Overview
The ENVEA PAS Sense 1314i is a photoacoustic infrared gas analyzer that measures up to five gases plus water vapor with ppb-level sensitivity. It compensates for temperature, pressure, humidity and known gas interferences to deliver stable results with minimal maintenance and no consumables. The instrument provides a linear response across a wide dynamic range and typically requires a maximum of two calibrations per year.

Features and benefits

• Measures up to five gases plus water vapor
• Selective measurement of a broad range of gases and vapors
• Linear response across a wide dynamic range
• Stable operation: typically only two calibrations per year
• User-friendly: calibration, configuration and data viewing/analysis via PC
• Accurate: compensates temperature and pressure fluctuations, water vapor and known gas interferences
• Extremely low-volume purge capability
• Immediate operation: virtually no warm-up required
• Remote control via TCP/IP network interface
• Expandable to up to 16 locations with the 700MPS multipoint sampler and datalogger software
• Rack-mountable

• Detection of airborne pollutants absorbing in the mid-IR with ppb detection capability

Technical information
Measured gases: EtO, SF6, CO2, NH3, Ethanol, N2O, CO, H2O
Detection limit: gas dependent, typically in the ppb region; detection limit can be calculated for a chosen sample integration time (S.I.T.). Detection limit referenced at 5 s S.I.T.
Dynamic range: typically 4 orders of magnitude (expandable to 5 orders using two span concentrations)
Zero drift: typically ± detection limit per 3 months
Repeatability: 1% of measured value
Range drift: ±2.5% of measured value per 3 months
Influence of temperature (detection limit): ±10% of detection limit/°C
Influence of temperature (range drift): ±0.3% of measured value/°C
Influence of pressure (detection limit): ±0.5% of detection limit/mbar
Influence of pressure (range drift): -0.01% of measured value/mbar
Interference handling: automatic compensation for temperature and pressure fluctuations in the analysis cell; can compensate for water vapor and cross-compensate for a known interferent with an optical filter installed
Acoustic sensitivity: not influenced by external sound
Vibration sensitivity: strong vibrations at 20 Hz can affect detection limit
Internal data storage: 131072 measurement cycles (~22 days at 15 s cycle time)
Dimensions (HxWxD) & weight: 175 x 483 x 375 mm / 14 kg
Communication: USB, Ethernet and RS232
