Daiken Southland - Case Study
Daiken Southland Limited is a wood processing company that uses pine trees to manufacture Medium Density Fibreboard (MDF). The logs are chipped, broken down into individual fibres. Then a urea-formaldehyde resin is used to glue the wood fibres back together to form the various types of MDF. During the manufacturing process, formaldehyde is released to the atmosphere, and, therefore the local ...

The role of gas sensors
Monitoring of toxic and harmful gases such as formaldehyde and carbon monoxide in the home environment After the renovation of many new houses, more than 90% of harmful gases seriously exceed the standard, and the indoor formaldehyde concentration may exceed 2.5ppm, and some may even exceed 10ppm. Therefore, formaldehyde sensors, air quality sensors, TVOC sensors, etc. are placed in the home ...

Air quality monitoring equipment can be used to identify indoor pollutants
Indoor Air Quality (IAQ) IAQ (Indoor Air Quality) refers to Indoor air quality. It includes indoor air temperature, humidity, air cleanliness and fresh air volume. In the past, indoor air quality was mainly studied by temperature and humidity. This year, as a result of the introduction of air-conditioning system in modern buildings, office modernization, the popularity of household appliances and ...
