What is ppm gas detection?
When it comes to personal protective equipment (PPE) for hazardous and toxic gases, the National Institute for Occupational Safety and Health (NIOSH) recommends different levels of protection based on the amount of exposure in parts per million. While ppm is a common unit of measure, Gas detection Australia can also be confusing for people who are unfamiliar with it.
To make things easier, ChemDAQ offers a simple video that provides an overview of PPM gas measurement in easy to understand terms. This will help you better understand how your ppm gas detector can protect your workers.
Parts Per Million Explained
In a world where many harmful, combustible and explosive gases are being used, it is important to know what PPM gas measurement means for your workers. Using PPM gas detection to keep your employees safe will save them both time and money.
Measuring NH3 and Acetone in Air
Ammonia, acetone and ethylene oxide are all very toxic and often cause respiratory or skin damage when inhaled. They can also cause serious health problems, such as kidney and liver disease if inhaled for long periods of time.
Detecting these gases requires the use of a gas sensor that can respond quickly to changes in concentration. Several solid state gas sensors are available, including those based on metal oxides and polymeric materials. These sensors rely on redox reaction1 to detect the presence of gas. The sensitivity of these sensors can vary greatly depending on the metal oxide used as the sensing material and their working temperature, so they must be carefully selected.
