325BT便携式PPM的氧分析仪 The Nova 325 Portable Trace Oxygen Analyzer is designed for accurately measuring trace PPM oxygen in clean, dry sample gas. The customer replaceable electrochemical sensor produces a small output current directly proportional to the amount of O2 in the sample and is capable of measuring trace PPM levels of O2 in any range from 0-100 to 0-9999 PPM. The lowest readable level is 1 PPM. Bypass solenoid valves are used to trap low PPM oxygen in the O2 cell to avoid exposure to ambient air. This allows for a rapid purge down and also protects the cell from momentary over exposure to high O2 levels. A flow control valve and flow meter are provided for regulating the flow of samples under positive pressure. A built-in sample pump is provided for use on samples under atmospheric or slight negative pressure. A rechargeable battery provides enough power for the pump and electronics for about 20 hours of continuous opertion. The analyzer may still be operated while it is being charged. A red LED indicates when to recharge the analyzer and a green LED indicates that it is receiving recharging power. The battery recharger is included with the analyzer.
