Oxygen Analyzer for fast response and research applications.

The Model O2 is a versatile research grade oxygen analyzer for measuring 5-100% oxygen concentrations. The unit includes an integrated gas sampling pump, flow controller, bright LED display for oxygen concentration and status indication, touch panel controls for ease of operation, 0-1Volt DC analog and a terminal strip with relay outputs and a 4-20ma analog output, a separate digital RS-232 output, and LEUR type front panel connection for response times. The front panel allows control of flow, alarm set-points, calibration, and other user features. The Model O2 has a CE clearance and can be used in research and other applications, but not approved for human medical use or diagnostics. Oxigraf OxiSoft software is also included with the unit for computer display and data logging under Windows.
