A built-in sample pump can be switched on to draw in the sample gas when it is at or slightly below atmospheric pressure. An external gas scrubber is available if required to remove any corrosive gases prior to entering the analyzer. In operation, a built in sample pump draws in the sample gas through sample conditioning filters and flow meter and then into the O2 sensor. The zirconia sensor is mounted in a flow-through block through which the sample gas flows. The sensor produces a non-linear µ A output proportional to the oxygen concentration. This non linear signal is then linearized and amplified by an O2 processor board. The output is then directed to a main amplifier board which then connects to the digital readout meter and optional recorder output terminals. SPECIFICATIONS Method of Detection: Temperature controlled zirconium oxide sensor in amperometric mode Ranges Available: Any range from 0-10 PPM to 96% O2 Resolution: 1 PPM Accuracy and Repeatability: ± 0.5% of full scale Drift: Zero: 1% of reading Span: 1% of reading per week ( non accumulating) Ambient Temperature Range: 32° to 105° F ( 0° -40° C) Linearity: ± 1% of full scale Size and Weight: BT style - approx. 8" W x 9" H x 10" D @ 12 lbs ( 20 x 23 x 25 cm @ 5.5 kg) K style - approx. 14" W x 6" H x 6½ " D @ 12 lbs ( 35½ x 15.2 x 26½ cm @ 5.5 kg) Power: AC/ DC operation, 115VAC 60Hz for recharging ( Other voltages available) Output Options: 4-20 mA or 0-1 VDC The 314 series analyzers should not be used on sample gases containing flammable gases. These gases will be burned by the zirconia sensor along with any available O2 and cause the analyzer to display readings that are lower than the actual values.
