Detail Nova 235 Series Oxygen Analyzer
The Nova 325 Portable Trace Oxygen Analyzer is designed for accurately measuring trace PPM oxygen in clean, dry sample gas. The customer replaceable electrochemical sensor produces a small output current directly proportional to the amount of O2 in the sample and is capable of measuring trace PPM levels of O2 in any range from 0-100 to 0-9999 PPM. The lowest readable level is 1 PPM. Specifications Method of Detection Low range electrochemical O2 sensor Ranges Available 0-100 PPM to 0-9999 PPM O2 Resolution 1 PPM Accuracy & Repeatability ± 2% of reading Drift ± 1% of full scale per week Response Time ( T-90) O2 sensor may require an initial purge down from air to low PPM O2, which may last up to 6 hours. After purge down, T-90 response from 1000 to 100 PPM is 30 seconds. Ambient Temperature Range 0-50 º C, 32-122 º F Linearity ± 2% of full scale Size & Weight 8 " W x 9 1/ 2 " H x 10 " D @ 12 lbs. ( 20 x 23 x 25 cm @ 5.5 kg) Power AC/ DC operation. 115 VAC 60 Hz for recharging ( Other voltages available) Output Options 0-1V or 4-20mA ( optional) Alarms One high or low O2 alarm ( optional) Hazardous Area Rating Options General Purpose, Non-Hazardous Applications For high accuracy analysis of trace PPM oxygen ( O2) in non-corrosive process gas. Features Rugged design that is light weight, compact and easy to operate. Fast warm-up and response. Accurately measures PPM O2 in gases including those containing hydrocarbons. any range between 0-100 to 0-9999 PPM available. Customer replaceable electrochemical ' fuel cell' O2 sensor. Blocking solenoid valves used to trap PPM O2 in cell for quick purge down and also protects cell during initial sample line purge. Comes complete with flow control valve, filters and flow meter. Digital meter readout with backlight. Rechargeable battery operation. Options Recorder outputs of 0-1V or 4-20 mA Sampel pre-cooler for hot samples Condensate removal for wet applications Built-in sample pump or pressure regulator AC only power operation O2 alarm with LED Detachable data logger Type ' K' suitcase style cabinet Calibration Analyzed calibration gas of O2 free nitrogen N2 for zero Analyzed calibrationg gas of PPM O2 in N2 for span Unique Applications The PPM O2 sensor in Model 325 can be affected by the presence of other gases such as H2S.
