Abstract
PURPOSE: To achieve the improvement in the accuracy of span calibration by providing a changeover range of 21 to 0% to a magnetic type oxygen analyzer of air standard type, changing the range to 21 to 0% at the span calibrating and supplying N2 pure gas as span gas.
CONSTITUTION: At the zero calibrating of the oxygen analyzer of 21 to 20% range, auxiliary gas dry air of the arrow B is used and valves 11 thru 13 are so operated that the air in the dotted line A as zero gas also flows through inlet port 2 into the measuring chamber 1. If the analyzer is operated, the swing of the meter pointer becomes zero and calibration may be accomplished. Next, to make span calibration, the analyzer of the 21 to 20% range is changed over to 21 to 0% range through range changing over and the valves 11 thru 13 are so operated that N2 pure gas as span gas flows into the chamber 1. If the swing of the meter pointer is adjusted, the span calibration may be accomplished. The analysis of high accuracy may be perrange through range changing over and performing span calibration by using the N2 pure gas of small absolute errors of density.
