Detail Nova 322 Series Paramagnetic Oxygen Analyzer
The Nova 322 Portable Paramagnetic Analyzer is designed to measure the oxygen concetration of clean, dry sample gas. A built-in pressure regulator reduces any positive sample pressure. A built-in sample pump may 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. Specifications Method of Detection Magneto-dynamic paramagnetic O2 cell Ranges Available Any range from 0-2.0% to 0-100.0% O2 Resolution 0.1% O2 Accuracy & Repeatability Model 322BT: ± 1% of full scale; Model 322HABT: ± 0.5% of full scale Drift ± 0.5% of full scale per month Response Time ( T-90) 4-6 seconds Ambient Temperature Range 0-50 º C, 32-122 º F Linearity Model 322BT: ± 1% of full scale; Model 322HABT: ± 0.5% of full scale Size & Weight 8 " W x 9 " H x 10 " D @ 12 lbs ( 20 x 23 x 25 cm @ 5.5kg) Power AC/ DC Operation, 115 VAC 60 Hz for recharging ( Other voltages available) Output Options 4-20mA or 0-1V ( optional) Alarms One high or one low O2 alarm ( optional) Hazardous Area Rating Options General Purpose, Non-Hazardous Applications For continuous high accuracy analysis of oxygen O2 in process gas streams or other applications such as combustion air O2 enrichment, O2 defficiency analysis and many more. Features High accuracy paramagnetic O2 cell, very stable Fast response ( T90-4 to 5 seconds) Bright digital readout Linear over entire 0-100% range Non-consumable O2 cell, no periodic replacement required Built-in sample pump or pressure regulator To improve accuracy, cell is compensated for changes in barometric pressure Bench Top ( BT) enclosure is standard Options Isolated or non-isolated recorder outputs of 4-20mA Sample pre-cooler for hot samples Condensate removal for wet applications High or low O2 alarms Detachable/ portable datalogger Sensors temperature-controlled for maximum stability Calibration Analyzed calibratin gas of O2 free nitrogen ( N2) for zero Air at 20.9% O2 or analyzed calibration gas of O2 in N2 for span
