Partial pressure readings typically increase data by~30%. ISO speed measurements are typically 10% less than AVSmeasurements for the same pump.‡ These are given for guidance, please contact Edwards for arecommendation of pump combinations best suited to yourapplication.Shop online at www.edwardsvacuum.com
