311XL SERIES TRACE OXYGEN ANALYZER 1. INTRODUCTION 1.1 Description: The Teledyne Analytical Instruments (TAI) Model 311XL and 311TCXL are portable, intrinsically safe trace oxygen analyzer which can be operated without an external power source. These analyzers will be referred to as Model 311XL or 3...

1.3.2 Reliable Calibration. Although this instrument can be calibrated with air, the use of a calibration gas gives better results on the lower PPM ranges. If the instrument is exposed to high concentrations of oxygen (percent levels), it will take a significant amount of time to purge the oxygen fr...

A current limiting resistor (R1 and R2) is potted into the end of each battery. This assures that under no circumstances can more than 25 milliamperes (100 milliwatts) be switched or drawn from either battery supply. This means that the Model 311XL may be used in explosive atmospheres where arcs of ...

For positive pressure applications, TAI suggests a simple throttle valve installed in the sample line between the sample point and the analyzer. ...

3.1 Introduction. The Model 311XL is supplied completely assembled and ready for instant use. The Micro-Fuel Cell must be installed prior use. When a sensor is first installed, the instrument should be purged for 12-16 hours with zero gas (an inert gas such as nitrogen or argon with less than 0.1 pp...

Span gas: An inert gas (nitrogen or argon) with a known trace amount of oxygen. The oxygen content should be 70 – 90% of the full scale on the range of interest (working or primary range). Note, if this instrument is exposed to high concentrations of oxygen (percent levels), it will take a significa...
