CAPS True NO2 NOx NO Analyser (The Model 500)

The Model 500 CAPS NOx analyser uses superior Cavity Attenuated Phase Shift (CAPS) Spectroscopy to measure True NO2, NOx, and NO gases.

The instrument combines direct NO2 measurements with highly efficient gas phase titration (GPT) to convert and measure the NO gas component. An automatic baseline reference cycle accounts and compensates for any potential baseline drift due to varying environmental conditions.

CAPS technology is inherently accurate and sensitive, uses very little power, and requires far less maintenance than Chemiluminescence. The Model 500 raises the bar for NO2, NOx, and NO measurement accuracy, while simultaneously reducing instrument operation and maintenance costs.


Portable Aerosol Spectrometer Dust Decoder (model 11-D)

The model 11-D, in its compact and rugged design, combines all advantages of the previous portable GRIMM aerosol spectrometers with the improved optical detection, long-term battery operation, and facilitated handling.

Understanding the Effects of Biomass Burning on the Climate

A great new case study from our supplier, MPL, outlines how a Micro Pulse LiDAR system helped researchers at the Atmospheric Radiation Measurement (ARM) user facility on Ascension island better understand how particles from biomass burning in Africa affect the Earth’s cloud properties.
