Met One Instruments Industrial Hygiene Products

Tools to Monitor INDUSTRIAL air quality

Met One Instruments offers selected sensors and handheld devices useful in ensuring Industrial Hygiene systems operate smoothly and efficiently. Our meteorological instruments measure wind, temperature, barometric pressure, and relative humidity to help a system know when and how to operate. Other devices monitor particulates in the system to help ensure it is running cleanly and efficiently. Data from our monitors can help determine when maintenance is needed—whether that be duct cleaning, a filter change or other intervention. Met One Instruments sensors and monitors are affordable and reliable.

Heating, air conditioning and ventilation units as well as their ducts can be sources of mold, fungi, and other microbial pollutants, dust particles, secondary smoke and organic material. Testing and cleaning HVAC systems in general, and the ductwork in particular, are achieved through various methods. Typically, the “loosened” particulate matter is drawn throughout the HVAC systems, both prior to and after cleaning. Indoor air quality in an HVAC application can quickly be determined before and after the cleaning process with a particle counter. Additionally, a particle counter can be used to verify equipment performance in building management as well as inspect equipment and ducting. Met One’s handheld models the 804 or GT-324 are particularly ideal for HVAC applications.
