Photoacoustic Gas Monitor INNOVA 1412i

The LumaSense Photoacoustic Gas Monitor INNOVA 1412i is a highly accurate, reliable and stable quantitative field gas monitor. Its measurement principle is based on the photoacoustic infrared detection method . This means that the 1412i can measure a

Photoacoustic Gas Monitor INNOVA 1412i at a glance:

• Selectively measures a wide range of gases/vapors
• Linear response over a wide dynamic range
• Highest stability (low drift) makes calibration only necessary 1-2 times a year
• User-friendly: easy procedures for calibration, configuration and measurement data presentation and analysis on PC
• Accurate – compensates for temperature and pressure fluctuations, water-vapor interference and interference from other known gases
• Extremely low-volume flushing possible
• Operates immediately almost no warm-up time is necessary
• Remote control capability via TCP/IP (Ethernet) through the plant LAN using the LumaSoft Gas Single Point 7810 or Multi Point 7860 software (optional)
• Expandable up to 24 locations using 1309 Multipoint Sampler(optional)

Specification

• Measurement Technique: Photoacoustic infrared spectroscopy.
• Detection Limit: Gas-dependent, but typically in the ppb region. Using the Gas Detection Limits chart, the detection limit for a selected sample integration time (S.I.T.) can be calculated.
• Dynamic Range: Typically 4 orders of magnitude (i.e. 10,000 times the detection limit at 5 S.I.T.). Using two span concentra-tions it can be expanded to 5 orders of magnitude.
• Zero Drift: Typically ± Detection limit per 3 months
• Influence of temperature: +/- 10 % of detection limit/°C.
• Influence of Pressure: +/-0,5 % of detection limit/mbar.
• Repeatability: 1 % of measured value
• Range Drift: +/- 2,5 % of measured value per 3 months.
• Influence of temperature: 0,3 % of measured value/°C.
• Influence of pressure: -0,01 % of measured value/mbar.
• Interference: The 1412i automatically compensates for temperature and pressure fluctuations in its analysis cell and can compensate for water vapor in the air sample. If an optical filter is installed to measure a known interferent, the 1412i can cross compen¬sate for the interferent.
• Acoustic Sensitivity: not influenced by external sound.
• Vibration Sensitivity: strong vibrations at 20Hz can affect the detection limit.
• Internal Data Storage Capacity: Dependent on the number of gases being measured. Sufficient for a 12-day monitor¬ing task, monitoring 5 gases and water vapor every 10 min.
• Pumping Rate: 30 cm3/s (flushing sampling tube) and 5 cm3/s (flushing measurement chamber).
• Power Requirement: 100-240 VAC +/- 10%, 50-60 Hz.
• Power Consumption: 120 VA.
• Total Internal Volume: The total Internal Volume of the measurement system: 60cm3
• Alarm Relay Socket: for connection to one or two alarm relays (visual/audio). Alarm levels for each gas are user-defined. Max. 25 VDC, max.100 mA.

• Ventilation and air exchange measurements using tracer-gas
