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...

Volatile Organic Compound (VOC):
What is VOC:
Volatile Organic Compounds, more commonly known as VOC's consist of a wide variety of organic compounds that are vapor at room temperature. Many different gasses may make up VOC's, and some of those gasses may also be associated with other families of gasses. A complete list of VOC's can be found at the bottom of this page.
Health Risks of VOC's:
VOC's can cause respiratory, allergic, or immune effects...
EcoSensors devices have a variety of different sensors and calibration options and prodedures. These will vary by product and sensor used in that product. See the list below for your specific sensor and relevant calibration information. First, follow our short list of FAQ's to familirize yourself with general calibration inforamtion.

Non-Methane Hydrocarbons:
What are NMHCs:
Non-Methane Volatile Organic Compounds (NMVOCs) are a large variety of chemically different compounds such as benzene, ethanol, formaldehyde, cyclohexane, and acetone. NMVOCs are essentially identical to VOCs , with the exlusion of methane. An important subset of NMVOCs are NMHCs. NMHCs are trace atmospheric components that provide a sink for hydroxyl radicals and control ozone concentration. Exmples of NMHCs are ethane, ethene, propane, pro...
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...
