System Description
The Series 3500 Trace Oxygen Transmitter features an advanced electrochemical oxygen sensor that provides exceptional performance, accuracy, and stability. In addition, the enhanced mechanical design of the sensor ensures longer life, and virtually eliminates leakage of caustic electrolyte, a nagging problem associated with sensors that require periodic electrolyte maintenance. And, because the sensor is sealed, it is not position sensitive. In addition, Alpha Omega Instruments oxygen sensors are temperature compensated to provide optimum performance over a wide range of operating conditions.
