The Agilent 571 Bayard-Alpert gauge offers high performance over a pressure range of 2 x 10^-10 to 1 x 10^-3 Torr (2.6 x 10^-10 to 1.33 x 10^-3 mbar). The 571 gauge withstands long periods of degassing or accidental exposure to atmospheric pressure while at operating temperature and will still recover its original characteristics. A reference gauge is also available, sealed off at ≤ 5 x 10^-6 Torr for use in testing a gauge controller.

High vacuum range from 2 x 10^-10 to 1 x 10^-3 Torr (5 x 10^-10 to 6.7 x 10^-2 mbar)
Rugged design can withstand long periods of degassing or accidental exposure to atmosphere at operating temperature and still recover its original characteristics
Yttria-coated iridium filament that resists oxidation for longer life
High X-ray limit allows the gauge to give more accurate readings at lower pressure
