Met One Instruments, Inc. Air Quality Tools for HVAC Operations

Ensure Efficiency & Optimal Air Quality in HVAC

Met One Instruments, Inc. offers selected weather sensors and handheld airborne particle and dust monitors to ensure HVAC systems work smoothly and efficiently. Our meteorological instruments measuring wind, temperature, relative humidity, and barometric pressure can help a smart system know when and how to operate.

Met One Instruments, Inc.’s handheld devices, which utilize light scatter technology, are an affordable way to monitor suspended particulate in the system to help ensure it is running cleanly and efficiently. In addition, data obtained from our particle counters and monitors can help determine when maintenance is needed—whether that be duct cleaning, a filter change, or other intervention.

Heating, air conditioning, and ventilation units and their ducts can be sources of mold, fungi, and other microbial pollutants, dust particles, secondary smoke, and other organic material. Testing and cleaning HVAC systems and ductwork is achieved through various methods. Typically, the “loosened” particulate matter is drawn throughout the HVAC systems before and after cleaning. Indoor air quality in an HVAC application can be quickly determined before and after the cleaning process with a particle counter. A particle counter can also assess equipment performance and aid in equipment inspection. Our handheld models 804 or GT-324 are instrumental in HVAC applications.
