Picarro Announces General Availability of EnviroSense 3000i Multi-Species Atmospheric Monitor

Unrivaled accuracy, precision and stability help scientists observe and

understand the earth's carbon cycle

    SUNNYVALE, Calif., Aug. 30 /PRNewswire/ -- Picarro, leading
 manufacturer of high-performance trace gas analyzers based on patented
 Cavity Ring-Down Spectroscopy (CRDS) technology today announced the general
 availability of the EnviroSense 3000i atmospheric monitor.
     EnviroSense 3000i is a field-deployable, real-time, ambient gas monitor
 that measures atmospheric levels of methane and carbon dioxide with
 parts-per-billion (ppbv) sensitivity and water vapor with parts-per-million
 (ppmv) sensitivity.
     "Researchers investigating global climate change need measurements of
 greenhouse gases with extreme precision and accuracy to enable better
 models of the carbon cycle," stated Dr. Eric Crosson, Chief Technology
 Officer at Picarro. "The high accuracy, excellent precision and low
 maintenance of EnviroSense 3000i make it ideally suited to address the
 demanding requirements of atmospheric air-monitoring applications."
     Existing atmospheric monitors based on non-dispersive infrared (NDIR)
 sensors have known problems -- they are non-linear, sensitive to water
 vapor concentration, and susceptible to drift. Furthermore, these
 instruments require extensive modifications and sample conditioning,
 frequent calibration, and significant post processing of the data.
     In contrast, EnviroSense 3000i maintains high linearity, precision, and
 accuracy over changing environmental conditions, with minimal calibration.
 The unique capabilities of the underlying CRDS technology are complemented
 by a superior analyzer design, including a high-precision wavelength
 monitor providing immunity to interfering gases, meticulous temperature and
 pressure control, and robust digital signal processing that transforms raw
 data into directly useable information.
     Deployment in several atmospheric monitoring and meteorological
 facilities, including Penn State University, has shown that the analyzer
 requires minimal recalibration and no sample conditioning.
     "The EnviroSense 3000i analyzers are providing invaluable field
 measurements," said Ken Davis, Associate Professor of Meteorology at Penn
 State University. "High-precision and high-accuracy measurements of
 atmospheric composition, like those acquired by the Picarro EnviroSense
 analyzer, are essential to our ability to observe and understand the
 earth's carbon cycle. Picarro has been very responsive to our scientific
 needs." "We deployed 5 EnviroSense units in an experimental observational
 network in the spring of 2007," said Scott Richardson, Research Associate
 at Penn State, "and we have found the stability of the instruments to be
 truly remarkable. The instruments should significantly simplify the task of
 obtaining high-quality measurements of atmospheric composition."
     EnviroSense 3000i is the first of a suite of analyzers designed to
 support scientists who investigate global climate change. Two additional
 monitors will be introduced shortly: EnviroSense 2000f, a flux methane and
 carbon dioxide analyzer, and EnviroSense 2000i (isotopic CO2 and CH4).
