Where Are VOC Gases Found?
Volatile organic compounds are found as a component in furniture items, such as varnishes, paints, glues and waxes, and many degreasers and cleaning products. Organic compounds, when used, emit VOC gases. These gases also remain in the air long after use. One example is formaldehyde, a VOC gas that evaporates from paint, having a boiling point of -19°C. Therefore, people use special VOC gas detector to monitor VOC gas. Users will choose a resized VOC gas detector to ensure worker safety.
What Are VOC Gases?
VOC gases are chemical compounds where one of the elements is carbon. Volatile organic compound gases are compound gases that have a high vapor pressure and low water solubility.Volatile organic compounds are a class of man-made chemicals.
VOC’s are usually components of petroleum fuels, paint thinners, by-products from industrial processes, and dry-cleaning agents. Some VOC gases have short or long-term health effects with high concentrations indoors around certain office equipment. The volatility of VOC is due to its extremely low boiling point, which causes a large number of molecules to evaporate from the liquid compound and then penetrate the nearby air.
Health Impacts of VOC Gases
Anthropogenic VOCs are man-made, especially when indoor concentrations are elevated. Harmful VOC gases are not inherently toxic; however, they have to compound long-term health effects as concentrations are low and thus symptoms develop slowly over time.
Often they are detectable by scent, however, some have no odour at all. The level of odour doesn’t give much indication of the amount of risk from inhalation and some highly dangerous VOC gases emit no scent at all.
Detecting VOC Gases with International Gas Detectors
VOC gases are an important element of a range of industrial processes and products. They can be detected using specialized gas detection sensors as well as PID technology.
Places, where VOC’s are often present, must closely monitor their environment and surroundings using a fixed VOC gas detector. These instruments are permanent installations that offer constant measurement of VOC gases in the air they sample.
We have many years of experience in VOC testing and fixed VOC gas testing solutions. We have released a new range of PID sensors that incorporate technology superior to current alternatives on the market. Some of the key factors include:
- 70% cost saving using our leading addressable technology；
- Not affected by humidity changes；
- Wide selection of ranges available depending on the VOC gas type；
- Unique electrode stack design enhancing low level accuracy and reducing long term drift；
- The detector has over limit acousto-optic alarm function；
- The device has a 7-inch waterproof liquid crystal touch screen, easy to observe the value;
- The detector has automatic calibration function, high measuring precision.
