Ambetronics Oxygen Analyzer, Ambetronics' Percent Oxygen Analyzer - OGA-3500-VOL is a microcontroller based equipment designed for measuring the concentration of oxygen (%V/V) content in a tube through which inert gas (nitrogen or argon) is flowing. It is capable of measuring the low concentration of Oxygen in the range of 0 to 29.99 %V/V or 0 to 9.999 %V/V.It is based on Electrochemical (Galvanic cell) type measurement method. The flow meter can be used with pressurized sources like gas cylinder or pipeline.The unit provides suction pump to create sufficient negative pressure. Isolation of Trace sensor can also be achieved. Range selection, Alarms set & Span set facility is provided on front panel. Alarm Output with 0 to 1 VDC & 4 to 20 mA DC proportional to oxygen concentration is provided at back of Panel.Unit can be wall mounted using brackets or Panel mounted.Salient features:-Dual Display of Gas Concentration & Set Point of Alarm / Unit of GasMicro-controller Based Latest, Accurate, Reliable & High Performance Technology that Eliminates False alarmAdvance Warning and Alarm Output.Two Independent Alarm Relay OutputProgrammable Linear 4-20mA and 0-10V / 0-1V with Respect to Gas Concentration.Easy one man calibration at siteUser Friendly OperationAudio Visual Alarm Indication.Applications:-Light Bulb ManufacturingBio TechnologyAir / Inert / Noble GasesPlastic ManufacturerCryogenicsControlled gas Environment.Glove BoxesChemical ManufacturingFood and beverageRubber PolymerizationGlan ManufacturerHigh purity gas manufacturer.
