LI-7000 CO2/H2O Analyzer Specifications
 Type: Differential, non-dispersive infrared gas analyzer. Detectors: Two solid state detectors; one each for CO2 and H2O, filtered at 4.255 and 2.595 microns, respectively. Chopping Frequency: 600 hertz. Source: Single source, lifetime > 20000 hours. Optical Bench: One optical bench. Sample cell size: 9.53 mm Dia. x 152.4 mm L (3/8" x 6"). Volume: 10.86 cm3. Warm-up Time: Approximately 2 minutes to operation; 2 hours to temperature equilibration. Gas Pressure: Maximum allowable pressure is 115 kPa (17 psi) with pressure sensor connected. 200 kPa (29 psi) max. w/o pressure sensor connected. Maximum Flow through Analyzer: >50 liters/min. Internal Pump: Yes Display: 40 character x 8 line backlit LCD. Back Panel Connections: Analog: 4 user-scalable 14 bit DACs, 300 Hz update frequency. RS-232: 9600 baud, 8, N, 1. Supports XON/XOFF. Auxiliary Input Channels: 2, -2.5 to +2.5V. Common mode input voltage range ±2.5V. Tubing Connections: Swagelok. Power Requirements: 100-240 VAC, 50-60 Hz, or 10.5-16 VDC, 4 amp max. Power Consumption: 15-40 Watts DC (dependent on temperature and pump usage). Temperature Range: 0-50 °C ambient, 0-55 °C bench. Size: 5" H x 9.875" D x 14.5" L (12.7 x 25 x 36.8 cm). Weight: 19.4 lbs. (8.8 kg). CO2 Analyzer SpecificationsRange: 0-3000 ppm. Accuracy: 1% nominal. Zero Drift (with temperature): ±0.3 ppm/°C. Span Drift: ±0.2% of reading/°C. Water Sensitivity: <0.1 ppm CO2/mmol/mol H2O (Software algorithm corrects for dilution effects). Calibration: Factory linearization over 0-3000 ppm range using NIST-traceable standard gases. Pressure Range: 0 to 115 kPa absolute. Display Resolution: 0.1 µmol/mol. Signal Noise: See table below. H2O Analyzer SpecificationsRange: 0-60 mmol/mol. Optical bench and interconnecting hoses must be maintained above the dewpoint temperature by the user. Accuracy: 1%. Zero Drift: ±0.2 mmol/mol/°C. Span Drift: ±0.4% of reading/°C. Signal Noise: See table below. Calibration: LI-610
