RAE Systems AutoRAE Calibration Station Differential Pressure Recorders which is designed to meetAutoRAE is an auto calibration, bump test and charging system for RAE Systems gas monitors. AutoRAE cradles are available for the QRAE, QRAE Plus, MultiRAE Plus and MiniRAE 2000. Press the button once for a bump test, twice for calibration, and walk away. A few minutes later, easy to read LEDs inform you of the status of the gas monitor's sensors. If the monitor fails the bump test, the system automatically performs a calibration. An optional external
