLEASE NOTE: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator (like the 400-100 Calibration Test Gas Regulator) may be required.
Due to government regulations, shipping of compressed gases requires special handling and extra costs depending on the ship-to address. Please contact the Nuvair sales team for assistance with ordering test gases.
$65 additional charge for air delivery or shipments outside of the United States. No shipments to APO addresses allowed.
