OXY4400 - Oxygen Analyzer

SpectraSensors OXY4400 Oxygen Analyzer is a compact stand-alone one-channel meter with LCD display and data logger. The electronics are certified for hazardous area use. The sensor probe is inserted into the process stream and is connected to the controller by an optical fiber.

Full sample conditioning systems are available with the OXY4400 as well as software for PC interface.

Product Code: 11810

Application Note

Low Maintenance
The analyzer uses an optical method that detects oxygen using a probe that is inserted into the gas stream. The probe can be easily cleaned and has a lifetime measured in years.

Calibration of the analyzer is a simple procedure that can be performed in minutes using a binary standard with oxygen in nitrogen.

Accurate and Reliable
The OXY4400 technology is ideally suited for measuring in Natural Gas.

The sensor is not affected by even high levels of H2S or other sulfur species. There is no cross sensitivity to contaminants or other gases in natural gas.

The accuracy and reliability of the measurements are superior to electrochemical analyzers because the measurement does not drift.
