Double O-rings minimize moisture ingress and water damage to the instrument's electronics
PetroFLAG does not distinguish between aromatic and aliphatic hydrocarbons but quantifies all fuels
the meter has a single measurement range so no range adjustment is required
you don't have to estimate the slope and roughness of the channel
Flow control is accomplished by occluding or restricting and thus accelerating the air flow through the venturi
RAE Systems AutoRAE Calibration Station Differential Pressure Recorders Double O-rings minimize moisture ingressAutoRAE 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
