Total Indoor Air Quality Total Indoor Air Quality With the worldwide need for accurate monitoring of indoor air quality, Greystone’s new IAQ is a Total Indoor Air Quality Monitor. The IAQ will monitor up to 6 parameters that include Particulate Matter (PM1.0, PM2.5, PM4.0 & PM10), Volatile Organic Compounds, Carbon Dioxide, Formaldehyde, Humidity &…
Heating, ventilation and air conditioning (HVAC) technology is becoming more and more important for residential and commercial buildings. Temperature sensors are used to measure temperature in many different applications and industries. Monitoring temperature is crucial for some following reasons: Health and safety of individuals High temperatures can lead to dehydration, heat exhaustion, and even heat…
Next to an electrical failure, water leaks are the second most common reason for computer room data loss. Commercial water leak detectors are very inexpensive when compared to the expense of data loss. Water leak detection is commonly installed in data centers, communications rooms, and other information technology dependent structures. In data centers, many water…
What do football/soccer, basketball, ice hockey, boxing and concerts all have in common? HVAC. HVAC equipment and technicians have a much bigger hand in making major sporting events possible than you might realize. And we are proud to say that Greystone played a part in making FIFA World Cup 2022 possible as our sensors and…
CO2 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…
Carbon 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…
Condensation is what happens when water vapour changes from a gaseous to a liquid state. Condensation occurs when warmer moist air comes in contact with cold surfaces such as framing members, windows and other accessories, or the colder region within the insulation envelope (if moisture has penetrated the vapour retarder). Warm air, having the ability…
A 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…
Humidity 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…
Greenhouses are indoor horticulture facilities that are optimized for growing certain crops. During flowering stage, high-wattage lights are needed which produce a significant amount of waste heat. Plants are watered frequently, and the soil medium is moist, so the heat from lights causes water to evaporate. Plants also naturally transpire. Consequently, the amount of…
