Process Analyzer for Oxygen by Paramagnetic Sensor, Model : 412 Series, Brand : Nova

The Nova 412 Series O2 analyzers utilize a magneto-dynamic paramagnetic measuring cell and powerful selenium cobalt magnet assembly with on-board pre-amplification to provide the highest standard of O2 analysis. Accuracy is further augmented by built-in barometric pressure compensation and detector temperature control. For high purity applications ( Model 412HP) , a high resolution digital readout is added. Specifications Method of Detection Magneto-dynamic paramagnetic O2 cell Ranges Available 412 - any range from 0-2.0% to 0-100.0% O2; 412HP - 98.0 to 100.0 or 0 to 100.00 O2 Resolution 412 - 0.1% O2; 412HP - 0.01% O2 Accuracy & Repeatability ± 0.5% of full scale or 0.05% , whichever is greater Drift ± 0.2% of full scale per month Response Time ( T-90) 4-5 seconds Ambient Temperature Range 32 to 122° F ( 0 to 50° C) @ 5-95% RH non-condensing. Lower temperatures ( -5° F, -20° C) with Cold Weather Package. Sample dew point should be at least 9° F ( 5° C) below lowest sample temperature. Linearity ± 0.5% of full scale or 0.05% , whichever is greater Size & Weight Dimensions will vary depending on enclosure style and options required Power 115 VAC, 60 Hz - 220 VAC, 50 Hz Output Options 4-20 mA into 500 ohms non-isolated standard Isolated 4-20 mA, RS232, RS485, MODBUS, Ethernet outputs Alarms High and/ or low alarm contacts available, relay contacts SPDT 5A @ 220 VAC rating Analyzer Type O2 Analyzer Hazardous Area Rating Options General Purpose, Non-Hazardous Applications For continuous analysis of oxygen ( O2) in process gas streams that contain gases that interfere with other methods of O2 measurement. For high accuracy or high purity applications.
