Picarro Develops Sensitive Atmospheric Monitor

Rob Spiegel, Contributing Editor -- Design News, October 22, 2007

Picarro, a manufacturer of trace gas analyzers, has produced the EnviroSense 3000i, a field-deployable, real time, ambient gas monitor. The monitor measures atmospheric levels of methane and carbon dioxide at parts-per-billion sensitivity, while monitoring water vapor at parts-per-million sensitivity. The EnviroSense 3000i was created to maintain high linearity, precision and accuracy over changing environmental conditions with minimal calibration.

The analyzer includes a high-precision wavelength monitor, designed to provide immunity to interfering gases, while also providing meticulous temperature and pressure control. The monitor offers robust digital signal processing that translates raw data into directly usable information. “Researchers investigating global climate change need measurements of greenhouse gases with extreme precision and accuracy to enable better models of the carbon cycle,” says Eric Crosson, CTO at Picarro. “The high accuracy, precision and low maintenance of EnviroSense 3000i make it ideally suited to address the demanding requirements of atmospheric air-monitoring applications.”

Light Matters: A High-Performance, "No-Compromise" Solid State Lamp?
First, let's define "no-compromise". In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package, and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
