Spectro Analyser

Product Description

Spectro Analyser The instrument has ranges of both 0-10 & 0-100 vpm with a sensitivity of less than 1 vpm. The analyser is based on a specially designed Pyrex quartz ionisation cell in which the sample gas flow is ionised in a high voltage alternating electrical field with consequential emission of light. A narrow spectral band corresponding to one of the specific light emission wavelengths of nitrogen is filtered by a narrow band-pass composite interference filter and then detected by a photomultiplier tube.. Specification Ranges: 0-10 vpm and 0-100 vpm Nitrogen in ArgonDisplay: Analogue meterLimit of detection: Less than 1 vpmSensitivity: Less than 1 vpmZero drift: Less than 0.1 vpm per CCycle/response time: Continuous/90% within 60 secsAccuracy: Depending on calibration gas available as it is a comparative method that is employedSample flow rate: 2 litres per minuteSample inlet temperature: 10C minimum, 30C max.Sample inlet pressure: Optimum 0.35 to 1.05 bar g; maximum 3.5 bar gSample outlet pressure: Maximum 0.15 bar gSample pipework: 6mm or 1/4 OD stainless steel and PTFEAnalogue output: 4-20 mA and 0-100 mVAlarm contacts: Adjustable high and low alarms with both normally open and closed voltage free contacts rated at 250V, 5A, AC non inductiveElectrical supply: 110/220V, 60 Hz or 220/240V, 50 Hz single phase
