S147 Rapid Response O2/CO2

The S147 Rapid Response O2/CO2 Analyzer has a built in pump which is set at 300 mL/min to draw samples in through the “Gas In” port located on the front of the analyzer. Gases exit the analyzer through the “Sample Vent” on the back panel.  Sampling and exhaust gas should be at or near atmospheric pressure to avoid pressurizing  the gas sensors.  On the front panel there is a “Ptach” input to a differential pressure sensor (pneumotachometer) which can be used for measurements such as breath flow.  This differential pressure sensor is open to atmosphere through the “Ptach Vent” on the back panel.  There are “Zero” and “Span” controls on the front  for calibrating the O2, CO2 and differential pressure sensors .   “Span” for CO2 and O2 should only be adjusted if calibration gases are available.   The pump speed control is located on the front panel and allows +/- 30ml/min adjustments from the factory setting of  300ml/min.

The back panel of the S147 Rapid Response Analyzer contains the power “on/off” switch, 12VDC, 5.4A  jack  and three analog outputs 0-5V for CO2, O2 and pressure signals. data collection cables are provided for connection to a data acquisition system. We recommend the C901 LoggerPro data acquisition software for data collection.
