This document refers to the C-21 and earlier EcoSensors VOC Instruments
Replacement sensors for the C-21 are available from Gas Sensing for $50. Please contact us for ordering information.
The Eco Sensors C-21 responds to most reducing VOCs, but not with the same degree of response for each VOC. The response is essentially logarithmic. For the first half of the scale (to about the 2nd yellow bar), the response is approximately linear. After that, it gets sharply logarithmic (much more c...
Particulate Matter:
What is Particulate Matter:
Particulate matter is a complex mix of organic and inorganic substances, found in the atmosphere in both liquid and gas phases. Coarse particulates and fine particulates are differentiated by their aerodynamic diameter (greater or less than 2.5 micrometers). Course particales usually contain materials from the earth's crust and fugitive dust from roads and industries. Fine particles contain the secondarily formed aerosols, combus...
