Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel.

DetailsCO2 as it is used in building ventilation control is not a contaminant with a specific danger threshold not to be exceeded. Rather, it is an indicator of the outside air dilution rate of a space where the outside CO2 levels provide a baseline reference for outside air. Indoors CO2 levels will increase beyond this…
DetailsCarbon dioxide, also called CO2, is a colorless, odorless gas. You may have also seen carbon dioxide in its solid form through dry ice. As CO2 heats up, it goes right from solid to gas, so you can’t see liquid carbon dioxide. Carbon dioxide (CO2) is a greenhouse gas. This means that it causes an…
DetailsCondensation is what happens when water vapour changes from a gaseous to a liquid state.

Warm air, having the ability…
DetailsA cleanroom is an engineered space, which maintains a very low concentration of airborne particulates. It is well isolated, well-controlled from contamination, and actively cleansed. Cleanrooms are an important part of any laboratory — compared to the ambient outdoor air in urban areas, which contain 35 million particles per cubic meter, cleanroom environments offer just…
DetailsHumidity is the amount of water vapour in the atmosphere. Water vapour enters the atmosphere by evaporating from large bodies of water on the Earth’s surface such as lakes, oceans and seas. There are several ways to measure Humidity, but it is most often measured in terms of Absolute Humidity (AH), Relative Humidity (RH) and…
