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...

Acid Gas: What is Acid Gas: Acid gas is a type of natural gas or any other gas mixture that contains significant quantities of hydrogen sulfide, carbon dioxide, sulfur oxides, nitrogen oxides, hydrogen halides, or similar acidic gases. Acid gases form acidic solutions when dissolved in water. Before a raw natural gas containing hydrogen sulfide or carbon dioxide can be used, the gas must be treated to reduce impurities to acceptable levels. This is commonly done with amine gas t...

Combustible Gas:   What is Combustble Gas: Combustible gas is a gas that can burn in the air or in Oxygen. Examples of combustible gases are Hydrogen, Methane, Propane, Iso-butane. Mixture of a certain amount of combustible gas and Oxygen will explode in the presence of an ignition source. Combustible gas is a typical cause of gas explosion accidents. Health Risks: Breathing in combustible gas vapor can cause headache, nausea, and dizziness. Extremely high level...
