Specifications:
Accuracy and Resolution: At constant temperature, accuracy better than 1% of calibrated span, Resolution to 1 ppm/0.0001%
Analog Outputs: 0 - 5 Volts for 0 - 100 ppm/10 Pa, to 0 - 20%/kPa carbon dioxide in eleven ranges, plus separate outputs for optical bench temperature and barometric pressure, 4 ranges each; short circuit protected; 16 bits (up to 1 in 65535) voltage resolution in each
Concentration Ranges:Optimized for 0-6% (long optical bench), 0-10% (long optical bench) or 0-15% (long optical bench) CO2
Flow Rates: 5 - 2000+ ml/min. Effect of flow rate on readings from 20 - 500 ml/minute is negligible; not damaged by non-condensing moisture; particulates are trapped by built-in filter
Noise and Drift: At constant temperature, flow rate and CO2 concentration- Noise < 3 ppm pk-pk (5 second digital filtration setting), 10 ppm pk-pk (no filtration) over 20 minutes near zero; Zero drift < 0.002% over 24 hours
Panel Display: Two line 16 character alphanumeric. Line 1- CO2 concentration to 0.1 or 1 ppm, 0.001% or 0.01%, depending on concentration; or partial pressure of CO2. Line 2- barometric pressure to 0.001 kPa. Display also used for user interface menu system
Response time:< 0.5 second for 10% to 90% of a step change (200 ml/minute, medium optical bench, no averaging)
Serial Output: Carbon dioxide concentration (to 0.1 ppm), barometric pressure (to 0.001 kPa), and optical bench temperature (to 0.001 deg C) with comma delimiters, updated at user selectable intervals from 0.1 second to 5 minutes
Size:12" x 10" x 4" (30 x 25 x 10 cm)
Technology: Dual wavelength infrared with gold-plated optical path
Weight:5 lb (3 kg)
